Abstract

Transcatheter aortic valve implantation (TAVI) has emerged as a viable alternative endovascular technique in selected patients with severe aorticstenosis, who are either inoperable or at high risk for surgical aortic valve replacement. We report a case of delayed displacement and rotation of anaortic bioprosthesis, 43 days after successful TAVI via the transfemoral approach, with the patient surviving the subsequent open heart surgery required for device retrieval.

INTRODUCTION

Transcatheter aortic valve implantation (TAVI) is now recommended as the standard of care for inoperable patients with severe aortic stenosis (AS) [1] and is also an alternative to surgical replacement in patients at high risk for open surgery [2].

Valve migration is a known complication of TAVI and occurs most frequently during implantation. We report a case of late displacement of an aortic bioprosthesis into the left ventricular outflow tract (LVOT), 43 days after transfemoral arterial implantation, and discuss some possible factors that may have contributed to the valve migration.
