AVR
26,742 males (58.3%) and 19,168 females (41.7%) underwent an elective or urgent isolated AVR (see table 3). Females tended to be older but were more likely to have an elective rather than urgent AVR compared to males (see supplementary table 1).
Females had shorter cross clamp times and CPB times than males. Biological aortic valves were most commonly implanted in both males and females but males were more likely to receive a mechanical implant or autologous graft than females.
