Anomalous chordae tendinae (CT) originating from mitral valve leaflet is a rare congenital mitral valve anomaly. Our case report is unique as this anomaly is extremely rare in this pediatric age group. The anomalous CT extended from anterior mitral leaflet to the atrial septum (AS). Surgical repair in the form of anomalous CT excision, anterior leaflet chordoplasty, and posterior mitral annuloplasty was successfully performed. Congenital mitral valve (MV) leaflet or chordae anomalies are rare. In anomalous CT from MV leaflet to the AS, the surgical experience is extremely limited and only reported in adults and adolescents. We describe an unusual presentation of severe mitral insufficiency (MR) associated with anomalous CT from the anterior mitral valve leaflet (AMVL) to the AS that prompted successful repair during childhood.
源自二尖瓣叶的异常腱索（CT）是一种罕见的先天性二尖瓣异常。我们的病例报告很独特，因为这种异常在这个儿科年龄组中极为罕见。异常腱索从二尖瓣前叶延伸至房间隔（AS）。以异常腱索切除、前叶腱索成形术和二尖瓣后瓣环成形术的形式进行的手术修复成功完成。先天性二尖瓣（MV）叶或腱索异常很少见。在从MV叶到AS的异常腱索病例中，手术经验极其有限，仅在成人和青少年中有报道。我们描述了一种与从二尖瓣前叶（AMVL）到AS的异常腱索相关的严重二尖瓣反流（MR）的不寻常表现，这促使在儿童期成功进行了修复。
