NEMESIS-PFA: Investigating Collateral Tissue Injury Associated with Pulsed Field Ablation.

JACC Clinical Electrophysiology
BACKGROUND Early evidence showed reduced complications with pulsed field ablation (PFA), but non-target tissue collateral damage created by electroporation effects is poorly understood and may significantly differ between systems.

Safety and effectiveness of the first balloon-in-basket pulsed field ablation system for the treatment of atrial fibrillation: VOLT CE Mark Study 6-month results

Europace
Aims Pulsed field ablation (PFA) is a growing ablation modality for pulmonary vein isolation (PVI) in atrial fibrillation (AF) patients. This study assesses the 6-month safety and effectiveness of a novel balloon-in-basket, mapping-integrated PFA system,

Hemolysis After Pulsed-Field Ablation of Atrial Fibrillation.

Heart Rhythm
Pulsed-field ablation (PFA) offers notable advantages in atrial fibrillation (AF) ablation by selectively targeting cardiomyocytes via an irreversible electroporation mechanism, thereby minimizing damage to surrounding tissues.

Early versus late atrial fibrillation recurrence after pulsed field ablation: insights from the admIRE trial

Europace
Aims Studies have shown correlations between early recurrence (ER) and late recurrence (LR) of atrial arrhythmia after ablation with thermal technologies. This admIRE trial (NCT05293639) subanalysis aims to analyse ER vs.

Ensuring catheter-tissue contact with intra-cardiac echocardiography during pulsed-field ablation improves procedure outcome in patients with atrial fibrillation.

Heart Rhythm
BACKGROUND Catheter-tissue contact is critical in creating durable lesions during pulsed-field ablation (PFA) of atrial fibrillation (AF). OBJECTIVE We aimed to compare the reconnection rate of previously ablated targets utilizing PFA with vs without ...
