Optimal Ablation Strategies for Persistent Atrial Fibrillation With Heart Failure: Three-Year Follow-Up of a Prospective Multicenter Randomized Trial

Circ Arrhythm ElectrophysiolPublished

  • multicenter, randomized controlled trial

Authors' conclusion

Electrogram-anatomic ablation provides superior long-term rhythm control, reduces cardiovascular events, and improves symptoms in patients with persistent AF and HF, regardless of ejection fraction.

Study context

Population
Patients with persistent atrial fibrillation (AF) and heart failure (HF), including HF with reduced ejection fraction (ejection fraction ≤40%) and HF with preserved ejection fraction (ejection fraction >40%)randomized equally, 100 patients in each group
Participants
300 patients
Comparison
anatomic-guided ablation, electrogram-guided ablation, and extensive electrogram-anatomic-guided ablation
  • anatomic-guided ablationn = 100
  • electrogram-guided ablationn = 100
  • extensive electrogram-anatomic-guided ablationn = 100
Primary endpoint
Coprimary: (1) composite of cardiovascular death or HF-related hospitalization/urgent visit; (2) maintenance of sinus rhythm
Follow-up
36 months

Primary result

As reported in the abstract

Composite end point

Sinus rhythm maintenance

Secondary outcomes

AF burden <1%, New York Heart Association class, 6-minute walk test, NT-proBNP

Consistent improvements were observed

Subgroups: HF with reduced ejection fraction and HF with preserved ejection fraction

These trends were consistent in both subgroups
