研究目的:

本研究旨在比较经验性Marshall静脉无水酒精消融([Marshall vein ethanol infusion,MVEI],MVEI作为手术第一步,随后进行补充性射频导管消融)和按需性MVEI(MVEI将在射频导管消融不足以实现二尖瓣峡部[mitral isthmus, MI]双向阻滞时进行)在接受首次 MI 消融的持续性房颤患者中的有效性、安全性和长期临床结局。  

Objectives of Study:

This study intends to compare the efficacy, safety, and long-term outcomes between empirical Marshall vein ethanol infusion ([MVEI], MVEI as a first step followed by touch-up radiofrequency ablation [RFA]) and provisional MVEI (MVEI will be performed when RFA procedures are inadequate to achieve bidirectional mitral isthmus [MI] block) in patients with persistent atrial fibrillation (PeAF) undergoing the index MI-ablation procedure.

药物成份或治疗方案详述:

所有入组的患者将接受房颤射频消融手术。经验性MVEI组患者将在常规房颤消融术前行经验性Marshall静脉无水酒精消融,随后进行补充性射频消融,包括肺静脉电隔离、心内膜/心外膜二尖瓣峡部线性消融、左房顶部线性消融等。按需性MVEI组患者将先接受常规房颤消融,在射频消融心内膜/心外膜二尖瓣峡部仍无法实现双向阻滞时,行按需性Marshall静脉无水酒精消融。 

Description for medicine or protocol of treatment in detail:

All enrolled patients will undergo atrial fibrillation radiofrequency ablation. Patients in the empirical MVEI group will undergo empirical Marshall vein ethanol infusion prior to conventional atrial fibrillation ablation, and the RF ablation include pulmonary vein isolation, endocardial/epicardial mitral isthmus isolation, left atrial roof line isolation, etc. Patients in the provisional MVEI group will undergo conventional AF ablation first, and provisional Marshall vein ethanol infusion will be performed when conventional endocardial and/or epicardial ablation procedures are inadequate to achieve bidirectional mitral isthmus block.

干预措施:

Interventions:

组别:

经验性MVEI组

样本量:

42

Group:

Empirical MVEI Group

Sample size:

干预措施:

术中先行冠状窦选择性造影确认VOM解剖及定位。房间隔穿刺后行左房三维建模及MVEI消融前电压标测。先行MVEI消融,完成后再次行左房电压标测以对比。后行双侧肺静脉电隔离术及其他解剖学消融或心房基质改良。如消融后未转窦律,行药物复律或电复律。验证包括二尖瓣峡部线在内的各消融径线,及肺静脉-左房消融环双向传导阻滞。检查心包腔。

干预措施代码:

Intervention:

During the operation, coronary sinus angiography is performed to confirm VOM anatomy and localization. Three-dimensional modeling of the left atrium and voltage mapping before MVEI ablation are performed after transseptal puncture. MVEI ablation is performed first, and left atrial voltage mapping is performed again after completion for comparison. Bilateral PV isolation and other anatomical ablation or atrial substrate modification are performed later. If sinus rhythm is not converted after ablation, pharmacological or electrical cardioversion is performed. Verify each ablation line including mitral isthmus line and bidirectional conduction block of pulmonary vein-left atrial. Pericardial cavity is examined.

干预措施:

术中先行冠状窦选择性造影确认VOM解剖及定位。穿刺房间隔后行左房三维建模,行双侧肺静脉电隔离术及其他解剖学消融或心房基质改良;行包括二尖瓣峡部线在内的左房内膜面线性消融,必要时可于冠状窦内对应的心外膜面进行消融。如上述消融步骤仍无法实现跨二尖瓣峡部的双向传导阻滞,或无法终止二尖瓣峡部依赖性房速,则行MVEI消融。药物复律或电复律后,验证包括二尖瓣峡部线在内的各消融径线,及肺静脉-左房消融环双向传导阻滞。检查心包腔。

干预措施代码:

Intervention:

During the operation, coronary sinus angiography is performed to confirm VOM anatomy and localization. After puncturing the atrial septum, three-dimensional modeling of the left atrium was performed, bilateral pulmonary vein isolation and other anatomical ablation or atrial substrate modification are performed; endocardial linear ablation of the left atrial including the mitral isthmus line is performed, and ablation could be performed in the epicardial surface corresponding to the coronary sinus if necessary. MVEI ablation is performed if bidirectional conduction block across the mitral isthmus could not be achieved by the above ablation steps, or mitral isthmus-dependent atrial tachycardia could not be terminated. After medical cardioversion or electrical cardioversion, verify each ablation line including mitral isthmus line, and bidirectional conduction block of pulmonary vein-left atrial. Pericardial cavity is examined.
