Abstract

BACKGROUND: At our institution, type I bicuspid aortic valve (BAV) patients with aortic insufficiency (AI) who are candidates for valve preservation are stratified into two groups by aortic root pathology: nonaneurysmal root undergoing primary cusp repair+subcommissural annuloplasty (repair group) vs aneurysmal root undergoing primary cusp repair+root reimplantation (reimplantation group). We report outcomes of this surgical reconstructive strategy for the repaired type I BAV.

METHODS: A retrospective review was performed of 71 patients with a type I BAV undergoing primary valve repair from 2005 to 2012. The repair group (n=40) underwent annular stabilization by subcommissural annuloplasty, and the reimplantation group (n=31) underwent robust annular stabilization provided by root reimplantation.

RESULTS: Preoperative characteristics and root anatomy were similar, except for increased root dimensions in the reimplantation group (p

CONCLUSIONS: Root stabilization with the reimplantation technique significantly improves the durability of the repaired type I BAV compared with subcommissural annuloplasty. It also provides improved and sustained valve mobility (transvalvular gradients).
