Study phase:

研究设计:

病例对照研究 

Study design:

Case-Control study 

研究目的:

目前采用Watchman左心耳封堵器进行房颤一站式手术的策略包括先消融后封堵及先封堵后消融,但目前尚无对两者进行比较的研究。本研究通过对符合手术适应证的患者进行随机分组,对其采用先封堵或先射频的策略进行手术,对比不同一站式手术策略对左心耳封堵及房颤射频消融疗效、手术安全性及临床结局的影响。  

Objectives of Study:

The current strategies for the combined procedures of catheter ablation and left atrial appendage closure (LAAC) with the Watchman device in patients with atrial fibrillation are either ablation first or LAAC first. However, no study comparing the two strategies has been reported yet. The aim of this randomized study is to investigate the impact of the two combined strategies on the procedural efficacy, safety and clinical outcomes.
