Novel Microvascular Resistance Reserve Index May Be Useful Prognostic Marker in Heart Transplant Patients Impaired microcirculatory function determined by microvascular resistance reserve MRR index early after heart transplantation is associated with increased risk for death or acute cellular rejection regardless of epicardial coronary artery stenosis or elevated microcirculatory resistance new patient data suggests. IVUSGuided PCI Optimization in Low PostPCI FFR Failed to Significantly Reduce TVF at 3Year FFR REACT Trial FollowUp Intravascular ultrasound IVUSguided percutaneous coronary intervention PCI optimization of low postprocedure fractional flow reserve FFR values was associated with a clinically relevant but statistically nonsignificant 42 reduction in target vessel failure TVF compared with standard of care at 3year followup in the FFR REACT trial. SWEDEHEART Data Shows IFR and FFR Have Comparable MACE in RealWorld Clinical Settings Coronary revascularization guided by instantaneous wavefree ratio IFR or fractional flow reserve FFR had similar outcomes with no discernible differences in major adverse cardiovascular events MACE or any of its individual components or differences in mortality related to cardiovascular cardiac or coronary artery disease according to new data from the SWEDEHEART National Registry. Measuring Guidewire Friction for Retrieving HighPressure in PCI Researchers find that a couple guidewires BMW Abbott and Grand Slam Asahi Intecc require less force to retrieve the OPNNC balloon during superhighpressure balloon percutaneous coronary intervention PCI.
