[Residual Mitral Regurgitation after Repair for Posterior Leaflet Prolapse;Importance of Preoperative Anterior Leaflet Tethering].

Carpentier's techniques for degenerative posterior mitral leaflet (PML) prolapse have been established with excellent long-term results reported. However, residual mitral regurgitation( MR) occasionally occurs even after a straightforward repair, though the involved mechanisms are not fully understood. We sought to identify specific preoperative echocardiographic findings associated with residual MR after a PML repair.We retrospectively studied...
