Transaortic Access Using Vascular Graft for Transcatheter Aortic Valve Implantation

A 92-year-old man with acute heart failure due to severe aortic stenosis underwent transcatheter aortic valve implantation (TAVI). Computed tomography demonstrated severe stenosis of the right common iliac artery, occlusion of the left external iliac artery, and stenosis of the left subclavian artery. Severe calcification was observed in the sinotubular junction, which was considered a risk factor for aortic dissection with transapical TAVI using a balloon-expanding bioprosthetic valve. Therefore, transaortic (TAo) access was the only option for this high-risk surgical patient. As the maximum distance from the aortic valve annulus to the sheath insertion point was less than 60 mm, TAVI was performed transaortically using a vascular graft that extended this distance, in order to avoid sheath dislocation. Our experience demonstrates that vascular graft application is a viable option in patients with an inadequate distance between the aortic valve annulus and the puncture site in TAo-TAVI.
