Research Article: Left atrial posterior wall isolation using pulsed-field ablation: procedural characteristics, safety, and mid-term outcomes
Introduction:
Pulmonary vein isolation (PVI) is an effective treatment option for patients with paroxysmal atrial fibrillation (AF). For patients with persistent AF, long-term success of PVI is limited [1]. It has been increasingly recognized that persistent AF initiation and maintenance of AF may depend on mechanisms outside the pulmonary veins (PV). Therefore, improved ablation strategies and techniques for these patients are needed. Non-pulmonary vein ablation targets such as posterior wall (PW) isolation (PWI) have been…
