Instantaneous wave-free ratio and fractional flow reserve in clinical practice. [PDF]

Neth Heart J, 2018
To compare fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) measurements in an all-comer patient population with moderate coronary artery stenoses.Visual assessment of the severity of coronary artery stenoses is often discordant in moderate lesions.

Instantaneous wave-free ratio guided multivessel revascularisation during percutaneous coronary intervention for acute myocardial infarction: study protocol of the randomised controlled iMODERN trial [PDF]

BMJ Open, 2021
Introduction Recent randomised clinical trials showed benefit of non-culprit lesion revascularisation in ST-elevation myocardial infarction (STEMI) patients. However, it remains unclear whether revascularisation should be performed at the index procedure

Does the Instantaneous Wave-Free Ratio Approximate the Fractional Flow Reserve?

Journal of the American College of Cardiology, 2013
This study sought to examine the clinical performance of and theoretical basis for the instantaneous wave-free ratio (iFR) approximation to the fractional flow reserve (FFR).Recent work has proposed iFR as a vasodilation-free alternative to FFR for making mechanical revascularization decisions.
