研究目的:

主要目的是明确在肺静脉前庭电隔离的基础上,增加二尖瓣峡部线消融是否能提高持续性房颤手术成功率和安全性。 次要目的是比较两种手术策略在持续性房颤导管消融中的手术相关指标(如手术时间、X线曝光时间、消融时间、并发症等)的差异。  

Objectives of Study:

The main objective is to evaluate the clinical safety and efficacy of mitral isthmus ablation in patients with persistent AF who underwent first-time radiofrequency catheter ablation. The secondary objective was to compare the procedure-related parameters (e.g., procedure time, fluoroscopy time, ablation time, and complications) between the two groups for catheter ablation of persistent AF.

排除标准:

Previous intervention for atrial fibrillation (including surgical maze procedure, catheter ablation, left atrial appendage occlusion, etc.); 5. Severe organic heart disease (such as severe mitral stenosis or regurgitation, severe aortic stenosis or regurgitation, hypertrophic obstructive cardiomyopathy, dilated cardiomyopathy, restrictive cardiomyopathy, etc.); 6. Thrombus and tumor were present in the atrium; 7. Left atrium diameter > 55 mm; 8. Contraindications to the use of heparin or oral anticoagulation; 9. Creatinine clearance < 30 ml/min; 10.
