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.
