Simultaneous transapical aortic and mitral valve-in-valve implantation for double prostheses dysfunction: Case report and technical insights

Transcatheter "Valve-in-Valve" implantation (ViV) has shown promising results in high-risk patients suffering from structural valve deterioration (SVD) of a previously implanted heart valve bioprosthesis. We present a case of a 68-year-old woman with a history of three previous cardiac operations on the aortic and mitral valve. At the time of admission she was severely symptomatic due to a simultaneous SVD of a 23 mm aortic and of a 29 mm mitral St. Jude Biocor bioprosthesis. Because of the history of several cardiac operations and to her comorbidities, the patient was considered with an extremely high surgical risk profile and was therefore scheduled for double concomitant mitral and aortic ViV. Through a trans-apical approach, the patient underwent 23 and 29 mm Edwards Sapien XT implantation in the aortic and mitral bioprosthesis, respectively. The procedure was uneventful as well as the following hospital stay. At 6-months follow-up the patient is in NYHA class I. Echocardiography shows that the aortic bioprosthesis has no leak and the mean gradient is 20 mm Hg while the mitral valve has mild leak and maximum and mean gradients are 21 and 10 mm Hg, respectively. The three main technical aspects that should be carefully considered in double concomitant ViV are: sequence of valve deployment (whether to implant the mitral or the aortic valve first), choice of access and valve sizing. In conclusion, double simultaneous trans-apical mitral and aortic ViV is technically feasible. © 2014 Wiley Periodicals, Inc. © 2014 Wiley Periodicals, Inc.
