Title: Real-time three dimensional echocardiography in evaluation of left ventricular volume and ejection fraction in patients with aneurysm combined with myocardial infarction
Abstract: Objective:To assess the feasibility and accuracy of real-time three dimensional echocardiography(RT-3DE) in quantitative evaluation of left ventricular(LV) volume and ejection fraction(EF) in patients with ventricular aneurysm and myocardial infarction.Methods: Twenty-three patients with left ventricular aneurysm combined with myocardial infarction were examined by RT-3DE,two dimensional echocardiography Simpson's method,and M-mode Teichholz method separately.The following parameters: left ventricular end diastolic volume(LVEDV),end systolic volume(ESV),stroke volume(SV) and EF were obtained by each method and the results were compared with those obtained by left ventriculography(LVG).Results: The values of LVEDV,LVESV,SV,and EF determined by RT-3DE showed good correlations with those determined by LVG(r=0.92,0.90,0.88,and 0.91,respectively;P0.001),with the values by RT-3DE slightly smaller than those by LVG(P(0.05).) The values of LVEDV,LVESV,SV,and EF determined by Simpson's method also showed good correlations with those determined by LVG(r=0.85,0.87,0.86,0.91,respectively;P0.001),with the values by Simpson's method smaller than those by LVG(P0.05 for LVEDV and LVESV).The values of LVEDV,LVESV,SV,and EF determined by M-mode Teichholz method also showed good correlations with those determined by LVG(r=0.73,0.71,0.70,0.65,respectively;P0.05),with the values by M-mode Teichholz method larger than those by LVG(P0.05 or P0.01).Conclusion: RT-3DE is a more accurate for evaluation of LV volume and EF in patients with aneurysm combined with myocardial infarction.
