Persistent Atrial Fibrillation Clinical Trial
Official title:
A Prospective Randomized Multicenter Global Study Comparing Pulsed Field Ablation (PFA) Versus Anti-Arrhythmic Drug (AAD) Therapy as a First Line Treatment for Persistent Atrial Fibrillation
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.
This is a prospective, randomized, multi-center, global, pivotal Investigational device exemption (IDE) study. Subjects with persistent atrial fibrillation will be randomized to either pulsed field ablation (PFA) or Versus Anti-Arrhythmic Drug (AAD) treatment. Subjects randomized to PFA treatment will undergo percutaneous ablative pulmonary vein isolation (PVI) and left atrial posterior wall isolation (PWI) using the FARAWAVE™ PFA Catheter (first-line ablation cohort). Subjects randomized to AAD treatment will be prescribed and monitored in accordance with local clinical practice and already established guideline-directed therapy for patients with persistent atrial fibrillation (AF). Cardioversion is recommended during the initiation of antiarrhythmic drugs for subjects who are not in sinus rhythm. In the case of clinical inefficacy, the AAD dose will be up-titrated to the maximum tolerated dose. Thereafter, a change to a second or to a third AAD should be undertaken, insofar as the subject remains within the blanking period, with the goal to completely suppress AF episodes ≥ 30 seconds in duration. It is advisable to perform cardioversion with each dose titration or when changing the AAD regimen. If AAD treatment is proven to be ineffective or intolerable outside of the blanking period, subjects can undergo subsequent ablation therapy and be considered part of the "delayed ablation cohort". ;
