Description
Summary:[...]the excellent exposure of the aortic valve and uniformity of treatment strategies for aortic valve disease lead to focused learning and increased repetition during surgical training. Clinical trials comparing new versus established procedures might be overestimating the treatment effect of the latter, as surgeons are more familiar with them. [...]low- and high-volume surgeons are typically included in the same trial, and few studies provide information on surgeon effect due to variation in expertise. [...]for MVR, both cumulative 5-year volume and annual volume are related to operative outcome.
