Another step in transcatheter aortic valve implantation: A challenging transcatheter aortic valve implantation procedure in patient with severe peripheral arterial disease.

Approximately 25% of patients undergoing transcatheter aortic valve implantation presents significant peripheral arterial disease. The purpose of this case report was to present a feasible approach for transcatheter heart valve in a patient with peripheral arterial disease where the presence of a subclavian stent jutting in the aortic arch made the delivery system passage a challenging procedure.

Matryoshka procedure for Valve-in-Valve TAVI failure.

Valve-in-valve transcatheter valve implantation (ViV-TAVI) procedures for deteriorated bioprosthesis are an established therapeutic option for high-risk patients. The presence of the fixed sewing ring of the bioprosthesis can hamper appropriate expansion of the TAVI. We present a case of a ViViV-TAVI, as a salvage procedure for acute ViV-TAVI failure.
