NCT05883722

Brief Summary

Persistent atrial fibrillation (PerAF) can induce right atrial (RA) enlargement. Our previous study demonstrated patients with PerAF and RA enlargment may benefit from adjunctive RA ablation. Therefore, we conduct this multicenter, prospective, randomized study to confirm the value of adjunctive RA ablation.

Outcome Measures

Primary Outcomes (1)

  • Atrial fibrillation recurrence

    any AF episodes lasting more than 30 seconds after the blanking period without anti-arrhythmic drugs at 12 months after a single procedure.

    12 months

Secondary Outcomes (1)

  • Atrial fibrillation/atrial tachycardia recurrence

    12 months

Study Arms (2)

RA group

EXPERIMENTAL

The RA group received adjunctive right atrial ablation in addition to left side ablation.

Procedure: Catheter ablation

Control group

ACTIVE COMPARATOR

The control group received left side ablation only.

Procedure: Catheter ablation

Interventions

The ablation approach includes: pulmonary vein isolation, left side linear ablation, left side driver ablation and right atrial driver ablation

Control groupRA group
