Catheter Ablation in End-Stage Heart Failure with Atrial Fibrillation

N Engl J MedPublished

  • Randomised controlled trial
  • single-centre
  • open-label
  • stopped early for efficacy

Authors' conclusion

Among patients with atrial fibrillation and end-stage heart failure, the combination of catheter ablation and guideline-directed medical therapy was associated with a lower likelihood of a composite of death from any cause, implantation of a left ventricular assist device, or urgent heart transplantation than medical therapy alone.
