Our aim was to investigate the association between post-procedural burden of supraventricular ectopic complexes (SVEC) and the risk of long-term atrial fibrillation (AF) recurrence. METHODS AND RESULTS: A total of 125 patients undergoing catheter ablation for AF were included. Patients underwent 7-day Holter recordings immediately post-procedural. The number of SVEC in post-procedural Holter recordings was categorized into quartiles: 0-72, 73-212, 213-782 and ≥ 783 SVEC/day. Long-term AF recurrence was defined as a combined endpoint of AF ≥ 1 min during follow-up Holter recordings, cardioversion or hospitalization for AF after a 3-month blanking period and within 24 months of follow-up. High post-procedural supraventricular ectopy burden was associated with an increased risk of long-term AF recurrence in a dose-dependent manner (≥ 783 SVEC: HR 4.6 [1.9-11.5], P < 0.001) irrespective of AF recurrence during the blanking period or other risk factors. In patients with early AF recurrence < 90 days after catheter ablation ectopy burden was also highly predictive of long-term AF recurrence (SVEC ≥ 213: HR 3.0 [1.3-6.7], P = 0.007). Correspondingly, patients with early AF recurrence but low ectopy burden remained at low risk of long-term AF recurrence after the blanking period. CONCLUSION: Our results indicate that post-procedural ectopy burden is highly associated with long-term AF recurrence and could be a potent risk marker for selection of patients for early re-ablation. Development of future ablation risk stratification and strategies should include focus on post-procedural ectopy burden."}
