Abstract:
Although feasibility and efficacy of percutaneous tricuspid valve-in-valve implantation have been established, a transtricuspid pacing or defibrillator lead might preclude this technique: lead damage can cause lead dysfunction resulting in inappropriate or inefficient pacing or shocks. In these cases, lead removal is thought to be the only option. We describe a patient who presented with rapid clinical deterioration due to tricuspid valve stenosis early after implantation of an internal defibrillator with a transvalvular shock-lead. A transvenous valve-in-valve implantation of the tricuspid valve was performed after protecting the defibrillator-lead with a custom-made covered stent. We describe the technical issues, the clinical outcome, and the evolution of lead function after implantation.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
