ObjectiveRepair of the bicuspid aortic valve may be performed in aortic regurgitation and aneurysm. Dilatation of the atrioventricular junction has been identified as a risk factor for repair failure, and we have used suture annuloplasty to correct atrioventricular junction enlargement. The objective was to compare the early results of aortic repair with and without annuloplasty.MethodsBetween November 1995 and January 12, a total of 559 patients were treated with bicuspid aortic valve repair for predominant regurgitation (n = 389), aortic aneurysm (n = 158), or acute dissection (n = 12). Isolated valve repair (aortic valve repair) was performed for aortic valve regurgitation with preserved aortic dimensions (n = 208) and sinotubular junction remodeling plus valve repair for aortic aneurysm and preserved root size (n = 116). Root remodeling was used for dilatation involving the root (n = 235). In 193 patients, dilatation of the atrioventricular junction (>27 mm) was corrected with suture annuloplasty.ResultsHospital mortality was 0.5% (n = 3); 2 patients required pacemaker implantation. Reoperation was necessary for recurrent regurgitation (n = 54) or stenosis (n = 2); 10-year freedom from reoperation was 82% but was inferior after isolated valve repair (70%, P = .007) compared with the 2 other techniques. Application of suture annuloplasty improved 3-year freedom from reoperation after isolated repair (84%) to 92% (P = .07). In all groups, the proportion of patients with no or trivial regurgitation was significantly higher with annuloplasty.ConclusionsPreservation of the bicuspid aortic valve is feasible in many patients. Long-term stability of the repaired valves is good; the negative impact of a dilated atrioventricular junction can be reduced by suture annuloplasty.Copyright © 2013 The American Association for Thoracic Surgery.
