Cranial Dislocation of Infrarenal Aortic Endoprostheses During Transcatheter Aortic Valve Replacement.

This report describes the complexity of transcatheter aortic valve replacement in which rare complications sometimes occur, even at experienced centers. This is a case of cranial migration of an infrarenal aortic aneurysm endograft while advancing the balloon-expandable prosthesis through the infrarenal aorta, which was subsequently successfully treated by deploying a thoracic endoprosthesis after deployment of the aortic valve bioprosthesis.
