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.
