Advanced interatrial block as a predictor of atrial fibrillation following catheter ablation in the left atrium.

Abstract

We read with great interest the excellent paper by Wu et al. [1] recently published in the Journal. The authors presented a verywell designed work on the role of advanced interatrial block (IAB) predicting atrial fibrillation (AF) recurrence following catheter ablation in the left atrium (LA). The main findings were that advanced IAB and left atrial size were independent predictors of recurrence of AF after ablation. The authors properly cited our work on the value of identifying advanced IAB as a predictor of AF recurrence in many different clinical scenarios, including new-onset AF after cavo-tricuspid isthmus ablation [2,3]; however, they failed to cite and discuss the most relevant work from our group on the role of IAB and more specifically, P-wave duration as a predictor of AF recurrence after pulmonary vein isolation (PVI) [4]. In this work, we showed that the presence of pre-existent prolonged P-wave duration (PWD) is associated with an increased risk of AF recurrence after catheter ablation. Some commonalities and discrepancies between studies should be noted:
