Background Microvascular resistance reserve (MRR) is a recently introduced specific index of coronary microcirculation. MRR calculation can utilize parameters deriving from flow (CFR) assessment, provided that intracoronary pressure data are also available. The previously proposed pressure-bounded CFR (CFRpb) defines the possible interval on basis resting and hyperemic gradients in epicardial vessel, however, its correlation to Doppler wire measurement was reported be rather poor without...
In order to make optimal decisions on the treatment of atherosclerotic coronary heart disease (CHD), appropriate evaluation is necessary, including both anatomical and physiological assessment arteries. According current guidelines, a fractional flow reserve (FFR)–based clinical decision recommended, but (CFR) measurements microvascular should also be considered in special cases for detailed exploration state. We aimed generate an extended during routine FFR measurement define new...
Abstract Background The pressure-bounded coronary flow reserve (CFRpb) defines the possible CFR interval (between CFRpbmin and CFRpbmax) using intracoronary pressure data. However, its correlation to Doppler wire measurement was reported be poor, partly due non-inclusion of hydrostatic error in calculations. Microvascular resistance (MRR), a specific index microcirculation, can calculated from data (Pa: aortic pressure, Pd: distal pressure) by following equation: MRR= CFR; × (Pa, rest)/(pd,...
