Relationship between coronary diastolic pressure indexes during the wave ‐free period and a novel pressure‐derived index: Diastolic pressure ratio at the optimal point

ConclusionsA simple pressure ‐derived physiological marker of coronary stenosis, DROP, might represent other diastolic pressure indexes with a numerical equivalency to the instantaneous wave‐free ratio. DROP can be measured automatically assuming that the rising points on the aortic pressure curve are detectable. However, f urther large‐scale clinical investigations are needed to determine whether DROP could contribute to the further generalization of physiology‐guided percutaneous coronary intervention.
