Clinical evaluation of left ventricular function in patients with ventricular aneurysm after myocardial infarction by real-time tri-plane echocardiography

Objective To assess the accuracy of left ventricular function by real-time tri-plane echocardiography in patients with ventricular aneurysm after myocardial infarction. Methods The volumetric parameters of the left ventricle in 25 patients with ventricular aneurysm after myocardial infarction were evaluated. The left ventricular end-diastic volume (LVEDV), left ventricular end-systolic volume (LVESV), stroke volume (SV) and LVEF were measured on real time tri-plane echocardiography and two dimensional echocardiography. The results were obtained and compared with left vemtriculography. Results There were no statistically significent differences in parameters between RT Tri-plane LVEDV, LVESV, SV, LVEF and those in left ventriculography (P0.05) and there was a good correlation between the two methods (r= 0.94, P0.01). There were significent differences in parameters between 2DE LVEDV, LVESV and those in left ventriculography. There was a significant correlation between the two methods (r=0.85, P 0.01). Conclusions Real-time tri-plane echocardiography is a noninvasive and accurate method for quantitative analysis of the left ventricular function in myocardial infarction patients with ventricular aneurysm.
