Main findings
In the present multicenter NHR study we investigated the ablation strategies adopted in patients with durably isolated PVs at repeat AF ablation procedures. Several ablation strategies are being performed ranging from no ablation to a single or multiple ablation strategies, with posterior wall ablation as the most prevalent approach. There was no difference in atrial arrhythmia recurrence after repeat ablation between the different strategies and compared to no re-ablation. Interestingly, these findings were observed irrespective of whether patients presented with paroxysmal or persistent AF.
