"Gazing Into the Abyss": Transcatheter Mitral Valve-in-Valve Implantation Through a Cavernous Left Atrium

Abstract

We describe the case of a 73-year-old woman presenting with heart failure, a degenerating bioprosthetic mitral valve, and severely dilated left atrium, and highlight the role of multimodality imaging in planning transseptal transcatheter mitral valve-in-valve implantation. (Level of Difficulty: Advanced.).
