Background. The advantages of mitral valve repair in myxomatous regurgitation are well established. The durability of this reconstructive procedure is variable. The timing of operation is the surgeon dilemma. The aim of this study was to evaluate the early and long-term results of mitral valve repair in myxomatous regurgitation. Methods. Between January 1990 and December 1997, 121 patients (77 males, 44 females) were operated on for myxomatous regurgitation with mitral valve repair. The surgical indication was based on the severity of mitral valve insufficiency and left ventricular dysfunction rather than the functional class. The surgical techniques were: quadrangular resection of the posterior mitral leaflet and sliding suture, triangular resection of the anterior mitral leaflet, chordal transposition and neo-chords suture, prosthetic ring (Carpentier-Edwards and Biflex rings) suture. Results. There was 1 hospital death (0.8%). Long-term follow-up between 6 months and 107 months was available in 100% surviving patients. There were 6 late deaths, 3 for cardiac and 3 for non-cardiac events. Conclusions. Valve repair in mitral regurgitation caused by myxomatous disease provides excellent survival results at 51 months. Adverse outcome occurs in patients with preoperative left ventricular dysfunction, even if asymptomatic.
