How Does Mitral Valve Repair Fail in Patients With Prolapse?—Insights From Longitudinal Echocardiographic Follow-Up

This single institution study explored the frequency and time course of failure of mitral valve repair for MR caused by prolapse using longitudinal echocardiography.   Recurrent MR developed in 49 (5.7%) patients at a mean of 3.1 years; 6 had prolapse and 43 did not.   Severe MS occurred in 3.  Reoperation was performed in 21 patients, and was most commonly valve replacement.
