Aortic Dissection After Self-Expanding Transcatheter Aortic Valve Replacement

Scott DeRoo et al. Ann Thorac Surg Short Rep. .

Abstract

Aortic dissection after transcatheter aortic valve replacement is rare but can be managed with open surgical repair. Principles of repair are the same as in patients with spontaneous aortic dissection; however, all procedures include transcatheter aortic valve replacement explantation and subsequent aortic valve replacement. A high index of suspicion facilitates early recognition and effective surgical repair.
