Postprocedural management and follow-up strategy
Patients underwent heart rhythm evaluations using electrocardiography (ECG) or 24-hour Holter monitoring at 1-, 3-, and 6-month intervals post-discharge. Follow-up appointments were scheduled on a biannual basis thereafter. If patients experienced symptoms suggesting cardiac issues, they were encouraged to obtain an ECG. Data on MACCE were gathered biannually, either during in-person clinic visits or through telephone check-ins. AF recurrence was defined as any episode of atrial tachyarrhythmia lasting at least 30 seconds detected after the initial three-month blanking period following the ablation procedure. Decisions on continuing oral anticoagulation therapy for patients without evidence of AF recurrence post-blanking period were made in consultation with the attending electrophysiologist. For patients with a CHA2DS2-VASc score above 2, the continuation of oral anticoagulant therapy was generally recommended. After the initial three-month observation period, cessation of antiarrhythmic drugs was usually suggested. Most prescriptions for long-term medications were provided within the first year following the ablation.
