Background and Aim of the StudyCongenital mitral valve (MV) dysplasia is a relatively rare and highly complex cardiac disease. We present our results and illustrate the techniques used to repair these valves. MethodsBetween 1972 and 2014, 100 consecutive patients underwent surgical repair of congenital MV dysplasia at our institution. Predominant MV regurgitation was present in 53 patients (53%) whereas mitral stenosis was prevalent in 47 (47%). ResultsThere were five early (5%) and eight late deaths (9%). Actuarial survival was 95%, 94%, and 93% at 5, 10, and 20 years, respectively. Sixteen patients (18%) required reintervention due to subsequent MV dysfunction. Actuarial freedom from reintervention for MV dysfunction was 95%, 92%, and 89% at 5, 10, and 20 years, respectively. ConclusionsThe mechanism underlying the valve dysfunction in congenital mitral valve dysplasia is multifactorial and requires the application of a variety of surgical techniques for repair
