Diagnostic Performance of the Instantaneous Wave-Free Ratio: Comparison With Fractional Flow Reserve [Coronary Physiologic Assessment and Imaging]

Conclusions— The present meta-analysis shows that iFR significantly correlates with standard FFR and shows a good diagnostic performance in identifying FFR-positive coronary stenoses. Finally, iFR and FFR have similar diagnostic efficiency for detection of ischemia-inducing stenoses when tested against a third comparator.
