The reasons why fractional flow reserve and instantaneous wave-free ratio are similar using wave separation analysis

BMC Cardiovascular Disorders, 2021
Background and objectives Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are the two most commonly used coronary indices of physiological stenosis severity based on pressure. To minimize the effect of wedge pressure (P wedge ), FFR

Pre-Angioplasty Instantaneous Wave-Free Ratio Pullback Predicts Hemodynamic Outcome In Humans With Coronary Artery Disease

, 2018
OBJECTIVES: The authors sought to evaluate the accuracy of instantaneous wave-Free Ratio (iFR) pullback measurements to predict post-percutaneous coronary intervention (PCI) physiological outcomes, and to quantify how often iFR pullback alters PCI ...

INSTANTANEOUS WAVE-FREE RATIO (IFR) CAN DETECT IMPROVEMENT IN CORONARY STENOSIS SEVERITY AFTER PERCUTANEOUS INTERVENTION [PDF]

Heart, 2016
Background The instantaneous wave-Free Ratio (iFR), a pressure-only adenosine-free index of coronary stenosis severity has been evaluated as a diagnostic tool in the ADVISE trial and registry. However, it is unknown whether iFR can detect improvement in stenosis significance immediately after percutaneous coronary ...
