Mitral valve replacement after transcatheter aortic valve implantation in a patient with rheumatic heart disease and prior Ross procedure: a case report

Abstract Background Reoperations are required frequently after the Ross procedure in rheumatic patients. The use of transcatheter aortic valve implantation (TAVI) in those patients could decrease the risk of future open procedure; however, the outcome may be affected by the concomitant mitral valve disease, and subsequent mitral reoperation may distort the implanted aortic valve. Case presentation We present a female patient who had a beating mitral valve replacement after valve-in-valve TAVI in a patient with prior Ross procedure. Weaning from cardiopulmonary bypass was difficult, and the patient needed extra-cardiac membrane oxygenation (ECMO) and intra-aortic balloon pump because of right ventricular dysfunction. The right ventricular dysfunction could be due to the concomitant coronary artery disease or air embolism during the beating mitral valve surgery. Recovery was gradual, and the patient was discharged after 33 days. Pre-discharge echocardiography showed a maximum gradient of 9 mmHg on the aortic valve and mild paravalvular leak. Conclusions Mitral valve replacement in a patient with prior TAVI and the Ross procedure was feasible; it decreased the operative risk and did not distort the implanted aortic valve.
