Abstract
An 80-year-old man with a supra-annular transcatheter aortic valve (TAV) prosthesis presented with severe transvalvular aortic regurgitation 18 months after the TAV replacement procedure. The authors report the first ever valve-in-valve procedure using BASILICA (bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction) in such a supra-annular TAV prosthesis. Minimal paravalvular leakage, normal coronary artery flow, and easy coronary access were seen postimplantation. (Level of Difficulty: Advanced.).
