Clinical Trial: Pulsed-Field Ablation Vs. Radiofrequency Ablation CombIned with Vein of Marshall Ethanol Ablation on Mitral Isthmus Block and Clinical Outcomes in Persistent Atrial Fibrillation

U.S., March 11 -- ClinicalTrials.gov registry received information related to the study (NCT06866704) titled 'Pulsed-Field Ablation Vs. Radiofrequency Ablation CombIned with Vein of Marshall Ethanol Ablation on Mitral Isthmus Block and Clinical Outcomes in Persistent Atrial Fibrillation' on March 01.

Brief Summary: Atrial fibrillation (AF) is one of the most common clinical arrhythmias, and catheter ablation serves as a critical therapeutic approach. For persistent atrial fibrillation, several proposed ablation strategies-including the 2C3L technique, BOX lesion sets, and substrate modification-remain highly controversial regarding long-term success rates. Multiple studies suggest that linear ablation beyond pulmonary vein isolation (PVI) ...
