This is a single-arm clinical trial. Patients with persistent atrial fibrillation with severe atrial fibrosis are enrolled as subjects to conduct left atrial isolation by catheter ablation. Postoperative recurrence rate and other indicators are analyzed to evaluate the efficacy and safety of left atrial isolation achieved by catheter ablation in patients with persistent atrial fibrillation with severe atrial fibrosis.
