Web2 days ago · With regard to FFR evaluation for PCI optimization, the FFR SEARCH and TARGET-FFR studies highlighted that more than half of patients presented a suboptimal post-PCI FFR (FFR ≤ 0.90) [76,77]. In addition, an inverse relationship between post-PCI FFR and clinical events was shown in a previous meta-analysis [ 78 ]. Fractional 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 … See more During coronary catheterization, a catheter is inserted into the femoral (groin) or radial arteries (wrist) using a sheath and guidewire.
