Concurrent Transcatheter Aortic Valve Implantation and Percutaneous Transvenous Mitral Commissurotomy for Totally Percutaneous Treatment of Combined Severe Rheumatic Aortic and Mitral Stenosis.

Transcatheter aortic valve implantation (TAVI) is a new promising therapeutic option for patients with symptomatic severe calcific aortic valve stenosis (AS) who are inoperable or at high risk for conventional cardiac surgery. Percutaneous transvenous mitral commissurotomy (PTMC) is performed routinely in patients with severe mitral stenosis (MS) having a favorable anatomy. Although concurrent TAVI and PTMC is a theoretically possible approach in the treatment of patients with severe AS and MS who are unsuitable for conventional surgery, no cases have yet been reported in which this combined technique is used. For patients with severe AS and MS, the standard therapy is replacement of both the mitral and aortic valves. Herein are presented the details of a 52-year-old woman with urethral carcinoma, in whom simultaneous TAVI and PTMC was the chosen technique to treat combined severe rheumatic AS and MS in a single procedure.
