Functional coronary assessment: instantaneous wave-free ratio and other indices

, 2018
The instantaneous wave-free ratio (iFR) is a hyperaemia-independent coronary pressure index for the physiological assessment of coronary stenoses. The underlying concept of iFR is that it quantifies the trans-stenotic pressure ratio during the wave-free ...
