Webb30 juni 2015 · It is difficult to estimate volume from 2D echo, because the algorithms for measuring it are inaccurate. The Simpson method is one such beast, and it is frequently wrong. You need good pictures to estimate the endocardial border, and you need to be sure you have the left ventricle in its widest crossection, both in systole and diastole. Webb1 dec. 2015 · Using echocardiography, LAV calculation can be derived from measurements of diameters (cube method, ellipsoid method) or from measurements of areas (biplane Simpson's and A/L methods). In the present study, we show that each method provides significantly different measurements in both healthy volunteers and patients.
