Reconstruction of anterior mitral leaflet using autologous pericardial patch combined with posterior leaflet sliding for active infective endocarditis.

We report a case of active infective endocarditis in a young adult, affecting the anterior and posterior leaflets extensively. The patient underwent a mitral valve repair with extended sliding repair on the posterior leaflet and reconstruction using an autologous pericardial patch supported by an artificial chord on the anterior leaflet. Although we finally needed commissure closing for successful repair, we aggressively achieved a repair-oriented strategy using several techniques in a young patient who may have required mitral valve replacement.
