The ADVISE Hyperemic Stenosis Resistance (HSR) Study assessed 51 lesions, calculating Volcano iFR® Functionality, FFR, and a third independent metric of lesion severity, HSR. iFR® Functionality showed the same diagnostic accuracy versus HSR (92%) as FFR versus HSR (92%). iFR® Functionality showed an Area Under the Curve (AUC) of 0.93 versus HSR, which had no statistical difference from the AUC of FFR versus HSR of 0.96 (p=0.48). The study also showed that in the 4 of 51 lesions (8%) that disagreed between Volcano iFR® Functionality and FFR, there was equal agreement with HSR. The data confirms that Volcano iFR® has comparable accuracy as FFR when both are compared to an independently validated metric of lesion severity (HSR).
