Background-Reconstruction of the regurgitant bicuspid aortic valve has been performed for Ͼ10 years, but there is limited information on long-term results. We analyzed our results to determine the predictors of suboptimal outcome. November 1995 and December 2008, 316 patients (age, 49Ϯ14 years; male, 268) underwent reconstruction of a regurgitant bicuspid aortic valve. Intraoperative assessment included extent of fusion, root dimensions, circumferential orientation of the 2 normal commissures (Ͼ160°, Յ160°), and effective height after repair. Cusp pathology was treated by central plication (nϭ277), triangular resection (nϭ138), or pericardial patch (nϭ94). Root dilatation was treated by subcommissural plication (nϭ100), root remodeling (nϭ122), or valve reimplantation (nϭ2). All patients were followed up echocardiographically (cumulative follow-up, 1253 years; mean, 4Ϯ3.1 years). Clinical and morphological parameters were analyzed for correlation with 10-year freedom from reoperation with the Cox proportional hazards model. Hospital mortality was 0.63%; survival was 92% at 10 years. Freedom from reoperation at 5 and 10 years was 88% and 81%; freedom from valve replacement, 95% and 84%. Methods and Results-Between
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
