Mitral Valve Repair for Anterior Leaflet Prolapse With Expanded Polytetrafluoroethylene Sutures

Twelve-year echocardiographic follow-up demonstrates good long-term results of chordal replacement with expanded polytetrafluoroethylene sutures for anterior mitral leaflet prolapse. To avoid recurrence of regurgitation, a significantly high level of competence of the valve is essential in the repair of anterior mitral leaflet prolapse.
