Abstract: Postprocedural atrial extrasystole (AES) frequency predicts atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI) in patients with paroxysmal AF. However, the predictive value of preprocedural AES frequency is unknown. We investigate whether preprocedural AES… read more here.

DOI: 10.1002/joa3.12597
Abstract: Acute pulmonary vein reconnection (PVR) is associated with long procedure times and large radiofrequency (RF) energy delivery during pulmonary vein isolation (PVI). Although the efficacy of high‐power PVI (HP‐PVI) has been recently established, the determinants… read more here.

DOI: 10.1002/joa3.12696
Abstract: The use of the Ablation Index (AI) software for paroxysmal atrial fibrillation (AF) has been associated with higher acute effectiveness and higher 1‐year arrhythmia freedom. There is, however, a lack of data concerning longer follow‐up.… read more here.

DOI: 10.1002/joa3.12777
Abstract: Pulmonary vein stenosis (PVS) is a severe complication of atrial fibrillation (AF) ablation resulting in narrowing of affected pulmonary veins (PVs). Interventional treatment consists of angioplasty with or without PV stenting. The optimal postprocedural antithrombotic… read more here.

DOI: 10.1002/joa3.70049
Abstract: Better outcome has been suggested for repeat procedures after atrial fibrillation (AF) ablation, when recurrence presented as organized atrial tachycardia (OAT) compared to recurrent AF. However, this contradicts the finding of more advanced atrial remodeling… read more here.
