Background: The posterior left atrium is an arrhythmogenic substrate that contributes to the
initiation and maintenance of atrial fibrillation (AF); however, the feasibility, safety, and …

In the last three decades, ablation of atrial fibrillation (AF) has become an evidence-based
safe and efficacious treatment for managing the most common cardiac arrhythmia. In 2007 …

Objectives This study explored whether complete electrical isolation of the left atrial (LA)
posterior wall improves the rhythm outcome of catheter ablation of persistent atrial fibrillation …

Background Electrical posterior wall isolation (PWI) is increasingly being used for the
treatment of patients with atrial fibrillation (AF). Few data exist on the durability of PWI using …

Background: Persistent atrial fibrillation (AF) can change to paroxysmal AF after
antiarrhythmic drug medication and cardioversion. We investigated whether electrical …

Ablation of non-pulmonary vein (PV) triggers is an important step to improve outcomes in
atrial fibrillation ablation. Non-pulmonary vein triggers typically originates from predictable …

Background: The efficacy of cryoballoon pulmonary vein isolation (Cryo-PVI) is equivalent to
that of radiofrequency pulmonary vein isolation in patients with paroxysmal atrial fibrillation …

Introduction The left atrial (LA) posterior wall (LAPW) has been targeted to improve the
clinical outcomes in patients with persistent atrial fibrillation (PersAF). This study aimed to …

Background Recurrences of atrial fibrillation (AF) after ablation have been attributed to
conduction gaps and nontransmural ablation lesions. Objective The purpose of this study …

Abstract Aims The safety of Ablation Index (AI)-guided 50 W ablation for atrial fibrillation (AF)
remains uncertain, and mid-term clinical outcomes have not been described. The interplay …
