Tmn, mean transit time; Q, absolute volumetric flow; Rμ, absolute microvascular resistance; WU, wood units.
A total of 27 paired coronary physiological measurements for the LAD and RCA of patients with severe aortic valve stenosis. Data are shown as median and interquartile range or mean ± SD. CFR adjusted for FFR is calculated as CFR divided by FFR.
