Valve repair in infective endocarditis

From 1985 to 1995, 12 patients with native valve endocarditis underwent valve repair instead of replacement. Mean age was 41.9 years (range from 5 to 79 years). Eight patients had active and 4 patients inactive infection. The mitral valve was involved in 6 patients, the aortic valve in 1, both valves in 2, the tricuspid valve in 2, and the mitral and pulmonary valves in 1. The pathological findings were as follows: leaflet perforation in 2 patients, chordal rupture in 3, and vegetations in 10. Valve sparing procedures were carried out on the mitral valve in 8 patients, on the aortic valve in 1, on the tricuspid valve in 2, and on the pulmonary valve in 1. The following repair techniques were used: vegetectomy in 10 patients, leaflet patching in 2, posterior mitral leaflet resection in 3, mitral annuloplasty in 4, and pulmonary valve repair in 1. Uncontrolled sepsis, progressive heart failure, peripheral embolism, and echocardiographically demonstrated vegetations were the indications for surgery. There was no operative or late mortality and all infections were cured with no recurrences. One patient required valve replacement following aortic valve repair because of progressive aortic regurgitation. Postoperative Doppler echocardiography showed trivial to no regurgitation in 11 patients after valve repair. The overall outcome was favorable during the mean follow-up period of 39.3 months (range from 1 to 120 months). Reparative or reconstructive approaches for native valve endocarditis should be considered and can be successfully performed. Their advantages include (1) improved hemodynamics, (2) no recurrence, (3) no mortality and (4) favorable long-term results.
