Mid-term results of mitral valve repair for complicated active bacterial endocarditis in high-risk patients.
Mitral valve repair in endocarditis achieves a competent valve and prevents septic embolization and acute left ventricular failure, in which operative mortality could be increased. Early and mid-term results were examined to establish whether emergency mitral valve repair offers an advantage in complicated active endocarditis. Ten patients with complicated active native valve endocarditis underwent mitral valve repair. The mean age was 45.8 +/- 18.5 years; two patients were female (20%). All patients had severe mitral regurgitation, which combined in one patient with mitral valve stenosis. New York Heart Association (NYHA) functional class was IV in all patients. The macroscopically infected tissue with vegetation in all patients was excised. Multiple techniques were required to achieve valve competence. There was one (10%) hospital death in a patient with persistent congestive heart failure, and a reoperation in another (10%) after 2 years. Mean follow-up was 32.1 +/- 12.7 months (range 1-45 months) and was complete. There were no late deaths, recurrent endocarditis, or thromboembolic events. Seven patients (77.7%) were in NYHA functional class I, and two (22.2%) were in class II. Mitral valve repair in complicated active bacterial endocarditis limited to leaflet tissues has a low operative mortality and valve-related morbidity, with promising mid-term survival in high-risk patients.
