Ablative Management of Persistent Atrial Fibrillation (PeAF) with Posterior Wall Isolation (PWI): Where Do We Stand? [PDF]

Journal of Cardiovascular Development and Disease, 2023
Atrial fibrillation is a diverse clinical entity, with persistent atrial fibrillation (PeAF) being particularly challenging to manage. Through this paper, we discuss notable developments in our understanding of ablative strategies for managing PeAF, with

Challenges and Outcomes of Posterior Wall Isolation for Ablation of Atrial Fibrillation [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
Background The left atrial posterior wall (PW) often contains sites required for maintenance of atrial fibrillation (AF). Electrical isolation of the PW is an important feature of all open surgeries for AF.

Biomarker response to balloon-in-basket pulsed field ablation: does posterior wall isolation matter? [PDF]

Frontiers in Cardiovascular Medicine
BackgroundA novel balloon-in-basket pulsed field ablation (BiB-PFA) catheter enables efficient pulmonary vein isolation (PVI) and allows posterior wall isolation (PWI) within the same procedure.

The Value of Adjunctive Left Atrial Posterior Wall Isolation on Clinical Outcomes in Atrial Fibrillation Patients: A Systematic Review and Meta-Analysis [PDF]

Reviews in Cardiovascular Medicine
Background: Although pulmonary vein isolation (PVI) remains the mainstream way of atrial fibrillation (AF) ablation. The left atrial posterior wall (LAPW) may contributes to the development of AF as an arrhythmogenic substrate. The efficacy of additional

Pulsed field ablation for persistent atrial fibrillation: meta-analysis of pulmonary vein isolation with or without posterior wall isolation [PDF]

Scientific Reports
Pulsed field ablation (PFA)-guided pulmonary vein isolation (PVI) has limited efficacy in treating persistent atrial fibrillation (AF) and requires additional substrate modification, but the efficacy of PVI combined with left atrial posterior wall ...

Dual-atria rotor modification: A comparative analysis of rotor modification and posterior wall isolation in patients with persistent and long-standing persistent atrial fibrillation [PDF]

Heart Rhythm O2
Background: Various methods have been devised for catheter ablation of persistent atrial fibrillation (AF). However, it remains difficult to understand the mechanism of AF and to determine the optimal method.
