Key PointsQuestionWhat is the long-term stability of bicuspid aortic valve repair for aortic regurgitation and/or aneurysm, and what are the risk factors associated with valve failure? FindingsIn this case series of 1024 patients who underwent bicuspid aortic valve repair with a differentiated anatomic repair approach, 15-year survival was 82%. Cusp calcification, asymmetric commissural orientation, and the need for partial cusp replacement were risk factors associated with valve failure. MeaningBicuspid aortic valve repair with or without concomitant aortic replacement is associated with long-term stability if all pathologic components of the aortic valve and root, including commissural orientation, are addressed.
