Multimodality Imaging in Hypertrophic Cardiomyopathy Associated With Anomalous Hypertrophied Papillary Muscles: A Case Report

Ikram Kammoun, Lemone Houchinne, Sonia Marrakchi, Wael Ben Amara, Zied Ibn Elhaj, Souha Mokrani, Faouzi Added, Salem Kachboura

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%.

Reverse Left Ventricular Apical Rotation in Dilated Cardiomyopathy

Zahra Ojaghi-Haghighi, Azin Alizadehasl, Arash Hashemi

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 echocardiography with velocity vector imaging; the patient was found to have reverse rotational movement. We hereby address these issues from an echocardiographic point of view.

Improved Image Quality of Coronary CT Angiography Using Automatic Motion Correction

Bernhard Bischoff, Lucas L Geyer, Maximilian F Reiser, Ullrich G Mueller Lisse

Patients and Methods: CCTA images (clinical single-source-64-slice-CT system) of 17 consecutive patients with heart rates exceeding 55 bpm were reconstructed with both CR and AMC during the individually best-suited phase of the cardiac cycle. Two independent readers who were blinded to the reconstruction algorithm scored image quality of each coronary artery segment (AHA 15-segment-model; 1: non-diagnostic - 4: excellent). In case of disagreement a third blinded reader assigned a final score. Two-tailed statistical tests (Wilcoxon-matched-pairs, Pearson-correlation) were significant at P < 0.05.

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).

Comparison of Echocardiographic Variables Between Systemic Lupus Erythematosus Patients and a Control Group

Hoorak Poorzand, Seyedeh Zahra Mirfeizi, Aida Javanbakht, Hedieh Alimi

Patients and Methods: This case-control study was conducted in 45 SLE patients (88% female; mean age = 31.2 ± 8.2 years) and 25 healthy controls (87% female; mean age = 30.3 ± 7.7 years), matched in terms of age and sex. Both groups had no clinical signs and symptoms of cardiac problems or risk factors for cardiovascular diseases. Both SLE and control groups underwent echocardiography for the assessment of the ventricular function and the sizes and diameters of the chambers. Two-dimensional STE was used for the measurement of the left ventricular (LV) global longitudinal systolic strain.

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).

Detection of Undiagnosed Ischemic Heart Disease in Hemodialysis Patients Using Myocardial Perfusion Imaging

Marzieh Nikparvar, Elham Boushehri, Hamid Reza Samimagham, Maryam Amrollahi, Tasnim Eghbal Eftekhaari

Patients and Methods: In this cross-sectional descriptive study, HD patients who met the inclusion criteria were selected. Demographic, clinical, and paraclinical data were obtained via interviews and medical records. Bedside electrocardiography, resting echocardiography, and nuclear MPI with dipyridamole were done. The data were analyzed using descriptive statistical methods for detecting the prevalence of undiagnosed IHD in the HD patients. The chi-square test and the independent t-test were used to identify the high-risk HD patients.

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 correlation was also detected between IHD and aging (P < 0.05).
