Introduction: Transseptal puncture (TSP) is challenging in patients with prior percutaneous atrial septal defect (ASD) occluder. We aimed to perform a systematic review and meta-analysis of the safety and efficacy of catheter ablation for atrial fibrillation (AF) in patients with percutaneous ASD occluder. Methods: We searched PubMed, Medline, Embase, Ovid, and Cochrane for studies reporting results of AF ablation (freedom from AF, fluoroscopy/procedure time, and complications) in patients with percutaneous ASD occluders. Results: Three studies with a total of 64 patients met inclusion criteria. The success rate of TSP was 100%. All patients (but one) underwent TSP under fluoroscopic and intracardiac echocardiography guidance. Freedom from AF was achieved in 77.7% (95% confidence interval [CI]: 65.7–86.3) patients. In the subgroup analysis, comparing septal versus device puncture, no significant difference in recurrence of AF was observed (23.07% vs. 16.66%; risk ratio: 1.18; 95% CI: 0.35–4.00; p =.79, respectively). The total fluoroscopy time was not significantly different in patients with TSP via native septum or device (43.50 vs. 70.67 min; p =.44), total procedural time was significantly longer with TSP via the closure device (237.3 vs. 180 min; p =.004) compared with the native septum. There were no device dislodgement or residual interatrial shunt during the follow-up period. Conclusion: Catheter ablation for AF in patients with prior percutaneous ASD closure device is feasible and safe with favorable long-term outcomes.
