干预性研究

Study type:

Interventional study

Study phase:

研究设计:

随机平行对照 

Study design:

Parallel 

研究目的:

评估肺静脉前庭放射状线性消融术式治疗阵发性房颤的远期预后和安全性。肺静脉前庭放射状线性消融术目的是疏导分流源于肺静脉的异位电流。而环肺静脉消融则只是围堵隔离肺静脉异位电流。这两种术式采用了完全不同的哲学理念。  

Objectives of Study:

To evaluate the efficacy and safety of pulmonary antrum radial-linear ablation on paroxysmal atrial fibrillation. Pulmonary antrum radial-linear ablation aims to shunt the pulmonary ectopic impulse. While circumferential pulmonary vein ablation is to isolate the pulmonary ectopic impulse. The concept of philosophy related to both the strategies is much different.

干预措施:

组别:

A组

样本量:

200

Group:

group A

Sample size:

干预措施:

肺静脉前庭放射状线性消融组: 在两侧肺静脉前庭做6-8条放射状线性消融,从肺静脉口开始,到前庭-左房交界部((此处只能记录到单纯左房电位))为止,以完成预设消融径线且房颤不被诱发为消融终点。

干预措施代码:

Intervention:

Pulmonary antrum radial-linear ablation group: six to eight radial-linear lesions were created with RF ablation from pulmonary vein orifice to pulmonary vein –left atrium junction( the site where only left atrial potential was present). The procedural end point was the completion of all the designed radial-linear lines of lesions and atrial fibrillation became noninducible.

Intervention code:

B组

样本量:

200

Group:

Group B

Sample size:

干预措施:

环肺静脉消融组: 在肺静脉前庭部只做环肺静脉消融,以实现肺静脉-左房双向传导阻滞为消融终点。

干预措施代码:

Intervention:

Circumferential pulmonary vein ablation group: the conventional circumferential pulmonary vein ablation was performed only. The procedural end point was bi-directional block between pulmonary vein and left atrium.
