Medical therapy and anticoagulation management
All AADs were stopped for at least 5 half-lives before CA (amiodarone
was discontinued for at least 1 month). After CA, all patients received
NOACs or warfarin for at least 2 months. A type I or III antiarrhythmic
drug would be prescribed for eligible patients after ablation for 3
months. After the first 3 months of the blanking period, the choice of
continuing anticoagulant was left to the physician’s discretion. For
patients with any atrial tachyarrhythmia episode, anticoagulant therapy
was recommended if the CHA2DS2-VASc
score was ≥ 2.
