Mitral valve repair using polytetrafluoroethylene neochordae: short-term outcomes

In recent years, mitral valve repair using polytetrafluoroethylene (PTFE) neochordae has been shown to be an effective technique for correcting valve prolapse due to chordal rupture or elongation. In this study, we evaluated our experience using this technique in a group of 21 patients. The median (range) follow-up period was 9 (1-26) months. There was no in-hospital mortality. During follow-up, improvement in both clinical and echocardiographic parameters were observed: 95.2% of patients were in I-II NYHA class and the mitral regurgitation jet area was less than 4 cm(2) in 85.7% of patients. These findings are consistent with those previously reported in the literature. However, these results relate to our initial experience, and long-term follow-up is still required.
