To assess the clinical value of iFR to characterize, without concomitant administration of hyperemic agents and outside a specified range of iFR values, coronary stenosis severity as determined with fractional flow reserve (FFR)
A Prospective, Observational, Non-randomized, Double Blind, Global, Multi-center Registry With an Adaptive Design, Investigating the Diagnostic Utility of Instantaneous Wave-free Ratio™ (iFR®) in Assessing Coronary Stenosis Relevance.
