WebFeb 28, 2024 · Background . Left ventricular ejection fraction (LVEF) and end diastolic volume (EDV) are measured using Simpson’s biplane (SB), 3-dimensional method (3DE), and speckle tracking (STE). Comparisons between methods in routine practice are limited. Our purpose was to compare and to determine the correlations between these three … WebEjection fraction is derived from the End Diastolic Volume and End Systolic Volume estimates. It is the relation between the amount of blood expelled during each cardiac cycle relative to the size of the ventricle. It can be performed in a 2D or 3D image.
