Congenital absence of anterior papillary muscle of the tricuspid valve and surgical repair with artificial chordae.
We report the case of a 26-year old woman who underwent successful tricuspid valve repair for the absence of the anterior papillary of the tricuspid valve. Preoperative echocardiography revealed grade IV tricuspid valve regurgitation, caused by congenital absence of the anterior papillary muscle and prolapse of the anterior leaflet. Tricuspid valve repair was performed using artificial chords consisting of two polytetrafluoroethylene sutures and a concomitant ring annuloplasty. Postoperative echocardiography revealed mild tricuspid valve regurgitation. This approach represented a safe and effective technique for tricuspid valve repair in congenital absence of papillary muscle.
