WebFractional flow reserve (FFR) is a diagnostic technique used in coronary catheterization.FFR measures pressure differences across a coronary artery stenosis (narrowing, usually due to atherosclerosis) to determine the likelihood that the stenosis impedes oxygen delivery to the heart muscle (myocardial ischemia).. Fractional flow … WebDec 5, 2024 · Fractional flow reserve formula is FFR = Pd/Pa. 3 FFR is measured using guidewires equipped with micromanometer pressure sensors. 2 The coronary guidewires are inserted via transradial or transfemoral catheterization. 4. FFR was originally defined as the ratio of proximal and distal blood flow across the coronary stenosis.
