Fate of the Aortic Root Late After Ross Operation

Abstract

Autograft dilatation is common late after the Ross procedure, particularly in younger patients, in those with preoperative aortic aneurysm, and those having root replacement without support of anulus and sinotubular junction. Bicuspid aortic valve is not a risk factor. Significant autograft valve dysfunction affects a minority of patients, but it is more prevalent in those with autograft dilatation.
