Importance: Recurrent atrial fibrillation (AF) commonly occurs after catheter ablation and is associated with patient morbidity and health care costs.
Objective: To evaluate the superiority of an augmented double wide-area circumferential ablation (WACA) compared with a standard single WACA in preventing recurrent atrial arrhythmias (AA) (atrial tachycardia, atrial flutter, or atrial fibrillation [AF]) in patients with paroxysmal AF.
Design, Setting, And Participants: This was a pragmatic, multicenter, prospective, randomized, open, blinded end point superiority clinical trial conducted at 10 university-affiliated centers in Canada.
Article Synopsis
- Atrial low voltage area (LVA) catheter ablation combined with pulmonary vein isolation (PVI) is being tested to see if it improves success rates in treating persistent atrial fibrillation (AF) compared to PVI alone.
- The study is a multicenter, randomized trial where patients will be assigned to either PVI alone or PVI plus LVA ablation, focusing on the rate of arrhythmia events over 18 months as the primary outcome.
- Secondary outcomes include safety measures, quality of life, healthcare resource use, and procedural details like ablation time and complications.*
Background: Recurrence of atrial fibrillation (AF) after a pulmonary vein isolation procedure is often due to electrical reconnection of the pulmonary veins. Repeat ablation procedures may improve freedom from AF but are associated with increased risks and health care costs. A novel ablation strategy in which patients receive "augmented" ablation lesions has the potential to reduce the risk of AF recurrence.
