Outcomes of TTVI in Patients With Pacemaker or Defibrillator Leads: Data From the TriValve Registry.

Objectives: The interference of a transtricuspid cardiac implantable electronic device (CIED) lead with tricuspid valve function may contribute to the mechanism of tricuspid regurgitation (TR) and poses specific therapeutic challenges during transcatheter tricuspid valve intervention (TTVI). Feasibility and efficacy of TTVI in presence of a CIED is unclear.

Background: Feasibility of TTVI in presence of a CIED lead has never been proven on a large basis.
