1. Purpose of the study
1) To explore clinical recurrence associated clinical factors including age, sex, clinical, electrophysiological, anatomical, imaging, and serologic characteristics.
2) To develop simulation model to predict clinical recurrence and the efficacy of catheter ablation 2. Scientific evidence of the study
- In atrial fibrillation patients, the maintenance of normal sinus rhythm showed significant reduction of mortality.
- drug therapy with anti-arrhythmic drug showed many complications and side effect, thus non-drug therapy such as catheter ablation is developed.
- catheter ablation has been performed for 10years world-wide, and showed superior treatment outcome compared with drug therapy.
- clinical outcome after catheter ablation is affected not only by age, sex and underlying disease, but also by electrophysiologic, imaging, serologic and electroanatomical remodeling of the heart. However, there are few studies concerning these multifactorial variables.

Yonsei AF Cohort
Patients with atrial fibrillation who undergoing catheter ablation of atrial fibrillation
- Clinical recurrence of atrial fibrillation (AF) after catheter ablation [ Time Frame: Participants will be followed for 5 year after catheter ablation ]We defined recurrence of AF as any episode of AF or atrial tachycardia lasting longer than 30 sec. Patients were asked to attend scheduled outpatient follow-up appointments 2, 6, 12, 18, 24, 36, 48 and 60 months after catheter ablation.
