Fate of the moderately diseased aorta; a single center experience.

Abstract

Background The fate of the aorta after tube graft replacement remains unclear as is the future of aortic dilatation in patients receiving other cardiac operations. We investigated the evolution of aortic dilatation after non aortic cardiac operations and the dimensions of the root and arch after ascending aorta replacement. Methods From 252 patients with aortic dilatation operated from January 2010 to June 2019, 160 were followed with computed tomography angiography. Two groups were formed according to the initial operation received. Group I (n=36) included patients with a dilated aorta, unreplaced during different indication cardiac surgery. Group II (n=124) included patients receiving tube graft aorta replacement with or without aortic valve replacement. Mean preoperative and follow-up diameters of the different aortic segments were compared in both groups
