New Pressure Index Is FFR minus Adenosine

A new pressure-based index to measure the severity of coronary lesion stenosis without adenosine compared favorably to fractional flow reserve (FFR) with adenosine. Calculating the instantaneous wave-free ratio (iFR), a measure of resting intracoronary resistance, researchers found it correlated very closely with FFR (r=0.90, P<0.001), Justin Davies, MBBS, MRCP, PhD, from Imperial College London, and …
