WebCleared by the FDA in March 2014, instant wave-free ratio (the iFR modality) (Volcano Corporation) is an easier method to achieve physiologic assessment than fractional flow reserve measurement. iFR assesses whether a stenosis is causing a limitation of blood flow in coronary arteries with subsequent ischemia without the requirement of running … WebPurpose: Quantitative flow ratio (QFR) is a recently developed image-based index for the assessment of borderline coronary artery disease. We sought to investigate a correlation …

Web14 dec. 2024 · This measure was called the instantaneous wave-free pressure ratio (iFR). iFR was found to generally correlate to FFR (80%–85% concordance) 1 and coronary flow reserve (with a higher concordance than FFR), 2 and to be clinically noninferior to FFR in 2 large randomized trials with relatively low-risk ischemic heart disease patients, DEFINE … Webthat show an 81% concordance between iFR and FFR values in LM stenosis using an iFR cuto of 0.89 and FFR cuto of 0.80 [5]. Kaplan-Meir analysis in more recent studies using iFR showed MACE-free survival rates of 90.8% in the deferred group and 85.4% in the revascularized group (p = 0.26) at 4 years post-decision.
