Reconstruction of the free margin of the anterior mitral leaflet with autologous pericardium in active infected endocarditis.

In patients with active infective endocarditis mitral valve repair is better than mitral valve replacement, but it remains a challenge when there has been massive destruction of the rough zone of the anterior leaflet. We report a technical modification of mitral valve repair for advanced active infective endocarditis in which a widely infected rough zone and the chordae were successfully replaced with autologous pericardium and multiple artificial chordae. The procedure described here is capable of improving the prospects of mitral valve repair in advanced infective endocarditis.
