Objective: To evaluate timing for surgery and management of complex valve lesions in patients with active mitral valve (MV) endocarditis. Results are based on 13 years of experience with MV repair in active endocarditis. Method: Between 1993 and 2005, 81 patients were operated for active MV endocarditis, of which 63 (or 78%) had MV repair. For all patients, the median time between diagnosis and surgery was 10 days. Diverse surgical techniques were applied to restore MV competence. In 59% of the patients, pericardial patches, tricuspid autograft or partial MV homografts were used as leaflet substitutes. In addition, prosthetic rings were employed in 44% of the patients. Results: The overall operative mortality was 17.5%. However, considering only patients in preoperative NYHA class I or II, the operative mortality could be reduced to 4.8%. NYHA class 3, elevated age (above 70 years) and history of valvular were the three independent risks factors for early mortality in our multivariate analysis. The average follow-up time was 60 ± 37 months. During this period, five late deaths occurred, two of which were cardiac-related. The overall 5- and 10-year survival rate was 73 ± 12% and 69 ± 13%, respectively. In hospital survivors, freedom from cardiac death after 5 and 10 years was 93 ± 8%. Three early and five late MV reoperations occurred in seven patients, of them four could have MV re-repair. Only one endocarditis recurrence occurred after 4 months in a chronic haeamodialysed patient. Freedom from MV reoperation was 89 ± 10% and 72 ± 24% at 5 and 10 years, respectively. Ten-year freedom from MV replacement and from endocarditis recurrence were 95 ± 5% and 98 ± 1%, respectively. Annular abscesses and calcified or rheumatic MV disease were two independent risk factors associated with reoperation in our multivariate analysis. During the follow-up period, all patients were in NYHA class I or II; 89% of patients had mitral regurgitation grade I, only 11% had grade II on transthoracic echocardiography. Conclusion: Using diverse and advanced techniques of MV repair, a reparability rate of 80% can be reached among patients with active endocarditis. We demonstrate that a high level of safety and excellent durability of MV repair can be obtained even for complex repairs.
