Transcatheter Aortic Valve Implantation in Morphologically Complex Root Aneurysms

Performing transcatheter aortic valve implantation in the presence of aneurysmatic aortopathy is widely contraindicated but needs to be taken into account as a bailout strategy in selected patients. Deliberate preoperative assessment of measurements becomes the crucial key element in this context. After meticulous valve selection, retrograde access is obtained through the right subclavian artery additionally serving as a backup arterial cannulation site in case of conversion. Transcatheter aortic valve implantation is then performed through the transapical route. Transcatheter aortic valve implantation in complex aneurysmatic aortic morphology is feasible in highly selected patients after comprehensive preoperative evaluation. The present article describes our initial experience, safeguards, and technical details.
