Comparison of adenosine‐independent pressure indices to fractional flow reserve in stent‐jailed bifurcation side branches

This study aims to evaluate whether the high correlation and classification agreement of the instantaneous wave-free ratio (iFR) and the resting distal coronary to aortic pressure ratio (PConsecutive patients (n = 49) undergoing provisional stenting were prospectively enrolled and a physiological assessment of the J-SB (n = 51) was performed. FFR, iFR, and PBoth iFR (r = 0.75) and PAs reported for other lesion types, FFR and the adenosine-independent pressure indices iFR and P
