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).

WebFeb 4, 2022 · CT fractional flow reserve (FFR CT) is a physiologic simulation technique that models coronary flow from routine coronary CT angiography (CTA). To evaluate lesion-specific ischemia, FFR CT is measured 2 cm distal to a stenotic lesion. FFR CT greater than 0.8 is normal, 0.76–0.8 is borderline, and 0.75 or less is abnormal.

https://www.ncbi.nlm.nih.gov:443/pmc/articles/PMC4558352/

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.
