CONGRESS ABSTRACT

Pulsed Field Ablation (PFA) is a mainly non-thermal energy source capable of creating myocardial-selective lesions. This study evaluated efficacy and safety of its introduction into real-world clinical practice for atrial fibrillation (AF) ablation. A retrospective analysis was conducted on all consecutive patients treated with AF ablation between January 2022…

Background: Pulmonary vein isolation (PVI) remains the cornerstone of catheter ablation in persistent atrial fibrillation (PersAF), yet recurrence is frequent. Multiple adjunctive strategies have been tested with heterogeneous results. Methods: We performed a focused synthesis of major randomized controlled trials (RCTs) in PersAF comparing PVI-based catheter ablation with adjunctive…

Background The optimal ablation strategy for patients undergoing repeat catheter ablation (CA) for atrial fibrillation (AF) remains debated. Vein of Marshall ethanol infusion (VOM-EI) has been proposed to enhance substrate modification and improve long-term rhythm control, particularly in persistent AF, but its role in repeated ablations is poorly investigated….

Background Left lateral atrial ridge (LLR) is a crossroads of different tissues, known as a substrate for atrial fibrillation (AF) triggers, but also as a challenging ablation site. We previously proposed the bilateral ablation approach. Purpose The aim of this study is to assess the feasibility, safety and efficacy…

Introduction Pulmonary vein (PV) isolation durability is a major determinant of long-term success after atrial fibrillation (AF) ablation. Pulsed field ablation (PFA) has emerged as an alternative to radiofrequency (RF), potentially offering more homogeneous and durable lesions. However, real-world data comparing PV reconnection rates between these technologies at repeat…

Pulsed-field ablation (PFA) is a non-thermal ablation technology potentially more selective and safer than traditional techniques; however, the extent of lesion formation and the unintentional involvement of the left atrial (LA) posterior wall (PW) remain unclear. This study aimed to characterize PFA lesion formation after pulmonary vein isolation (PVI)…
