Valve preservation or repair of the regurgitant bicuspid aortic valve (BAV) minimizes valve-related complications. The purpose of the current analysis was to determine the proportion of BAVs than can be repaired. Between 2000 and 9/2018, 1168 operations for BAV without stenotic pathology were performed. Of these, 103 underwent isolated aortic valve replacement, the remaining 1055 individuals underwent valve repair. Reasons for replacement were analyzed. The proportion of repaired BAVs remained constant at 85% over the years. The most frequent reasons for replacement were cusp calcification or active endocarditis. In only 2 instances, replacement was performed as intraoperative conversion after failed repair. The vast majority of BAVs can be repaired with good durability as long as cusp substance is preserved.
保留或修复反流性二叶式主动脉瓣（BAV）可最大程度减少瓣膜相关并发症。目前分析的目的是确定可修复的 BAV 比例。2000 年至 2018 年 9 月，1168 例无狭窄性病变的 BAV 接受了手术治疗。其中 103 例行单纯主动脉瓣置换术，其余 1055 例行瓣膜修复术。分析了置换的原因。多年来，修复的 BAV 比例一直保持在 85%不变。置换的最常见原因是瓣叶钙化或活动性心内膜炎。只有 2 例术中因修复失败而转为置换。只要瓣叶结构完好，绝大多数 BAV 都可以通过修复获得良好的耐久性。
