摘要
目的评价Carto三维标测系统标测、消融典型心房扑动的临床疗效。方法 14例典型心房扑动患者,采用Carto指导下右心房电解剖重建和激动顺序标测,冷盐水灌注导管消融三尖瓣峡部终止心房扑动,并通过起搏刺激验证消融线双向阻滞。观察消融即刻成功率、手术时间、消融时间和X线曝光时间以及并发症情况。通过随访,评价导管消融后远期疗效。结果 Carto指导下右房激动顺序标测证实10例为I型房扑、4例为Ⅱ型房扑。所有患者均在消融中终止心房扑动,平均手术时间(2.5±0.5)h,X线曝光时间(15±5.5)min。所有患者术中即刻均实现消融线两侧双向传导阻滞,S-A间期平均(120±15)ms。平均随访6个月,无心房扑动复发。结论 Carto指导下标测、消融典型心房扑动疗效肯定,同时可显著减少X线暴露及消融手术时间。
Objective To evaluate the clinical application of Carto system for mapping and ablation of classic atrial flutter （AF）.Methods A total of 14 patients with classic AF were completed electroanatomic reconstruction and activation sequence mapping under Carto system.AF was terminated by ablation cavo-tricuspid isthmus with irrigating ablation catheter.Bilateral conduction block along ablation lesion was identified under program stimulation.The acute success rate of ablation,operation time,fluoroscopy time and complication were observed.The long term efficacy of ablation was studied by index follow up.Results All AF were successfully activation sequence mapped and terminated during ablation in whom 10 were type Ⅰ AF and 4 were type Ⅱ AF.The operation time,fluoroscopy time and discharge time was（2.5±0.5）hrs,（15±5.5）min and（23.1±13.4）min respectively.All patients were achieved bilateral conduction block along ablation lesion with SA interval of（120±15）ms.No recurrence was observed during follow up.Conclusion Guided by Carto system for mapping and ablation of classic AF is efficient and fluoroscopy and operation time is significantly reduced.
