Instantaneous wave-free ratio (iFR) is a vasodilator-free index of coronary blood flow used for revascularization decision-making. iFR-based revascularization also had a decreased rate of adverse effects from vasodilators, shorter procedure times, and lower revascularization rates. iFR-pullback predicts post-percutaneous coronary intervention physiologic outcomes in tandem and diffuse coronary lesions. iFR may be particularly useful in patients with potential adenosine resistance, contraindications to adenosine, and multivessel or serial lesions. iFR is a useful tool both with and without fractional-flow reserve for revascularization planning.
