BACKGROUND: The ablation of atrial fibrillation (AF) using pulmonary vein isolation is indicated when patients do not respond favorably to medical therapy. Successful procedures are accomplished in the majority of patients, but the outcome after many years of follow-up after ablation is unknown. OBJECTIVE: To describe the long-term recurrence rate and pattern of AF after successful ablation. METHODS: A prospectively identified cohort of 445 patients who demonstrated freedom from AF for at least 1 year postablation (single procedure in 391 [87.9%]) was followed for 66.0 ± 34.0 months. Patients were seen at least annually as outpatients and underwent regular electrocardiographic monitoring. RESULTS: At 40.7 ± 27.0 months postablation, 97 (21.8%) patients experienced at least 1 episode of recurrent AF. The vast majority of events were symptomatic, and no serious clinical events were associated with AF recurrence (eg, stroke). There was a steady attrition rate reaching 16.3% and 29.8% at 5 and 10 years, respectively. In 29 patients (29.5%) of the patients, recurrences were self-limited; the remainder required either medical therapy or repeat ablation. By multivariate analysis, persistent AF (hazard ratio 3.08; P < .0001) and hypertension (hazard ratio 1.08; P = .009) were independent risk factors for the recurrence of AF. The presence of both factors placed the patient at high risk of recurrence: 37.6% at 5 years and 68.8% at 10 years. CONCLUSIONS: Over the decade after a successful ablation of AF, most patients continue to demonstrate freedom from AF. At the highest risk of very late recurrence is the subset of patients with hypertension and prior persistent AF.
