Mitral valve repair for degenerative mitral regurgitation.

Mitral valve repair for degenerative mitral regurgitation is nowadays one of the most common valvular procedures. Different technical modifications were added to the original Carpentier's method, trying to maximise the stability of the results and to reduce the incidence of immediate complications and of late failure of the correction. Survival is good, even if recent reports showed that recurrence of mitral regurgitation can be higher than expected. Prolapse of the anterior leaflet remains challenging and is related to higher reintervention rates. Nevertheless, the overall success rate is high, and the increasing experience of the different surgical teams approaching this procedure will help maintain satisfactory and stable long-term results.
