Key Result

Transcatheter edge-to-edge repair (TEER) is feasible and clinically beneficial for treating tricuspid regurgitation in selected patients with repaired tetralogy of Fallot.

Key Points

  • To evaluate the feasibility and clinical benefits of transcatheter edge-to-edge repair (TEER) for tricuspid regurgitation (TR) in patients with repaired Tetralogy of Fallot (rTOF).
  • Performed isolated TEER for TR in selected rTOF patients.
  • Assessed the condition of the tricuspid subvalvular apparatus before intervention.
  • TEER was found to be feasible in the studied patient group.
  • Patients showed clinical improvements post-intervention.

Structured PICO

Is transcatheter tricuspid valve edge-to-edge repair feasible and clinically beneficial in patients with repaired Tetralogy of Fallot and tricuspid regurgitation?

P
Population
Selected patients with repaired Tetralogy of Fallot (rTOF) and tricuspid regurgitation (TR) contributing to right heart failure

Intervention
Transcatheter Tricuspid Valve Edge-to-Edge Repair (TEER)

Transcatheter tricuspid edge-to-edge repair is a feasible and clinically beneficial option for managing tricuspid regurgitation in selected patients with repaired Tetralogy of Fallot.

Abstract

TR contributes to right heart failure in rTOF. The tricuspid subvalvular apparatus may be fragile; nevertheless, TEER remains feasible and clinically beneficial in selected patients.
