Mitro-Aortic Valve-in-Valve Procedures: Many Challenges in Little Space

Redo multiple valve replacement is known to carry additional risk of morbidity and mortality. Currently, a transcatheter-based valve-in-valve approach could be useful in reducing potential serious consequences. On the other hand, this approach poses several technical challenges regarding the device and procedural aspects of the procedure. We present the case of a 78-year-old man who presented with symptoms of heart failure due to mitro-aortic bioprosthesis degenerations who was deemed to be at extremely high risk for conventional redo surgery. A two-steps single admission transcatheter-based approach was planned with a transfemoral aortic valve-in-valve procedure followed by a trans-apical mitral valve-in-valve implantation. The outcome was good and the recovery was fast.
