Several studies tested the utility of fractional flow reserve (FFR) to assess coronary lesions functionally. The FFR required for its measurement amaximum hyperemia that usually, is achieved with adenosine infusion. The “InstantaneousWave-freeRatio™” or iFR, has the advantage of not requiring maximum hyperemia.This prospective, multicenter, observational study that included 690 patients detectedthat iFR adequately classified 91.6% of the population compared to the conventional FFR.The authors concluded that both methods are comparable to the functional assessment of coronary lesions.
