IMPLEMENTATION OF CORONARY ARTERY PHANTOM WITH ARTIFICIAL HYPEREMIA AND ANALYSIS OF PRESSURE AND FLOW VELOCITY DEPENDING ON THE DEGREE OF STENOSIS

Fractional Flow Reserve (FFR) and instantaneous wave-Free Ratio (iFR) are the two most commonly used coronary pressure based indices of physiological stenosis severity. The goals of this study are to estimate the differential power of the resting pd/pa, FFR, and iFR in an experiment system
