Webmethods are referred to as RFR (Resting Full-Cycle Ratio) and resting FFR (Pd/Pa without hyperemia). Consistent with traditional FFR, RFR and resting FFR require the use of a … Webnew resting indexes have been introduced. The resting full-cycle ratio (RFR) is based on unbiased identification of the lowest distal arterial pressure (Pd)/arterial pres-sure (Pa) within the entire cardiac cycle,9 and the dias-tolic pressure ratio (dPR) is an averaged Pd/Pa ratio dur - ing the entire or other parts of diastolic period without

WebNov 25, 2024 · The resting full-cycle ratio (RFR) is a unique non-hyperemic index which is calculated as the point of absolutely lowest distal pressure to aortic pressure during entire cardiac cycle. It is unclear whether RFR may detect functionally significant coronary stenosis that cannot be detected with other resting indices due to differences in the cardiac cycle. WebNov 30, 2024 · The resting full-cycle ratio (RFR) is based on unbiased identification of the lowest distal arterial pressure (Pd)/arterial pressure (Pa) within the entire cardiac cycle, 9 … WebApr 7, 2024 · The resting index diastolic pressure ratio (dPR) is an excellent alternative to the instantaneous wave-free ratio (iFR). Despite angiographically successful percutaneous coronary intervention (PCI), in a significant number of vessels the post-PCI dPR remains suboptimal (≤ 0.89). Post-PCI dPR is associated with clinical outcome at follow-up. glass fibre wire
