title: Mitral valve plasty for a hammock mitral valve in an adult patient.
abstract: A 50-year old woman presented with arterial thrombosis in the right leg. Echocardiography revealed a mobile left atrial thrombus and severe mitral stenosis. She underwent a left atrial thrombectomy, the maze procedure and mitral valve plasty. Anterior and posterior mitral leaflets arose directly from the anterior papillary muscle, and from the posterior papillary muscle intervened by short chordae. This suggested a hammock mitral valve. A posterior papillary muscle division and commissurotomy were performed. The anterior leaflet was divided off the anterior papillary muscle, then extended by a triangular-shaped autologous pericardial patch and apically reattached. The postoperative mean pressure gradient of the mitral valve was 2.2 mmHg, and there was no regurgitation. The patient was in NYHA Class 1 and in sinus rhythm, 14 months after the operation.
