Pulmonary vein antrum isolation is the most effective rhythm control strategy in patients with paroxysmal AF. However, catheter ablation of non-paroxysmal AF has a lower success rate, even when persistent isolation of pulmonary veins (PVs) is achieved. As a result of arrhythmia-related electophysiological and structural changes in the atria, sites other than the PVs can harbour triggers. These non-PV triggers contribute to AF relapse. In this article, we summarise the rationale and current evidence supporting the arrhythmogenic role of non-PV triggers and our ablation approach to patients with non-paroxysmal AF.
