Transcatheter Aortic Valve Implantation through a Left Aortoiliac Graft

The indications for transcatheter aortic valve implantation have been increasing with the development of new-generation valves and delivery systems. Our patient, an 81-year-old man with aortic stenosis, had an existing coronary artery bypass graft and bilateral aortoiliac bypass grafts. We used the transfemoral approach through the left femoral artery and the left aortoiliac graft to successfully deploy a new-generation Edwards SAPIEN valve.Key words: Aortic stenosis, arterial disease, peripheral, heart valve prosthesis implantation/methods, transcatheter aortic valve implantationTranscatheter aortic valve implantation (TAVI) has emerged as a promising alternative to conventional aortic valve replacement for patients whose severe, symptomatic aortic stenosis is otherwise left untreated due to comorbidities and to the high operative mortality rates associated with open-heart surgery under those circumstances.¹ The first application of this method in human beings was performed in 2002 by Cribier and colleagues.² Today, there are 2 widely used valve types. These are the balloon-expandable Edwards SAPIEN transcatheter valves (Edwards Lifesciences LLC; Irvine, Calif) and the self-expanding CoreValve® valves (Medtronic CV Luxembourg S.a.r.l.; Luxembourg). The first-generation Edwards SAPIEN valve is approved for use in the United States, but the latest generations of both valves are awaiting approval.
