EnSite NavX三维电生理系统指导下环肺静脉前庭隔离导管消融治疗心房颤动

目的 探讨EnSire NavX三维电生理系统指导环肺静脉前庭隔离导管消融治疗心房颤动(房颤)的有效性和安全性.方法 在EnSite NavX三维电生理系统指导下对38例药物治疗无效的阵发性或持续性房颤患者行环肺静脉导管消融,随访观察其疗效和安全性.结果 38例患者都达到消融终点,双侧肺静脉均完全隔离.手术操作时间(233.8±31.7)min,X线曝光时间(32.5±4.7)min,左房建模时间(27.5±7.5)min.术后随访(9±3)月,单次消融的成功率为89.5%,出现并发症7.9%.结论 EnSite NavX三维电生理系统指导下环肺静脉前庭隔离导管捎融治疗房颤是一种较为有效且安全的方法.

Circumferential pulmonary vein ostial isolation for atrial fibrillation guided by EnSite NavX three-dimensional electrophysiological mapping

OBJECTIVE: To investigate the efficacy and safety of circumferential pulmonary vein ostial isolation guided by EnSite NavX three-dimensional electrophysiological mapping in patients with atrial fibrillation (AF). METHODS: Thirty-eight patients with drug refractory paroxysmal or persistent AF underwent circumferential pulmonary vein ostial isolation and were followed up to investigate the efficacy and safety of the treatment. RESULTS: All cases reached the endpoint of the ablation, and both sides of the pulmonary vein were completely isolated, with an average procedure time of 200.4-/+37.0 min, X-ray exposure time of 54.7-/+9.7 min, and three-dimensional left atrial geometry reconstruction time of 27.5-/+7.5 min. During the follow-up for 9-/+3 months, the success rate of initial ablation was 89.5%, and the incidence of procedure-related complications were 7.9%. CONCLUSIONS: Circumferential pulmonary vein ostial isolation guided by EnSite NavX three-dimensional electrophysiological mapping can be effective and safe for AF treatment.
