A 77-year-old Japanese woman was diagnosed with mitral valve infective endocarditis caused by Staphylococcus aureus. She developed heart failure due to the perforation of posterior mitral leaflet. Mitral valve replacement with a 27-mm Carpentier-Edwards (Edward Lifesciences, Irvine, California) bioprosthesis was performed. She needed percutaneous cardiopulmonary support for 3 days after this operation. Ten days after the operation, a 3-dimensional (3D) transesophageal echocardiography (TEE) clearly showed that 2 of 3 leaflets did not fully open and 2 leaflets fused (A and B, arrows; Online Video 1). We performed percutaneous transvenous mitral commissurotomy (PTMC) for this unusual case. The PTMC was performed with a 22-mm Inoue balloon catheter (Toray, Tokyo, Japan) under the TEE guidance. Post-operative 3D TEE showed a separation of 2 fused leaflets that resulted in a smooth movement of these leaflets (C and D, Online Video 2). Transmitral Doppler tracing shows marked improvement of mitral stenosis of the bioprosthetic valve (E and F).
