Background The goal of the present study was to investigate the feasibility of mitral valvle repair in patients with infective endocarditis (IE). Methods and Results Twenty-one patients who had undergone mitral valve surgery for IE were reviewed. Valve repair was performed in 8 patients with active and in 6 patients with healed endocarditis : 6 of these 14 patients were New York Heart Association (NYHA) functional class III or IV preoperatively. Valve replacement was performed in 5 patients with active endocarditis and in 2 with healed endocarditis : 6 of these 7 patients were NYHA functional class III or IV preoperatively. Repair techniques included annuloplasty (n=13), resection-suture (n=13), chordal transfer (n=2), and closure of the perforation (n=3). In the valve replacement group, 6 patients required concomitant aortic valve replacement. In the valve repair group, 1 patient died and 1 patient required reoperation for recurrent mitral regurgitation. Postoperative echocardiography demonstrated no (n=8) or mild (n=4) mitral regurgitation at the last follow-up examination. In the valve replacement group, 1 patient died and 1 patient required reoperation because of a paravalvular leak. No cases of recurrent infection occurred in either group. Conclusions Mitral valve repair in patients with IE is feasible and has low morbidity.
