Condition(s) studied
Persistent Atrial Fibrillation
Investigational drug(s) / intervention(s)
FARAPULSE™ Pulsed Field Ablation (PFA) SystemAnti-Arrhythmic Drug (AAD): Flecainide, Sotalol, Propafenone, Dofetilide, and Dronedarone
FARAPULSE™ Pulsed Field Ablation (PFA) System: Subjects will undergo a pulsed field ablation procedure using the FARAPULSE™ Pulsed Field Ablation (PFA) System for the isolation of pulmonary veins and posterior wall.
Anti-Arrhythmic Drug (AAD): Flecainide, Sotalol, Propafenone, Dofetilide, and Dronedarone: Anti-Arrhythmic Drugs (AADs) including, Flecainide, Sotalol, Propafenone, Dofetilide, and Dronedarone will be prescribed and monitored in accordance with local clinical practice and already established guideline-directed therapy for patients with persistent atrial fibrillation (AF).
Study summary
The purpose of this study is to establish the safety and effectiveness of pulsed field ablation as a first-line ablation treatment for subjects with persistent atrial fibrillation as compared to subjects who received an initial treatment with anti-arrhythmic drugs.
