Web2D and 3D echocardiography was performed in random order. All acquired 2D and 3D data sets were transferred to a dedicated work-station (TomTec 4D; TomTec Imaging Systems, Munich, Germany). Considering 2D data sets, end-diastolic and end-systolic LV volumes and EF were determined by semiautomatic tracing of end-systolic WebThe ejection fraction (EF) formula equals the amount of blood pumped out of the ventricle with each contraction (stroke volume or SV) divided by the end-diastolic volume (EDV), the total amount of blood in the ventricle. To express as a percentage, you would multiply by 100. So, EF = (SV/EDV) x 100. In other words, the ejection fraction is the ...
