Case report: Vein of Marshall-catheter ablation combined with left atrial appendage occlusion for treatment of atrial fibrillation.

The utilization of the one-stop strategy for treating atrial fibrillation (AF) has been on the rise, but the combination of vein of Marshall catheter ablation with left atrial appendage occlusion has been rarely reported. In this case, a 62-year-old man with persistent AF underwent a one-stop strategy that included ethanol infusion in the vein of Marshall, radiofrequency catheter ablation, and left atrial appendage occlusion. The procedures successfully achieved ablation in the vein of Marshall, pulmonary vein isolation, and left atrial appendage occlusion. The feasibility and safety of this comprehensive strategy were evaluated during a 12-month follow-up. The dynamic ECG indicated the presence of sinus rhythm, and a cerebral CT scan confirmed the absence of silent ischemia. This case highlights a novel approach to treating atrial fibrillation and demonstrates promising outcomes for patients undergoing this combined procedure.
