Between January 1999 and August
2002, 13patients with mitral regurgitation resulting from native
valve endocarditis underwent surgery. The age of these patients
was 54±13.8years (range, 27 to 74years); 8 patients were men.
Five patients were categorized as New York Heart Association
functional class III or IV. Endocarditis was active in 3 patients.
Emergency or urgent surgery was required in 4 patients. Twelve
patients underwent repair, and one had a valve replacement. Following
the removal of all infected or nonviable tissue, a decision was
made as to the possibility of repair. Repair was attemped in
13 patients and was successful in 12 patients. Most patients
received ring annuloplasty with a Carpentier-Edward ring. Six
patients had chordae ruptures, 5 patients had vegetations, and
2 patients had elongated chordae. Twelve patients were categorized
as New York Heart Association functional class I, and one was
categorized as class II at discharge. There were no hospital
deaths. The mean follow-up of the 13 survivors was 24±14 months
(range from 3 to 43 months). There were no late deaths, reoperations,
recurrent endocarditis, thromboembolic events, or other valve-related
morbidities. We conclude that mitral valve repair is an effective
treatment for infective endocarditis with mitral regurgitation.
