Impact of Preoperative Anterior Leaflet Tethering on the Recurrence of Ischemic Mitral Regurgitation and the Lack of Left Ventricular Reverse Remodeling after Restrictive Annuloplasty

Anterior mitral leaflet tethering is a powerful predictor of MR recurrence and lack of LVRR after undersized mitral ring annuloplasty. Evaluation of leaflet tethering should be incorporated into clinical risk assessment and prediction models.
