Transcatheter Mitral Valve-in-Valve Dislocation: A Rescue Strategy

In the transcatheter aortic valve replacement era, transapical valve-in-valve mitral valve implantation is considered an alternative treatment for high-risk patients with degenerated mitral bioprosthesis. We report an unusual strategy to remedy the potentially fatal complication of the mitral prosthesis migration into the aortic arch. The dislocated prosthesis was successfully stabilized in the aortic arch with a bare aortic stent, ensuring adequate perfusion of epiaortic vessels. © 2018 The Society of Thoracic Surgeons
