Balloon-Expandable TAVR Prosthesis Dislocates Into the Ascending Aorta.

ABSTRACT

This case report underlines the complexity of the transcatheter aortic valve replacement (TAVR) procedure where rare complications sometimes are inevitable, even in experienced hands. Supra-annular dislocation of the balloon-expandable prosthesis was caused by loss of capture of the temporary transvenous pacemaker lead and treated successfully by retracting it towards the abdominal aorta. (Level of Difficulty Advanced.).
