Introduction: Bicuspid aortic valve is the most common congenital heart disease. Traditionally, aortic valve replacement hasbeen the approach for patients requiring surgery. After introduction of the bicuspid aortic valve repair concept, our groupbegan reproducing these techniques, which have been standardized and homogeneously applied at our institutions.Objectives: The aim of this study was to review the conjoint experience of three centers and show the mid- and long-termresults of bicuspid aortic valve repair.Methods: Between October 1995 and February 2013, 666 patients with bicuspid aortic valve underwent surgery for aorticregurgitation and/or aortic aneurysm. Isolated aortic regurgitation was present in 254 patients, and 412 had aortic aneurysmor dissection. The valve was reconstructed in all the patients (isolated valve repair in 254, “remodelling of the aortic root” in281, remodelling of the sinotubular junction in 129 and “reimplantation” technique in 2).Results: Mortality was 3/666 (0.5%): 1/254 (0.4%) after isolated valve repair and 2/410 (0.5%) after valve repair plus aortic replacement.In patients with combined procedures (coronary revascularization or mitral/tricuspid valve repair), mortality was 1/77 (1.3%).During follow-up, 12 patients died (10-year survival: 95%). Freedom from reoperation and from aortic valve replacement at10 and 15 years were 80% and 77%, and 86% and 83%, respectively. Freedom from reoperation at 10 years was higher withaortic root (86%) or tubular aorta (84%) replacement, compared with isolated valve repair (74%; p = 0.005). Freedom fromany valve-related complication was 80% and 77% at 10 and 15 years, respectively, and was better for valve repair including“remodelling of the aortic root” (87% and 82%) than for isolated repair (77% and 77%; p = 0.04).Conclusions: Bicuspid aortic valve repair is a safe, long-lasting procedure, with a low incidence of mid- and long-term “valverelatedcomplications”.
