title: Transfemoral transcatheter aortic valve implantation in the presence of a mechanical mitral valve prosthesis using a dedicated TAVI guidewire: utility of a patient-specific three-dimensional heart model.
abstract: An 82-year-old woman with severe aortic stenosis was referred. She had previously undergone mitral valve replacement. We planned transcatheter aortic valve implantation (TAVI) with transfemoral approach. We planned to use the Safari-dedicated TAVI guidewire. No studies have reported clinical application of the dedicated TAVI guidewire in a patient with the previous mitral valve replacement. Thus, we conducted a simulation using a three-dimensional heart model to confirm the safety of the procedure. The procedure was successful without any complications. This case is the first to show that the dedicated TAVI guidewire can be safely used in patients with preexisting mitral valve.
