Aim The quantitative flow ratio (QFR) is favorable for functional assessment of coronary
artery stenosis without pressure wires and induction of hyperemia. The aim of this study was …

The quantitative flow ratio (QFR) is a novel angiography-based computational method
assessing functional ischemia caused by coronary stenosis. This study aimed to evaluate …

Fractional flow reserve (FFR) has become the gold standard for evaluating coronary lesion-
specific ischemia. However, FFR is an invasive method that may cause possible …
