Figure 1From: Assessment of left ventricular volumes and primary mitral regurgitation severity by 2D echocardiography and cardiovascular magnetic resonance Measurement of the ejection fraction by 2D TTE and CMR. A. The LVEF by 2D TTE was obtained by the modified Simpson’s method in the apical four- and two-chamber view. B. The LVEF by CMR was calculated by assessment of end-diastolic and end-systolic LV volumes in multiple parallel short-axis slices.Back to article page
