Partial mitral valve replacement for acute endocarditis.

We present a case of acute endocarditis involving the posteromedial commissure and both leaflets of the mitral valve, including a vegetation on and perforation of the anterior leaflet, in a young man with active Crohn's disease. Repair was performed using glutaraldehyde-treated bovine pericardium. Competence of the valve was achieved with no recurrence of endocarditis. This case demonstrates that extensive destruction of both leaflets of the mitral valve does not prohibit repair.
