WebFractional flow reserve (FFR) is a physiological index of the severity of a stenosis in an epicardial coronary artery, based on the pressure differential across the stenosis. Clinicians are increasingly relying on this method because it is independent of baseline flow, relatively simple, and cost effective. The accurate measurement of FFR is predicated on maximal … WebThe void fraction, , depends on the prevailing flow patterns. The homogeneous void fraction model over-predicts the kinetic energy, while the selected separated flow models under-predict the kinetic energy. Thus an effective void fraction was recommended by modifying the homogeneous model.

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 ...
