Long-term Outcomes After Bicuspid Aortic Valve Repair With an External Aortic Ring Annuloplasty
Abstract
Results: 152 patients with bicuspid aortic valve underwent surgery of whom 83 patients had valve sparing remodelling with external ring annuloplasty, 24 patients had valve repair with external ring annuloplasty and ascending aortic replacement, 31 patients had isolated aortic valve repair with single external ring annuloplasty at the annulus level and 14 patients had isolated aortic valve repair with double ring annuloplasty at the annulus and STJ levels. Mean age was 46.5±12.8 years, and 92 (60.5%) patients had > 2 AI. Overall 30-day mortality was 0.7%, 1 patient (0.7%) had postoperative stroke and 3 (2%) required PPM post-surgery with no differences between the groups. Long-term follow up demonstrated 91% overall survival, 88% freedom from aortic related re-intervention and 86% freedom from AI>2 at 8 years. Sub-analysis demonstrated that the recurrence of significant AI> 2 and aortic related re-intervention were driven by the isolated aortic ring repair with single annuloplasty (63% vs 100%, p<0.001 and 70% vs 99%, p<0.001 respectively).
