Assessment

Primary outcomes

The incidence of major bleeding events which is defined
by ISTH(International Society of Thrombosis and Hemostasis) during and up to 12 weeks after ablation

Key secondary outcomes

Following events during and up to 12 weeks after ablation
; thromboembolic events (stroke, systemic embolism)
; Minor bleeding events which were defined as clinical bleeding events that did not fulfill ISTH criteria for major bleeding events.
; a composite of major bleeding events and thromboembolic events (stroke, systemic embolism).

Interventions/Control_1

Intervention period ; from the administration of dabigatran at the procedural day until 12 weeks after the ablation is performed

At the time of acquiring informed consent, we confirm that anticoagulation therapy is done by one of the following drugs.
; At least three weeks before the start of ablation, the patients take Apixaban 5 mg twice a day after breakfast and dinner or 2.5 mg twice a day after breakfast and dinner.
; At least three weeks before the start of ablation, the patients take Rivaroxaban 15 mg once a day after breakfast or 10 mg once a day after breakfast.
; At least three weeks before the start of ablation, the patients take Edoxaban 60 mg once a day after breakfast or 30 mg once a day after breakfast

On the day of ablation, the patients stop taking the above DOAC, take Dabigatran 110mg twice a day. Regarding ablation, we perform pulmonary vein isolation according to the method recommended by the guideline using radiofrequency catheter ablation or 28 mm cryoballoon catheter as usual, and add substrate-modification ablation to the arrhythmia as necessary.
