Title: Comparison of Left Ventricular Volumes and Ejection Fractions Measured by Two-Dimensional Echocardiography Versus by Realtime Three-Dimensionai Echocardiography and Cardiac Magnetic Resonance in Patients With Left Ventricular Aneurysm
Abstract: Objective:To evaluate the accuracy and value of measurement of left ventricule volume and function with real time three-di- mensional echocardiography(RT-3DE)in patients with left ventrictular aneurysm. Methods:Left ventricule end diastolic volume(LVEDV),left ventricule end systolic volume(LVESV),left ventricule ejec- tion fraction(EF)before and after operation were measured with 2DE,RT-3DE and MRI. Results:Before operation,LVEDV and LVESV obtained with two-dimensional echocardiography(2DE)and RT-3DE are smaller than those obtained with MRI,LVEF obtained with 2DE and RT-3DE are more larger than those obtained with Magnetic Resonance image(MRI)(P0.05).After operation,LVEDV and LVESV obtained with 2DE are still smaller than those ob- tained with MRI(P0.05),no significant differences between those obtained with RT-3DE and MRI. Conclusion:RT-3DE can accurately measure the left ventrlcule volume and function than 2DE.But before operation,in pa- tients with left ventricular aneurysm,LVEDV and LVESV obtained with RT-3DE are still underestimated.
