Echocardiography was used to evaluate left ventricular mass (LVM), end-systolic volume (ESV), end-diastolic volume (EDV), interventricular septal wall thickness (IVSWT), stroke volume, and ejection fraction (EF). Also, the Bruce treadmill test was employed to estimate VO2max.,Background: High-intensity interval training (HIIT) is a time-efficient alternative to traditional prolonged training. In contrast to ample evidence describing the effects of prolonged training, there are few data describing cardiovascular adaptations arising from HIIT interventions.,Results: The HIIT subjects showed a significant increase in EDV (P = 0.001), LVM (P = 0.002), stroke volume (P = 0.003), and EF (P = 0.001). However, there was no change in ESV due to HIIT (P = 0.916). Additionally, following HIIT, IVSat, 27 Feb 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=38067Conclusions: This rare observation supports the role of immunosuppressive therapy in preventing the recurrence of life-threatening vascular lesions in the management of Behcet’s disease.,Case Presentation: A 23-year-old man was diagnosed with Behcet’s disease, as revealed by a carotid aneurysm, and was treated with a prosthetic graft reconstruction as well as immunosuppressive therapy. The patient was lost to follow-up. He stopped the medications of his own will 1 month after his discharge from the hospital. Two years later, he presented with chest pain of 1 week’s duration. A large aneurysm involving a long aorta segment from the sinus of Valsalva to the abdominal aorta above the renal arteries was identified by computed tomography angiography. Unfortunately, the patient died despite immunosuppressive therapy and before any surgical or endovascular intervention could be performed.,Introduction: Arterial involvement in Behcet’s disease has been previously described. We report a rare case of a large anSat, 27 Feb 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=33258Conclusions: PCI was accompanied by some improvement in left atrial deformation indices as assessed by tissue Doppler imaging. Revascularization can, therefore, improve patient outcome.,Results: Regarding changes in left trial functional parameters after PCI, those such as the strain of the septal wall and the anterior and inferior walls and the strain rate of the anterior and lateral walls significantly increased following PCI, while the strain of the lateral wall and the strain rate of the septal wall significantly decreased.,Objectives: The present study aimed to assess left atrial function by tissue Doppler parameters of strain and strain rate following percutaneous coronary intervention (PCI).,Patients and Methods: This prospective study recruited 77 consecutive patients with coronary artery disease who underwent PCI. The study end point was to assess left atrial function by regional strain and strain rate parameters before and after PCI via tissue Doppler imaging.,Background: Left atrial function can beSun, 29 Nov 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=34396Conclusions: The TSI analysis in patients with CAD may be considered an interesting parameter in addition to the conventional echocardiographic parameters during ESE.,Background: Stress echocardiography represents one of the best possible imaging choice for the diagnosis and stratification of patients with coronary artery disease (CAD). However, this imaging technique presents some limitations such as the quality of the image, high inter-observer variability, and the operator-dependent expertise. New technologies have been recently developed to provide an objective, operator-independent, and quantitative analysis of regional myocardial function.,Objectives: The aim of this study was to investigate regional myocardial dyssynchrony using tissue synchronization imaging (TSI) during exercise stress echocardiography (ESE).,Patients and Methods: The ESE and TSI analysis of left ventricular (LV) segments was performed for 30 patients with CAD previously treated with revascularization therapy (CADr group) and the resSat, 28 Nov 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=36507Conclusions: In the setting of acute left ventricular function depression in HOCM, a comprehensive differential diagnosis should be established. Treatment should be based on hemodynamic changes. After recovery, the prognosis is related to HOCM.,Case Presentation: We present a unique case where TKS occurred in a middle-aged male patient with hypertrophic obstructive cardiomyopathy (HOCM) without a clearly identifiable initial stress trigger.,Introduction: Takotsubo syndrome (TKS) is generally caused by a stressful condition, and it usually has a good prognosis after the recovery of left ventricular function. About 70% of the cases of hypertrophic cardiomyopathy may develop obstruction in the left ventricular outflow tract (LVOT), which is responsible for heart failure.Sat, 28 Nov 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=35717: The right ventricle (RV) is a complex structure with abstruse function that reveals important differences when compared to the left ventricle (LV), so it cannot be described as a simple geometric form and achromatic physiology. As an inference from this fact, in the present review, we aim to describe RV structure including the embryology, anatomy, and physiology and present a functional, hemodynamic, and imaging assessment of the normal and failing RV. So that, we conducted a thorough review based on the database sources such as MEDLINE, PubMed, Cochrane and Google scholar. No restrictions were placed on study date, study design, or language of publication. We searched all valuable and relevant information considering the anatomy, physiology, mechanics, hemodynamic and imaging evaluation of RV.Sun, 01 Nov 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=33652Introduction: Heart failure is the second most common cause of ascites after cirrhosis. There are cardiac and noncardiac etiologies of ascites, and the multimodality imaging approach is a rich tool to redefine the final diagnosis.,Case Presentation: We present a case-series where 3 patients were referred to our hospital for further hepatology assessment due to severe abdominal ascites and liver failure. Constrictive pericarditis was diagnosed in all of them. Nowadays, constrictive pericarditis is a well-known disease, but sometimes its clinical presentation may delay the treatment and worsen the prognosis. Our 3 cases had similar clinical scenarios and hemodynamic patterns when undergoing right-heart catheterization, but they had different anatomical pericardium-compromise, requiring different surgical strategies.,Conclusions: Nowadays, multimodality imaging, especially cardiac magnetic resonance imaging and cardiac computed tomography, allows us to study a wide spectrum of the same disease in terms of anatomTue, 29 Sep 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=31552Conclusions: Our case is the first report of IVUS imaging of subclavian stenosis resulting from Takayasu’s arteritis and provides insight into the pathology behind such lesions.,Introduction: Takayasu’s arteritis (TA) is a chronic, idiopathic, inflammatory disease that affects large elastic arteries, including the aorta and its main branches. No consensus exists currently on the superiority of surgery over endovascular repair (angioplasty with or without stenting) for vascular lesions in TA.,Case Presentation: A 54-year-old woman with an 11-year history of ankylosing spondylitis (AS) presented with left arm weakness and severe left arm claudication. Duplex ultrasonography of the left upper extremity showed vessel-wall edema of the subclavian, axillary, and brachial arteries. Aortic angiography demonstrated a 70 - 80% stenosis of the left subclavian artery and a long, high-grade stenotic segment of the axillary artery. Intravascular ultrasound (IVUS) of the stenotic subclavian segment showed extensive negaSat, 29 Aug 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=33809Conclusions: This is the first case report of a vanishing tumor in the right pulmonary apex.,Case Presentation: Such masses have been designated as vanishing tumors of the lung. It is extremely rare that a vanishing tumor occurs in the apex of the lung.,Introduction: In patients with acute heart failure, pleural fluid localized in an inter-pleural fissure produces a mass on chest X-ray, which mimics a tumor.Sat, 29 Aug 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=34180Patients and Methods: In 382 subjects admitted in the emergency department (ED), we evaluated maximal (Volmax) and minimal (Volmin) LA volumes and LA emptying fraction (LA-EF), from RT-3D images, with a semiautomated border detection program. A follow-up was performed in order to evaluate all-cause mortality and new hospital admission for cardiovascular events.,Objectives: Aims of this study were: 1) to evaluate feasibility of RT-3D echocardiography for LA evaluation in an acute care setting and in a population including a majority of critically ills; 2) to evaluate correlation between two-dimensional (2D) and RT-3D echocardiographic LA quantitative evaluation; 3) to assess clinical consistency and prognostic value of LA measurements obtained from RT-3D images in subjects without CV diseases and in patients with AF and CHF, evaluated in the acute phase of the disease.,Results: The correlation between measures obtained from 2D and 3D was good (LA Volmax: r = 0.896, P < 0.001; Volmin: r = 0.906, P < 0,001Sat, 29 Aug 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=34647Patients and Methods: We evaluated radiation exposure from initial and downstream testing in a prospectively collected, matched cohort evaluated for CP in the emergency department (ED) with either CCTA compared with usual care over a median follow-up of 19.6 months. Effective radiation dose was calculated using published conversion factors.,Results: Prospective, ECG-triggered acquisition using a 128-slice dual-source multidetector computed tomography (DSCT) scanner was performed in 92.9% of scans with a median effective dose from CCTA of 6.8 mSv (IQR 5.2, 9.1 mSv). CCTA cohort patients were more likely to undergo cardiac testing with exposure to radiation (P < 0.001); however, the median effective dose in patients exposed to radiation from cardiac testing was significantly lower in the CCTA cohort (7.1 mSv vs. 11.8 mSv, P < 0.001). Fewer patients in the CCTA cohort had additional non-cardiac thoracic imaging radiation exposure (40.8%) compared with usual care (92.8%). Total radiation exposure from any sSat, 29 Aug 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=30490Conclusions: Mortality from papillary muscle rupture remains elevated. Survival largely depends on the early surgical repair or the replacement of the mitral valve.,Case Presentation: A 71-year-old woman presented to an outside hospital complaining of chest pain and shortness of breath. An electrocardiogram was obtained and revealed depression of the ST segments from leads V1 to V4. Troponin I was elevated at 3.0 ng/mL. She was transferred to our facility for a higher level of care. She was found in cardiogenic shock at arrival. A bedside echocardiogram was ordered, which demonstrated papillary muscle rupture with severe mitral regurgitation. A coronary angiogram followed, which diagnosed severe three-vessel disease. After the insertion of an intra-aortic balloon pump, she was transferred emergently to the surgical suite for mitral valve replacement and revascularization. The operation was uneventful. She was discharged to a rehabilitation center after approximately 1 month of hospital stay.,Introduction: TheSun, 23 Aug 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=33216Objectives: Our aim was to study the relation between VAC and the parameters of myocardial mechanics using three-dimensional speckle-tracking echocardiography (3DSTE).,Patients and Methods: We studied 68 normal participants (mean age, 35 ± 12.2 y; 36 [53%] males). VAC was measured by the ratio of arterial elastance (Ea) to ventricular elastance (Ees). The peak systolic value of longitudinal strain (LS), circumferential strain (CS), radial strain, three-dimensional global strain (3DGS), apical rotation, torsion, and twist and their time to peak were calculated.,Results: Almost all deformation indices were higher in the women than in the men. LS (r = -0.41, P < 0.01), twist (r = 0.26, P < 0.03), rotation (r = 0.41, P < 0.01), and 3DGS (r = - 0.39, P < 0.01) were associated with age. Although significant associations were found between VAC and Ea or Ees in the men and women, no relation was found between Ea and Ees in both sexes (r = 0.07 in men and r = 0.08 in women). Indeed, VAC had a stronger assSat, 22 Aug 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=22268Conclusions: According to our multimodality imaging approach, hypertrophic cardiomyopathy was the most probable diagnosis.,Case Presentation: We describe a 73-year-old woman referred to us for consultation because of a giant negative T wave on her electrocardiography. Echocardiography revealed diffuse severe hypertrophy associated with hypertrophied anterolateral papillary muscles with a bifid head and with extensive wall insertion into the apicolateral segment. Three-dimensional echocardiography and cardiac magnetic resonance confirmed these data. Importantly, automated function imaging determined the global longitudinal strain at -10.2%.,Introduction: Multimodality imaging can help rule in/out the diagnosis of hypertrophic cardiomyopathy (HCM) in patients with significant left ventricular (LV) hypertrophy.Sat, 23 May 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=26728: Acute myocardial infarction can culminate in sudden cardiac death due to cardiogenic shock and ventricular fibrillation, and also rarely due to cardiac rupture. We present a case of post-infarction myocardial rupture after thrombolytic therapy diagnosed with transthoracic echocardiography and treated with direct closure and coronary artery bypass grafting.Sat, 23 May 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=28112Conclusions: These findings emphasize the potential clinical benefits of therapeutic procedures such as cardiac resynchronization therapy (CRT) or apex-sparing volume-reduction surgery in DCM. A better definition of the role and implications of reverse apical torsion in DCM and its importance and effectiveness in making therapeutic decisions like CRT implantation requires further studies.,Case Presentation: The patient was a 56-year-old woman, who referred to our clinic with complaints of dyspnea on exertion of 2 years’ duration. By the time of her referral, the patient’s dyspnea had exacerbated and reached New York Heart Association (NYHA) functional class III,Introduction: We describe a 56-year-old woman with dilated cardiomyopathy, whose clinical assessment, including two-dimensional echocardiography, demonstrated a spherical left ventricular geometry with severe left ventricular enlargement and dysfunction as well as reverse apical rotation. Left ventricular twist and torsion were evaluated via echocaSat, 23 May 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=28932Background: Motion artifacts that degrade image quality of coronary CT angiography (CCTA) in patients with high heart rates may be reduced with specific automatic motion correction algorithms (AMC).,Conclusions: CCTA image quality improves significantly with AMC in patients with high heart rates and reduces the proportion of non-diagnostic examinations.,Results: Mean heart rate during CCTA was 61 ± 8 bpm. CCTA quality improved significantly in the RCA (good-or-excellent in 11/17 AMC vs. 5/17 CR, P = 0.018) and LAD (15/17 vs. 7/17, P = 0.031). Non-diagnostic CCTA in the RCA, LM, LAD, and LCX reduced from 16/68 (CR, 24%) to 7/68 (AMC, 10%). Significant motion correction was observed at low (≤ 60 bpm; P = 0.008), intermediate (61-70 bpm; P < 0.001), and high heart rates (> 70 bpm; P = 0.021). Inter-reader agreement was good. (inter-class-correlation, 0.762).,Patients and Methods: CCTA images (clinical single-source-64-slice-CT system) of 17 consecutive patients with heart rates exceeding 55 bpm were recSat, 23 May 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=29470Conclusions: The prevalence of undiagnosed IHD in the HD patients was considerable. We, therefore, suggest that IHD be assessed in HD patients, especially those at high risk due to positive family history of CAD, hypertension, left ventricular hypertrophy, diabetes mellitus, Kt/V < 1.2, low ferritin levels, and high levels of intact parathyroid hormone.,Results: Sixty-nine HD patients were studied using dipyridamole MPI with Tc 99 m sestamibi. The mean age, body mass index, and mean duration of HD were 52.1 ± 13.8 years, 21.23 ± 4.79 kg/m2, and 48.2 ± 34.9 months, respectively. The patients were divided into two groups based on MPI: IHD-positive group (21.7%) and IHD-negative group (78.3%). IHD was more prevalent in the patients with diabetes mellitus, hypertension, positive family history of CAD, low HD adequacy index (Kt/V < 1.2), left ventricular hypertrophy, high intact parathyroid hormone levels, electrocardiographic abnormalities, and low ferritin levels. A statistically significant Sat, 23 May 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=30009Conclusions: Silent ventricular systolic dysfunction was more common in the patients with SLE than in the control group. Newer echocardiographic techniques such as two-dimensional STE provide an earlier chance for the detection of subclinical LV systolic dysfunction. Our findings were independent of the traditional risk factors.,Results: The mean duration of SLE was 5.5 ± 3.4 years in our patients. No significant difference was found between the two groups concerning the LV and left atrium size, LV ejection fraction, right ventricular (RV) systolic function, RV and LV diastolic function, and pulmonary artery pressure. The LV global longitudinal strain was less in the SLE patients (-18.56 ± 2.50% vs. -19.89 ± 1.94%; P = 0.028). The LV mass was greater, though not statistically significant, in the SLE patients (111 ± 29.54 g vs. 104.37 ± 27.39 g; P = 0.468). The interventricular septal diameter was thicker in the SLE patients (0.79 ± 0.15 cm vs. 0.77 ± 0.10 cm; P = 0.046).,Patients and Methods: This caseSat, 23 May 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=21211Case Presentation: We present a case with a typical picture of myocarditis but normal echocardiographic findings, the diagnosis of which was confirmed by cardiac MRI.,Discussion: In particular, cardiac MRI data are useful in borderline cases or in the presence of discrepancy between clinical picture and echocardiographic results. ,Introduction: The diagnosis of myocarditis based on a spectrum of findings, including symptoms, clinical examination, electrocardiography, biomarkers, and echocardiography, can be non-specific. Cardiac magnetic resonance imaging (MRI), has become the primary noninvasive technique in patients with suspected myocarditis in some countries.Fri, 20 Feb 2023 03:30:00 +0330http://cardiovascimaging.com?page=article&article_id=21751Conclusions: Trauma induced by the tip of the catheter at the contact location with the LV wall in a patient with mild hypercoagulable state accounted for intracardiac thrombosis formation and its embolization to the brain and intestines.,Introduction: Coronary angiography can be complicated by some major complications such as stroke. ,Case Presentation: We describe a patient who presented with hemiparesia. He had undergone coronary angiography on his right and left coronary arteries as well as his left ventricle (LV) via the radial artery access 10 days earlier using a 6-French Tiger catheter. Transthoracic echocardiography showed a large (36 × 25 mm) inhomogeneous mobile mass attached to the apicoseptal LV segment. His serum protein S was low (60% [normal = 77 - 140%]), while his protein C was normal and lupus anticoagulant was negative. During hospitalization, he developed severe abdominal pain, for which mesenteric ischemia was diagnosed. First, he underwent surgery for the resection of the infarcted intFri, 20 Feb 2023 03:30:00 +0330http://cardiovascimaging.com?page=article&article_id=22787Introduction: The term hydropneumopericardium describes the simultaneous accumulation of fluid and gas in the pericardial sac. This condition is mostly caused by primary infiltrative lesions from the adjacent organs, pericardial infections, or trauma and is a very rare situation, usually with favorable outcomes.,Case Presentation: We describe a female patient with Lutembacher’s syndrome complicated by cardiac tamponade. After surgical treatment, she developed iatrogenic hydropneumopericardium, which was treated conservatively.,Conclusions: Iatrogenic hydropneumopericardium can be managed conservatively with supportive measures, and most of these cases resolve spontaneously if they are not large and destabilizing.Fri, 20 Feb 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=24305Conclusions: Large-scale studies on the healthy black African population could assess the relationship between diastolic dyssynchrony and changes in myocardial performance related to racial differences.,Results: The frequency of some dyssynchrony markers was similar to that of other studies. The difference between maximal time-to-peak systolic velocity and minimal time-to-peak systolic velocity was correlated with age and was higher among women. The prevalence of diastolic dyssynchrony was higher in black African subjects.,Patients and Methods: Fifty healthy black African were enrolled consecutively over a period of 3 months. Time-to-peak systolic velocities (TS) and Time-to-peak early diastolic velocities (TE) were measured at the four basal segments of left ventricle. Five dyssynchrony markers were assessed: difference between maximal time-to-peak systolic velocity and minimal time-to-peak systolic velocity, time between septal time-to-peak systolic velocity and lateral time-to peak systolic velocity, standFri, 20 Feb 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=26377Conclusions: The vibratory innocent murmur is associated with the presence of left ventricular false tendon and higher left ventricular outflow tract velocity. The presence of the left ventricular false tendon was somewhat associated with decreased early diastolic myocardial velocity. Normal left ventricular systolic and diastolic function can be used as a reassurance in cases with the vibratory innocent murmur.,Results: The left ventricular false tendon was present in 84% of cases and 22% of controls (P < 0.001). Left ventricular outflow tract velocity was significantly higher in cases than in controls (P < 0.001). Early diastolic myocardial velocity at the base of the interventricular septum was lower in cases with false tendon than those without false tendon (P = 0.048). No significant difference was found regarding ascending aorta diameter, cardiac output and ejection fraction between the two groups. Left ventricular diastolic function was normal in all cases and controls.,Background: Vibratory innoFri, 20 Feb 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=26751Conclusions: LV twist, torsion and untwist and also rate of them are significantly impaired in DCM and this impairment is well-related to LV global systolic and diastolic dysfunction. VVI is a new noninvasive technique that can be used to evaluate LV torsional parameters.,Results: LV twist value (5.54 ± 1.94° in DCM VS. 11.5 ± 2.45° in control group) and also LV torsion (0.71 ± 0.28°/cm in DCM VS. 1.53 ± 0.42°/cm in control group) were significantly decreased in DCM patients compared with normal group (P < 0.001 for both); also, the twisting rate was notably lower in DCM vs. control (38.68 ± 14.43°/s in DCM vs. 75.88 ± 17.25°/s in control; P < 0.001) and also untwisting rate (36.28 ± 13.48°/s in DCM vs. -73.79 ± 24.45°/s in control; P < 0.001), However normalization of these times for systolic duration or LV length creates different values.,Background: Velocity vector imaging (VVI) is a new echocardiography method to assess myocardial deformation in two dimensions.,Objectives: In thisFri, 20 Feb 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=24391Conclusions: The cardiac grafts at 5 months' post-HTx follow-up were characterized by normal LV dimensions and EF. Also, RV dysfunction and tricuspid regurgitation were frequent findings, but they were not associated with the clinical signs of congestive heart failure, morbidity, and mortality in the majority of our patients.,Background: In patients with advanced heart failure, significant improvement in pharmacological and non-pharmacological treatment strategies has conferred better survival rates and quality of life.,Objectives: This is a report on echocardiographic findings in heart transplantation (HTx) patients in their first 5 postoperative months.,Patients and Methods: Twenty patients undergoing HTx between September 2009 and July 2010 whose clinical and echocardiographic findings had been registered monthly for 5 months after HTx were enrolled.,Results: Eleven males and five females at a mean age of 33 years [range = 17-58 years] were enrolled in the study. The mean of the left ventricular ejectThu, 27 Nov 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=19700Discussion: The reason is that we assess the relative and not absolute differences of the tracer uptake in this imaging modality. There may be other findings on MPI images which could help us overcome this pitfall, including detecting wall motion abnormalities, lung uptake of the tracer, or transient ischemic dilation. Another important issue is the ECG changes during exercise stress testing, which could point to a more extensive coronary artery disease than the one detected on MPI images alone.,Case Presentation: A 67-year-old man underwent exercise electrocardiography (ECG)-gated single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) for evaluating his mild dyspnea on exertion (New York Heart Association class I). Images showed inducible ischemia of severe intensity in the interior walls and moderate intensity in the apicoseptal and anteroseptal segments, but exercise stress to induce coronary hyperemia revealed marked ST-segment depressions in low heart rates and the patient Sun, 16 Nov 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=21344: Valvular heart disease is a considerable finding in the antiphospholipid antibody syndrome (APS). The involvement of the mitral and aortic valves is more common in the form of leaflet thickening or aseptic verrucous vegetations called the Libman-Sacks endocarditis. In addition to the detrimental effects of endocarditis on the valves, it can lead to serious thromboembolic complications. Here we report our experience with a young woman, who had a history of transient ischemic attack 2 months earlier and referred to us due to severe vaginal bleeding. On echocardiography, several irregular masses were observed on the atrial side of both mitral valve leaflets. On rheumatologic work-up, she was found to have positive anticardiolipin IgG and lupus anticoagulant. During hospitalization, the patient suffered thrombotic stroke and computed tomography (CT) scan showed a parietal lobe ischemic lesion.

Ventricular septal aneurysms can rarely develop from an interventricular septal (IVS) defect in adults. We describe a 47-year-old man with an aneurysm in the IVS growing towards the right ventricle, which was confirmed by cardiac computed tomographic angiography and was missed by echocardiography.Wed, 12 Nov 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=19863Discussion: There are other causes of dilated cardiomyopathies which could be transient like peripartum cardiomyopathy. The development of biventricular mural thrombi is rare, and it mainly increases the risk of embolization in the systemic and pulmonary circulations.,Case Presentation: We present two case reports of post-myocardial infarction sequel leading to ischemic cardiomyopathy and peripartum cardiomyopathy leading to biventricular mural thrombi formation and provide a brief review of literature regarding their etiopathogenesis and management.,Introduction: The combination of the aging of the population and improved survival after acute myocardial infarction has created a rapid growth in the number of patients currently living with chronic heart failure, with a concomitant increase in morbidity and mortality.Wed, 12 Nov 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=22232Conclusions: It seems that severe PAH aggravates the RV function more severely.,Results: Significant tricuspid regurgitation was more prevalent in the PAH group than in the PS group (61% vs. 18.5%; P < 0.001). The abnormalities in the RV myocardial performance index, RV areas, and RV fractional area change were significantly more robust in the PAH group (all Ps < 0.05) despite the higher net RV systolic pressure in the PS group as compared to the PAH group (121 ± 39 vs. 88 ± 26 mmHg; P < 0.001).,Background: Some studies have evaluated the right ventricular (RV) function in volume-overload and pressure-overload conditions and have always categorized pulmonary arterial hypertension (PAH) in the latter group. However, PAH and pulmonary stenosis (PS) are two frequent diseases, both resulting in the RV pressure overload.,Objectives: The aim of this study was to evaluate the RV response to two causes of the RV pressure overload: severe PAH and PS.,Patients and Methods: Eighteen patients with PAH at a meTue, 11 Nov 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=22903Background: Differentiating ischemic from nonischemic cardiomyopathy is important both prognostically and therapeutically, although it may be difficult clinically.,Objectives: We aimed to determine the diagnostic power of Cardiogoniometry (CGM) in the differentiation of the ischemic from the nonischemic etiology of left bundle branch block (LBBB).,Patients and Methods: We studied 37 patients with LBBB on the electrocardiogram (ECG) and left ventricular ejection fraction (LVEF) < 30%. All of them underwent coronary angiography, and 33 patients were included. Eighteen patients were categorized as the ischemic cardiomyopathy group, and 15 patients with normal coronary angiography were assigned to the nonischemic cardiomyopathy group. Then, CGM parameters were studied and compared between the two groups.,Results: Both ischemic and nonischemic cardiomyopathy groups were similar in age, LVEF, weight, height, and body mass index. Interestingly, there were no significant differences in the average value of the 40 Fri, 05 Sep 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=20708Conclusions: Compared to Iohexol and Iopamidol, Iodixanol use was associated with a lower patient perception of heat and lower HR while maintaining similar contrast-to-noise and signal-to-noise ratios.,Results: Baseline HR was similar across the patients assigned to Iohexol, Iopamidol, and Iodixanol (65.3 ± 9.7, 66.9 ± 10.9, and 65.3 ± 13.3, respectively; P = NS). Compared to Iohexol and Iopamidol, Iodixanol use was associated with lower HR at the time of image acquisition and immediately after CCTA (53.2 ± 8.0 bpm, 56.3 ± 7.8 bpm, and 56.8 ± 6.5 bpm; P = 0.069 and P = 0.032). A greater proportion of patients achieved HR ≤ 55 beats per minute (bpm) with Iodixanol (63%) than with Iohexol (42%; P = 0.025) and Iopamidol (39%; P = 0.011). As was expected, Iodixanol (2.34 ± 2.02) was associated with a lower perception of heat than Iohexol (6.13 ± 1.89; P < 0.001) and Iopamidol (5.22 ± 2.10; P < 0.001). Image quality was similar in all three groups.,Objectives: The aim of the study was to compare tTue, 05 Aug 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=20735Conclusions: This study indicated that the RV systolic strain and strain rate can be used to detect early RV systolic dysfunction in SSc patients without pulmonary hypertension. These parameters may be useful for the provision of a more adequate management of SSc patients.,Results: In the SSc patients, the RV strain (- 19 ± 10 vs. - 25 ± 4 %; P = 0.004) and the systolic strain rate (- 1.3 ± 0.5 vs. - 1.5 ± 0.3, s-1; P = 0.03) were significantly lower than those in the control group.,Objectives: The aim of this study was to assess strain-based measures of the RV systolic function in patients with SSc without pulmonary hypertension.,Materials and Methods: Thirty-eight consecutive SSc patients (mean age = 48.1 ± 13 years) with normal pulmonary artery pressure and left ventricular ejection fraction and 27 healthy subjects (mean age = 53.2 ± 10 years) were investigated. The RV systolic strain and strain rate were assessed using standard echocardiography with tissue Doppler imaging (TDI) and compared with theTue, 05 Aug 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=20737Conclusions: Despite the widespread use of 2D LVEF and its good agreement with ventriculography, strain analysis seems to be more reliable as a quantitative tool for ventricular assessment.,Results: The LVEF values obtained by the two methods of ventriculography and echocardiography were not significantly different. The highest correlation regarding the echocardiographic LVEF was obtained in the angiographic right anterior oblique view (P < 0.001, r = 0.95). There was a good agreement as regards the biplane LVEF between 2D echocardiography and ventriculography (-0.5 ± 13.27; CI of 95%). The GLS showed a significant correlation with the estimated EF in both methods, the highest being with the Biplane Simpson method (r = -0.84; P < 0.001). Linear regression was used to obtain the formula for estimating the 2D LVEF from the GLS [LVEF = 2.53 (GLS) + 10.48]. The GLS values ≥ -21.7% and≤ -11.7% were consistent with normal and severe global LV systolic dysfunction, respectively.

We demonstrate the use of several noninvasive imaging modalities along with pathology confirmation for the definitive and comprehensive diagnosis of a cardiac angiosarcoma, a rare entity by itself.,Conclusions: With the increasing availability of noninvasive imaging techniques, the diagnosis of angiosarcomas can be made at earlier stages. If angiosarcomas are left untreated, their prognosis is very poor. Therapeutic options include surgical excision, chemotherapy, radiation therapy, and heart transplantation or a combination of these.Sun, 25 May 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=19681Introduction: Dilated cardiomyopathy (DCM) is the leading cause of heart failure and arrhythmia.,Case Presentation: A 47-year-old male, diagnosed with dilated cardiomyopathy, died due to heart failure. During the screening of his family members, his 17-year-old daughter and 9-year-old son also had dilated cardiomyopathy. Another daughter had died suddenly at the age of 12 years.,Conclusions: We herein describe 3 patients with dilated cardiomyopathy developing in the father, daughter, and son of the same family and justify the importance of the screening test as an important tool for identifying families affected by familial dilated cardiomyopathy.Sat, 24 May 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=20628Conclusions: These studies will enable physicians to diagnose and follow up many cardiac diseases when this software is interfaced within echocardiographic machines.,Results: Myocardial fibers initiate from the posterior basal region of the heart, continue through the left ventricular free wall, reach the septum, loop around the apex, ascend, and end at the superior-anterior edge of the left ventricle.,Background: How can mathematics help us to understand the mechanism of the cardiac motion? The best known approach is to take a mathematical model of the fibered structure and insert it into a more-or-less complex model of a cardiac architecture.,Objectives: We provide a new mathematical tool by introducing the notions strains, which are two-by-two and three-by-three matrices.,Materials and Methods: Using motion and deformation echocardiographic data, force vectors of myocardial samples were estimated by MATLAB software, interfaced in the echocardiograph system.

Enhanced external counter pulsation (EECP) offers an alternative palliative and possibly therapeutic option for these patients. EECP achieves this by inducing hemodynamic effects much similar to those of the intra-aortic balloon pump.,Objectives: We sought to further evaluate these therapeutic effects, especially on the basis of echocardiographic data.,Patients and Methods: Thirty-two patients who had severe refractory angina despite full anti-ischemic medication and were poor candidates for invasive procedures were evaluated. After undergoing 35 sessions of EECP, the patients were followed up for 6 months for adverse events, change in quality of life, severity of the remaining symptoms according to the Canadian Cardiovascular Society (CCS) classification, and echocardiographic changes.,Results: After receiving standard EEThu, 22 May 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=18786Introduction: The Eustachian valve (EV) remnant, when present in adults, is usually rudimentary. However, in echocardiographic examinations, it may appear as a mobile long structure in the right atrium, and it rarely protrudes into the right ventricle. When it is quite large, the EV remnant could be misdiagnosed as a right atrial tumor, thrombus, or vegetation.,Case Presentation: An 83-year-old patient was referred to the surgical ward for the excision of a gastric adenocarcinoma. In the course of preoperative assessment, transthoracic echocardiography showed a right atrial mobile filamentous mass that was protruding into the right ventricle. Differential diagnosis included a tumor or thrombus. After a precise evaluation through multiple views, the mass was demonstrated to be a giant EV, 7.3 cm in length.,Conclusions: The giant EV remnant can persist in adults and is often diagnosed incidentally via echocardiography. Transthoracic echocardiography is a reliable noninvasive method for the diagnosis of the EV rWed, 21 May 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=19641Conclusions: In most cases, the conus artery can be visualized in cardiac CT. A description of the conus artery should be a part of the standard clinical coronary CT angiography description.,Objectives: To examine whether it is possible to visualize the conus artery in multi-slice computed tomography (CT).,Patients and Methods: In 79 consecutive patients (aged 56 ± 12.9 years; 13 women), 64-slice CT was performed due to a suspicion of coronary artery disease. The standard protocol for scanning with retrospective gating was used for all the patients.,Results: It was possible to visualize the conus artery in coronary CT angiography in 64 (81%) patients. The course of the conus artery in the right ventricle was commonly in the outflow tract direction. The conus artery was visualized at a distance of 33.2 ± 16.3 mm. The average diameter of the conus artery was 2.3 ± 0.8 mm. The conus artery most frequently originated from the first segment of the right coronary artery (53%) and directly from the aorta (37.9%).Tue, 20 May 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=19196Background: Evaluation of the accuracy and performance of sonography units needs tissue-mimicking phantoms. These phantoms play an important role by simulating soft tissues, obviating the need to experiment on humans or animals.,Objectives: To present a simple sonographic phantom for quality control and training purposes.,Materials and Methods: The presented phantom consists of a two-part Plexiglas box. The larger part is filled with a mixture of ethanol (9.5 ± 0.25%) in distilled water and a solution of sodium nitrite (0.1 M) to prevent rusting. The second part is filled with a combination of 3.85% by wt. % agar, and 50 g/L of powdered graphite as the background material. In this study, chrome-plated electric guitar strings, 0.52 mm in diameter, were used. Several objects were considered as tissue-equivalent material, and their images were obtained at different times. Criteria for the selection of suitable objects comprised similarity between the obtained image and the corresponding tissues in the human bodThu, 15 May 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=17369: Transcatheteraortic valve implantation, first introduced in 2002, has been established as an alternative modality for patients deemed not suitable for open-heart surgery. The anatomical vicinity of the atrioventricular node and the His bundle to the non-coronary and rightcoronary aortic cusps predisposes patients to conduction abnormalities in case of severe calcification or mechanical trauma during valve implantation. However, the two evaluated valves (CoreValve and Edwards SAPIEN valve) have different rates of these complications, mainly driven by their respective geometry.,: Currently, there is ongoing evaluation of the true rate of conduction disorders and their clinical relevance or durability. The initial experience of fatal outcomes with conduction disorders such as complete atrioventricular block has increased the rate of subsequent pacemaker implantation up to 50%. However, prophylactic pacemaker implantation is associated with several possible complications. Thus, there is a need for further data Sun, 13 Apr 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=16081Conclusions: In our subjects, with a normal value of LA size, the effect of hypertension on LA reservoir function was independent of age, sex, heart rate, left ventricular mass index, and left ventricular ejection fraction. Additionally, heart rate independently correlated with reduced TVI and SRI parameters in the patients with hypertension.,Background: Patients with hypertension are at risk of structural and functional changes in the left atrium (LA). There are only a few studies on the impact of hypertension on LA function, especially in hypertensive patients with a normal LA size. We, therefore, designed this study to evaluate LA function in patients with a normal LA size via deformation imaging.,Objectives: We assessed regional longitudinal strain rate imaging (SRI) profiles along with tissue velocity imaging (TVI) in the LA walls to quantify LA reservoir function and explore changes in LA function in hypertensive patients with a normal value of LA size.,Patients and Methods: One hundred twenty-four subjSun, 16 Feb 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=17123Conclusions: Sm wave in TDI is prominent and significantly high in MVP syndrome. Also, our study showed some degree of diastolic dysfunction in MVP patients.,Results: Seventy-five patients (48 females) at a mean age of 26.5 ± 9.4 years and 50 individuals (32 females) at a mean age of 27.1 ± 8.3 years were enrolled in the study. As the important results of our study, Sm wave was much more prominent and much higher in the MVP group (P = 0.00); Em was lower (P = 0.00) and Am was slightly higher (P = 0.12). Furthermore, the E waves of MV inflow for the MVP and control groups were similar and E/Em was significantly higher in the MVP group (P = 0.00); taken together with a higher left atrial volume in this group, this finding revealed a relatively higher left ventricular end-diastolic pressure.,Objectives: We aimed to evaluate the findings of TDI in MVP syndrome.,Patients and Methods: Seventy-five patients with MVP syndrome and 50 normal individuals as the control group were evaluated.

A left atrial mass can be diagnosed as a thrombus by transthoracic echocardiography in the presence of the predisposing factors for a thrombus such as mitral stenosis and atrial fibrillation. The sensitivity of transthoracic echocardiography for detecting left atrial appendage thrombi is low, and only a few case reports have been described in the literature.,Conclusions: Transthoracic echocardiography was sufficient to establish the diagnosis and to decide its management.,Case Presentation: This report describes the case of a 65-year-old female with severe rheumatic mitral stenosis and chronic atrial fibrillation presenting with congestive heart failure. This patient was shown, by means of transthoracic echocardiography, to have a large immobile left atrium cavity mass (6.5 × 3.4 × 2.3 cm) and a large left atrial appendage mass (1.7 cm) identified as a thrombus.

It is associated not only with hypertension but also with other cardiac complications. Thus, the early detection of cardiac disorders is very useful.,Objectives: We sought to evaluate different echocardiographic parameters.,Patients and Methods: This cross-sectional study was done on 55 patients with OSA. The patients were divided into three groups: mild, moderate, and severe according to the apnea hypopnea index (AHI) and all underwent echocardiography. Analysis was done by SPSS 18 as well as the chi-squared and one-way ANOVA tests.,Results: The mean age of the study population was 51.16 ± 12.88 years old and 36 (65.5%) patients were male. Right Tei index mean was 0.383 ± 0.213, which was abnormal in 19.1% of the patients. Left Tei index mean was 0.378 ± 0.230 and was abnormal in 52.9% of the patients. Pulmonary artery pressure mean was 18.32 ± 8.91 and was normal in 39 (70.9%) patients.

There are different kinds of noninvasive methods to determine right ventricular function, pulmonary artery pressure, and effect of pulmonary hypertension on right ventricular function. These methods include the tissue Doppler imaging (TDI) of the tricuspid annulus and the longitudinal deformation indices of the right ventricular free wall.,Objectives: In some patients, the echocardiogram cannot help estimate pulmonary artery pressure. In this study, we evaluated the effect of pulmonary hypertension on the TDI of the tricuspid annulus and the longitudinal strain and strain rate of the basal segment of the right ventricular free wall in patients with left-sided valvular heart disease and pulmonary hypertension. Indeed, we sought to investigate whether we can guess the presence of pulmonary hypertension through the measurement of the TDI of the tricuspid annulus and the deformity indices of tSat, 04 Jan 2024 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=13858Introduction: Tetralogy of Fallot (TOF) in the absent of pulmonary valve is a rare congenital anomaly (3%of TOF patients).,Case Presentation: We are presenting an 18- year-old male with history of dyspnea on exertion and cyanosis since childhood. Despite the diagnosis of congenital heart disease, no intervention was done due to his poor socioeconomic culture. At age of 18, he referred to our center for further evaluation of heart problem. After physical examination and other diagnostic tests, our final diagnosis was tetralogy of fallot, absent pulmonary valve and double-chamber right ventricle. The absence of mature PV tissue leads to severe pulmonary regurgitation, which is often associated with significant dilatation of the pulmonary arteries. After further evaluation of main pulmonary artery, its branches and other abnormalities of the heart, total correction of tetralogy and pulmonary valve replacement was done. His post operation period was uneventful without any complication and he discharged after 10 dTue, 12 Nov 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=14289Conclusions: Results suggest that these methods cannot be interchanged, and VVI showed significantly lower LV peak twist, peak twisting rate and peak untwisting rate. However, when LV twist and LV twisting rates were normalized to LV length, values were comparable for both imaging techniques.,Results: Twist degree was significantly lower in the VVI group than in the TDI group (P = 0.008, r = 0.56). LV torsion was lower in the VVI group but was not significant. (P = 0.13, r = 0.38). Twisting rate (P = 0.004, r = 0.66) and untwisting rate (P = 0.0001, r = 0.61) were lower in the VVI group, but when timing of untwisting rate was normalized by systolic duration, there was no significant difference between the two groups (P = 0.41, r = 0.59). Similarly, when peak untwisting rate was normalized by LV length, there was a significant decline in normalized peak untwisting rate in the VVI group (P = 0.004, r = 0.62), but not in peak twisting rate normalized by LV length (P = 0.12, r = 0.42).

Rhabdomyomas are histologically benign; however, they may cause severe arrhythmia even when they are regressing.,Case Presentation: Our tuberous sclerosis patient developed arrhythmia unexpectedly while his tumors were in regression, presenting a challenge to us as to whether or not opt for surgery.,Introduction: The cardiac outcome in tuberous sclerosis patients is usually favorable, and cerebral manifestations determine the ultimate prognosis in these patients.Sun, 10 Nov 2023 00:00:00 +0330http://cardiovascimaging.com?page=article&article_id=15662Background: Echocardiography is widely used to diagnose or exclude cardiac disease. The reports on reference values based on an Asian population are limited.,Objectives: We conducted a study to determine normal values for two-dimensional, M-mode, and Doppler echocardiographic measurements and evaluate the relationship between these parameters and age and gender in a large, healthy Iranian population. ,Patients and Methods: Among a total of 400 volunteers in a cross-sectional study, 368 healthy individuals aged between 30 and 70 years [171 males at a mean age of 47.6 (9.9) and 197 females at a mean age of 47.6 (9.5)] were enrolled. Standard comprehensive transthoracic echocardiography (TTE) was performed based on the guidelines of the American Society of Echocardiography.

Statistically significant relationship between the occurrence of AF with Mitral valve annulus, LA Volume Index (LAVI) , Right ventricle function, and type of surgery (off pump or on pump) were detected in our study (P < 0.05) . There was no statistically significant relationship between the occurrence of AF and time interval of P wave to A wave onset in conventional Doppler echocardiographic study (P-A), P-A′ onset and P-A’ peak in TDI examination (P > 0.05).,Conclusions: Based on our findings, MV annulus, LAVI, RV function and on pump CABGS were independent factors related to the occurrence of AF post CABGS.

A few cases have been reported. We presented a case with hypoplastic right ventricular and multiple associated anomaly (Ventricular septal defect, atrial septal defect and pulmonary stenosis) in whom the main concern was whether biventricular repair or Fontan type surgery would be the optimal management in this patient.

Myocardial velocities, strain, and SRI profiles from the RA free wall, IAS, and LA lateral wall were calculated throughout the three cardiac cycles. Peak systolic, diastolic and time to peak were derived, and the average of the three cardiac cycles was taken into account for analysis in this study.,Results: The RA peak systolic, peak of early, and late diastolic velocities were 9.2 ± 1.6 cm/s, -9.5 ± 1.8 cm/s, Thu, 20 Jun 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=11128Patients and Methods: Forty five young female volunteer athletes were included and received different training regimens (endurance-training, strength training and concurrent groups) for a 10 week period as study intervention. Standard color Doppler echocardiography was performed for assessment of the left ventricular activity.,Results: As a result, 45 athletes ended the study training regimens. Mean of cardiac parameters was not significantly different among athletes under study before the beginning of the study training regiments. Mean of end diastolic diameter among athletes of strength-trained group had been significantly increased after receiving the study training regiments. Mean of posterior wall thickness had been significantly increased in athletes of strength and concurrent groups.

It would play an important role in pathophysiological process of the right sided heart failure in these patients.,Results: The myocardial velocities and deformational indices of RA free wall were significantly compromised in TOF patients compared with normal subjects. There was no correlation between RA function data measured by strain imaging and RV volume measured in CMR.,Patients and Method: Forty six adult patients with TOF who underwent total correction surgery in childhood and had severe pulmonary regurgitation and fulfilled the criteria of ACC/AHA guideline for PVR enrolled. The control group included 50 healthy adults with matched age and sex. Standard transthoracic echocardiography was performed on both groups which myocardial velocities and strain imaging indices were obtained from their RA free wall.,Objectives: We aimed to measure the right atrial function by this method in adultThu, 20 Jun 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=12078: Ebstein anomaly is characterized by apical displacement of the septal and posterior tricuspid valve leaflets, leading to atrialization of the right ventricle and could be diagnosed in a routine transthoracic echocardiography exam. We reported a young man with right sided heart failure symptoms who was found to have biventricular failure with suspected apical displacement of septal leaflet of tricuspid valve. For better evaluation, cardiac magnetic resonance imaging (CMR) was performed and nicely proved the diagnosis of Ebstein's anomaly with late intramyocardial enhancement of both left and right ventricles. CMR has the potential for providing information while echocardiography cannot, especially regarding the right ventricle and related myocardial problems, and Ebstein’s anomaly with decreased left ventricular (LV) systolic function.Thu, 20 Jun 2023 00:00:00 +0430http://cardiovascimaging.com?page=article&article_id=12490Conclusions: High prevalence of the increased CIMT in patients undergoing CABG highlights the significance of CIMT measurement in early diagnosis of the systemic atherosclerosis. Moreover, although Traditional cardiovascular risk factors were important they could not explain the extension and the severity of CIMT. It seems that some ultrasonographic features such as the associated carotid plaques and their characteristics provide promising clues to detect existing atherosclerosis. More importantly, avoiding the misinterpretation age-adjustment should be considered in all patients. ,Background: Coronary artery angiography is still the gold standard of choice for detection of coronary artery disease. Nevertheless, it is an invasive procedure and its complications are not uncommon. It also predisposes patients to the potential risks of contrast study and radiation,Objective: In the present report, we aimed to assess the significance of carotid intima-media thickness (CIMT) in patients undergoing coronary artery Wed, 19 Jun 2023 00:00:00 +0430
