Balloon-Assisted Valve Tracking: Atraumatic Retrieval of a Ventricularized Transcatheter Aortic Valve Prosthesis.

We report a novel percutaneous approach for the retrieval of a migrated balloon-expandable transcatheter aortic valve (TAVR) that: 1) minimizes interaction with the unstable valve; 2) stabilizes it on an arteriovenous rail; and 3) minimizes vascular trauma. A 90-year-old gentleman underwent
