Valvular & structural heart diseaseCohort study
Outcomes of Entrapped Right Ventricular Pacing or Defibrillator Leads Following Transcatheter Tricuspid Valve Replacement
- Multicentre observational cohort study
- 3 centres
- consecutive patients
Authors' conclusion
Following TTVR, most with entrapped RV leads remain free of lead-related complications.
Study context
- Population
- Patients with a cardiac implantable electronic device (CIED) and transvenous right ventricular (RV) lead undergoing EVOQUE transcatheter tricuspid valve replacement (TTVR)of 146 EVOQUE TTVR
- Participants
- 52 patients
- Outcome
- Nature and incidence of major lead-related complications after TTVR
Main finding
As reported in the abstract

Observational data: associations, not effects.
Secondary outcomes
Other lead-related adverse events in complication-free patients with follow-up >30 days · 356 [196-965] days
- No other lead-related adverse events among 46 complication-free patients
Paravalvular leak mild or less · 30 days post-TTVR
- Paravalvular leak mild or less, patients of 48
- 47 (98%)
Lead parameter changes after entrapment (33 complication-free patients with ≥1 CIED interrogation >30 days) · 424 [182-1,006] days
- Significant decrease in lead impedance and increase in capture threshold on final lead assessment
- No additional patients required lead revision
