Case Summary:
This clinical vignette describes successful transcatheter aortic valve implantation (TAVI) in the largest reported annulus (1,040 mm2) using a novel 35-mm balloon-expandable valve. TAVI can be performed off-label in selected patients with a massive aortic annulus using commercially available 29-mm transcatheter aortic valves by adding additional volume; however, this risks paravalvular leak, valve embolism, and damage to bioprosthetic leaflets.
Take-Home Message:
TAVI is feasible in patients with a massive aortic annulus measuring >1,000 mm2 using Myval 35-mm balloon-expandable valve with balloon overfilling.
