Abstract

Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are 2 methods used to detect hemodynamically significant lesions and guide revascularization. Discrepancies between FFR and iFR values can complicate revascularization decisions. We present a series of 6 cases with discrepant FFR and iFR results. Among them, 5 were men, 5 had lesions in the right coronary artery, and one had left anterior descending disease, with an average age of 61.7 ± 11.1 years. All patients were iFR negative (mean iFR 0.94 ± 0.02) and FFR positive (mean FFR 0.75 ± 0.04). Consequently, all patients underwent revascularization.
