Prophylactic Pulmonary Vein Isolation During Atrial Flutter Ablation

Resumen breve

Pulmonary vein isolation (PVI) via catheter ablation has been successfully employed for years to treat symptomatic atrial fibrillation (AF). Moreover, PVI has not been used as a prophylactic intervention even in groups known to be high-risk for the future development of AF. Preliminary studies, including our pilot PREVENT AF I randomized trial, suggested that prophylactic PVI may be effective at reducing new onset AF and overall AF burden in atrial flutter (AFL) patients. This is a multicenter single-blind randomized controlled trial, "Prophylactic Pulmonary Vein Isolation During Atrial Flutter Ablation" (PREVENT AF II) to determine if PVI in conjunction with AFL ablation for patients with typical AFL results in a significant reduction in cardiac events and healthcare utilization.
