目的分析磁导航系统(MNS)指导下心房颤动(房颤)导管消融的围手术期并发症。方法房颤患者144例,采用MNS指导下消融92例(MNS组);手工操作完成消融52例(手工组)。分析两组相关资料。结果所有患者均成功实施肺静脉前庭隔离消融治疗。MNS组X射线暴露时间和暴露量均较手工组减少(P<0.05)。两组发生血胸、腹股沟血肿和迷走神经反射发生率无统计学差异(P>0.05)。MNS组无严重并发症发生,手工组3例(5.8%)发生严重并发症,差异有统计学意义(P<0.05)。结论与手工消融相比,MNS指导下房颤导管消融具有更好的安全性。
Objective To analyze the perioperative complications of catheter ablation of atrial fibrillation guided by magnetic navigation system (MNS). Methods A total of 144 patients with atrial fibrillation (AF) underwent ablation of MNS under the guidance of MNS. 52 patients (manual group) were ablated by manual operation. Analysis of two related data. Results All patients were successfully treated with pulmonary vestibular vestibular ablation. X-ray exposure time and exposure in MNS group were significantly lower than those in manual group (P <0.05). There was no significant difference in incidence of hemothorax, groin hematoma and vagal reflex between the two groups (P> 0.05). No serious complication occurred in MNS group, and serious complications occurred in 3 cases (5.8%) in manual group, with significant difference (P <0.05). Conclusion Compared with manual ablation, MNS-guided atrial fibrillation catheter ablation has better safety.
