Normal Echocardiographic Values of 368 Iranian Healthy Subjects

Anita Sadeghpour, Mohammadreza Shahrabi, Hooman Bakhshandeh, Nasim Naderi

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. The normal limits are presented as mean (SD) and are also indexed to body surface area (BSA).

Results: There was no significant difference between the men and women regarding left ventricular (LV) ejection fraction (57.97% vs. 57.99%). The mean of LV end-diastolic diameter (LVEDD), LV end-systolic diameter (LVESD), interventricular septum (IVS), posterior wall (PW) thickness, and right ventricular diastolic diameter (RVDd) was significantly greater in the men than in the women. However, there was an inverse relationship when LVEDD, RVDd, and left atrial (LA) diameter and area were indexed to BSA. There was no significant difference in the mean of LA area between the males and females (14.28 vs. 13.6 cm2). The LV diastolic parameters correlated negatively with age. A peakE /A velocity ratio < 1 was found in the subjects over 50 years old. The mean of all the measurements in our study was less than the reference values in the published guidelines.

Association Between Echocardiographic Indices and Post Coronary Artery Bypass Graft Surgery Atrial Fibrillation

Mehrnoush Toufan, Fariborz Akbarzadeh, Mehdi Arabmaleki

Results: The mean age of patients was 60 ± 9.9 years. 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).

Evaluation of Left Atrial Two-Dimensional Strain in Patients with Systolic Heart Failure using Velocity Vector Imaging

Maryam Esmaeilzadeh, Farveh Vakilian, Majid Maleki, Ahmad Amin, Sepideh Taghavi, Hooman Bakhshandeh

Results: A significant differences in LA volume index (LAVI) and strain were found in patients with systolic heart failure (SHF) versus normal subjects (23.8 ± 4.1 versus 57.8 ± 19.7 ml/m², P < 0.001 and 39.6 ± 10.6 versus 8.2 ± 5.3%, P < 0.001). Multivariate analysis of separate walls revealed significant inverse relationship between LA size and volume with total and regional (2-ch view) 2D strains of LA. Significant inverse relationship were also detected between pulmonary artery systolic pressure and both total LA strain (22 ± 8 versus 42 ± 10 mmHg, r = -0.4, P < 0.001) and LA strain in 2-chamber (r = -0.5, P < 0.001). A cutoff value of total average LA strain (≥ 23.28%) can differentiate normal and abnormal LA function with a sensitivity of 93% and specificity of 100% and a cutoff value of total LA strain (in average) of 17.2% can differentiate mild and moderate and severe diastolic dysfunction with a sensitivity of 100% and a specificity of 97%.

Absent Pulmonary Valve Associated With Tetralogy of Fallot and Double Chamber Right Ventricle

Shabnam Mohammadzadeh, Ali Sadeghpour Tabaei, Farhad Mirzaaghayan

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 days.
