AMERICAN ASSOCIATION FOR THORACIC SURGERYfunctional aortic annuloplasty using sub-commissural annuloplasty (n = 52),ascending aortic replacement (n = 17) or aortic root replacement (n = 54) using areimplantation (76%) or remodelling technique (24%). Clinical (median: 57months, range [1–147]) and echocardiographic (median: 40 months, range [1–143])follow-up was complete in 99% of patients. Kaplan-Meier and Cox regression analyseswere used.RESULTS: There was no operative mortality. Five patients underwent early aorticvalve reoperation (3 re-repairs, 2 Ross procedure). Post-repair, intraoperativeechocardiography revealed AI grade 0/1 in all patients. On discharge echocardiography,92% of patients had AI grade 0/1 and 8% had grade 2 AI. Three additionalpatients underwent aortic valve replacement during follow-up. Overall survivalwas 97 ± 3% at 8 years. At 5 and 8 years follow-up, freedom from AV reoperationwas 95 ± 4% and 92 ± 7% and freedom from AV replacement was 97 ± 3% and 94± 6%. Freedom from recurrent AI (>2+) was 94 ± 5% and from valve related eventswas 88 ± 4% at 5 years.CONCLUSION: A systematic approach to bicuspid aortic valve repair yields goodearly and mid-term results. Repair of bicuspid valves for AI is a feasible and attractivealternative to mechanical valve replacement in young patients.TUESDAYMorning155
