Percutaneous caval stent valve implantation: investigation of an interventional approach for treatment of tricuspid regurgitation

Abstract

In high-grade tricuspid insufficiency, percutaneous implantation of valved stents in the central venous position reduces venous regurgitation and improves haemodynamics in the animal experiment. Implantation of one or two valves in central venous position is technically feasible. Functional replacement of the insufficient tricuspid valve leads to an increase in CO. This technique expands the potential therapeutic options for patients with relevant tricuspid valve regurgitation having a high risk for open heart surgery.

Percutaneous Bicaval Valve Implantation for Transcatheter Treatment of Tricuspid Regurgitation

“…1 For inoperable patients with TR, transcatheter caval valve implantation has been suggested. 2 Herein, we report the human application and 12-month follow-up after first bicaval implantation of selfexpanding valves into the superior (SVC) and inferior (IVC) vena cava as interventional concept for severe TR. …”

Letter by Lauten et al Regarding Article, “Interventional Cardiology Perspective of Functional Tricuspid Regurgitation”

“…We experimentally investigated this approach, demonstrating feasibility and hemodynamic function of heterotopic valves. 3,4 Unpublished data even demonstrate caval valve function up to 3 months after implantation. As stated previously, this concept has several obvious advantages, including the straightforward implantation technique owing to the distance to vulnerable cardiac structures and making this an attractive approach to the interventional cardiologist.…”
