Clinical Trial: Efficacy and Safety of Individualized Pulsed Field Ablation Guided by Pulmonary Vein Antral Substrate Mapping for Atrial Fibrillation: A Prospective, Single-Center, Single-Arm Study

U.S., Oct. 20 -- ClinicalTrials.gov registry received information related to the study (NCT07880262) titled 'Efficacy and Safety of Individualized Pulsed Field Ablation Guided by Pulmonary Vein Antral Substrate Mapping for Atrial Fibrillation: A Prospective, Single-Center, Single-Arm Study' on Oct. 11.

Brief Summary: This study will adopt a prospective, single-center, single-arm research design, enrolling 120 patients with paroxysmal or persistent atrial fibrillation who are scheduled to undergo catheter ablation for the first time. Individualized pulsed electrical field pulmonary vein isolation will be performed under the guidance of pulmonary vein vestibular stromal mapping. By recording the distribution characteristics of abnormal strom...
