Compares treatment options for Atrial Fibrillation (AF)
Official title A Global Study Comparing Pulsed Field Ablation With Electrographic Flow Mapping Versus Posterior Wall Ablation for Persistent Atrial Fibrillation
ClinicalTrials.gov ID: NCT07187115
What this study is testing
- What it's testing
- The purpose of this study is to establish the safety of the pulsed field ablation (PFA) therapy of Pulmonary Veins and Electrographic Flow (EGF) identified extra-PV sources of atrial fibrillation (PVI + EGF ablation of sources) and to demonstrate its non-inferiority in effectiveness compared to PFA of Pulmonary Veins and LA Posterior Wall (PVI+ PWA) in the treatment of de novo symptomatic drug-refractory persistent atrial fibrillation (PersAF).
