Clinical Trial: A Study on the Therapeutic Value of Additional Left Atrial Posterior Wall Isolation Guided by Voltage Mapping in Persistent Atrial Fibrillation.

U.S., May 16 -- ClinicalTrials.gov registry received information related to the study (NCT07590661) titled 'A Study on the Therapeutic Value of Additional Left Atrial Posterior Wall Isolation Guided by Voltage Mapping in Persistent Atrial Fibrillation.' on April 20.

Brief Summary: This prospective, multicenter, randomized controlled study was designed to investigate the feasibility, efficacy and safety of pulsed field ablation (PFA) strategies for persistent atrial fibrillation. For patients with persistent atrial fibrillation and normal left atrial substrate, pulmonary vein isolation combined with superior vena cava isolation will be performed. For those with abnormal left atrial substrate, two strategies will be adopted: pulmonary vein i...
