Transcatheter Tricuspid Valve-in-Valve and Valve-in-Ring Implantation for Degenerated Surgical Prosthesis

With explosive growth in the field of transcatheter therapies in recent years, transcatheter valve-in-valve implantation has rapidly emerged as a viable, low-risk alternative to high-risk redo surgical interventions. The authors review the fundamental clinical principles of transcatheter tricuspid valve-in-valve and valve-in-ring implantation as pertinent to the procedural steps and technique.
