NCT03777631

Brief Summary

Catheter ablation (CA) has been reported to reduce risk of stroke in patients with nonvalvular atrial fibrillation (NVAF) in retrospective studies, but risk and benefit of CA has not been well elucidated in NVAF with recent cerebral infarction in prospective randomized trials.

Outcome Measures

Primary Outcomes (1)

  • Composite of recurrence of cerebral infarction, systemic embolism, all-cause death, hospitalization for heart failure.

    Composite of recurrence of cerebral infarction, systemic embolism, all-cause death, hospitalization for heart failure.

    Up to 6 years

Secondary Outcomes (10)

  • Recurrence of cerebral infarction

    Up to 6 years

  • Systemic embolism

    Up to 6 years

  • All-cause death

    Up to 6 years

  • Cardiovascular death

    Up to 6 years

  • Hospitalization for heart failure

    Up to 6 years

  • +5 more secondary outcomes

Other Outcomes (3)

  • Incidence of treatment-emergent adverse events (safety and tolerability)

    Within 1 month after CA

  • Incidence of all adverse events, not restricted to CA maneuver-related adverse events

    Within 1 month after CA

  • Drug reaction to edoxaban

    Up to 6 years

Study Arms (2)

Standard medical therapy group

NO INTERVENTION

The preferred anticoagulant is edoxaban. Antiarrhythmic drugs are administered as needed for the patient by well-trained cardiologists.

Catheter ablation group

ACTIVE COMPARATOR

Catheter ablation (CA) should be performed within 1-6 months from the onset of cerebral infarction. CA is based on pulmonary vein isolation, with atrial ablation as required. For conducting CA by a trained and experienced cardiologist, only institutions in which performed \>100 CA annually were participated in the present study in principle.

Procedure: Catheter ablation

Interventions

CA should be performed within 1-6 months from the onset of cerebral infarction. CA is based on pulmonary vein isolation, with atrial ablation as required.
