Transcatheter Valve-In-Valve Implantation in Patients With Fluoroscopically Invisible Tricuspid Valve Prostheses.

ABSTRACT: Tricuspid bioprostheses are prone to structural valve degeneration, often requiring complex interventions. Surgical reoperation carries high morbidity and mortality, whereas transcatheter valve-in-valve implantation offers a safer alternative. However, when the tricuspid prosthesis is fluoroscopically invisible, accurate valve positioning becomes challenging. This case series presents 3 such patients successfully treated using a novel adjunctive technique. A coronary guidewire was positioned in the right coronary artery as an anatomical marker for the atrioventricular groove. Balloon pre-dilatation was then performed to delineate the bioprosthetic valve's position, guiding precise deployment of the new valve. All procedures utilized Myval prostheses and were completed without major complic
