Abstract:
We describe a case of hammock mitral valve in an adult. A 38-year-old woman presented with recently acquired dyspnea. Echocardiography showed severe mitral stenosis related to a hammock mitral valve characterized by the presence of an overdeveloped papillary muscle that gives short chordae to both mitral leaflets. No other valve insufficiency was noted. At operation, we observed direct continuity accompanying several fenestrations between both leaflets and the huge abnormal muscular band just underneath the mural leaflet. Resection of the anterior leaflet and was successfully replaced with a bioprosthetic valve. Her postoperative course was unremarkable.
