Congenital anomalous chordae tendinae of the mitral valve: an unusual presentation of mitral insufficiency in children.
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.
