Long-Term Outcomes of Chordal Replacement With Expanded Polytetrafluoroethylene Sutures to Repair Mitral Leaflet Prolapse

The authors demonstrated that re-do cardiac surgery and isolated anterior leaflet prolapse resulted in an increased hazard of mitral valve reoperation. The probability of recurrent moderate or severe mitral regurgitation using repeated measures regression models was 14.1% at 20 years. Variables associated with recurrent MR in multivariable regression analysis were left ventricular ejection <40% and preoperative complete heart block. 
David et al. note that chordal replacement with expanded polytetrafluoroethylene sutures provides stable mitral valve function in most patients during the 20 years of follow-up.
