Numerical Simulation of Instantaneous Wave-Free Ratio of Stenosed Coronary Artery
International Journal of Computational Methods, 2019Instantaneous wave-free ratio (iFR), an invasive index of coronary artery tree, can evaluate the functional performance of vascular stenosis without pharmacological vasodilators. The noninvasive assessment of diameter stenosis (DS) obtained from coronary computed tomography angiography (CTA) has high false positive rate in contrast to iFR.

Fractional flow reserve and instantaneous wave free ratio in 2015.
Minerva cardioangiologica, 2016In the recent years it has become apparent that angiography-based assessment of coronary artery stenosis suffers from considerable inaccuracy and pitfalls. Besides interobserver variability in assessing stenosis severity, the correlation between angiographic severity and ischemia is suboptimal.

Fractional flow reserve (FFR) is an essential tool for evaluating coronary artery disease and directing percutaneous coronary intervention (PCI). The instantaneous wave-free ratio (iFR) has been validated as a non-hyperemic alternative with less procedural complexity and adverse effects, as no pharmacological induction of hyperemia is required ...
