Comparison of Resting Full-Cycle Ratio and Fractional Flow Reserve in a German Real-World Cohort [PDF]
Frontiers in Cardiovascular Medicine, 2021 Objective: The aim of this study was to evaluate non-hyperemic resting pressure ratios (NHPRs), especially the novel “resting full-cycle ratio” (RFR; lowest pressure distal to the stenosis/aortic pressure during the entire cardiac cycle), compared to the

Long‐Term Clinical Outcomes of Nonhyperemic Pressure Ratios: Resting Full‐Cycle Ratio, Diastolic Pressure Ratio, and Instantaneous Wave‐Free Ratio [PDF]
Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020 Background Nonhyperemic pressure ratios (NHPRs) such as instantaneous wave‐free ratio, resting full‐cycle ratio, or diastolic pressure ratio have emerged as invasive physiologic indices precluding the need for hyperemic agents.

Invasive physiologic assessment of coronary artery stenosis by resting full-cycle ratio and fractional flow reserve: a prospective observational study [PDF]
Scientific Reports, 2023 Resting full-cycle ratio (RFR), an alternative to fractional flow reserve (FFR) for evaluating intermediate coronary artery stenosis, helps reduce patients’ time, cost, and discomfort. However, the validation data for RFR and FFR are lacking. We aimed to

Utility of Saline-Induced Resting Full-Cycle Ratio Compared with Resting Full-Cycle Ratio and Fractional Flow Reserve [PDF]
Journal of Interventional Cardiology, 2020 Background. The saline-induced distal coronary pressure/aortic pressure ratio predicted fractional flow reserve (FFR). The resting full-cycle ratio (RFR) represents the maximal relative pressure difference in a cardiac cycle. Therefore, the present study
