Incisional sustained tachycardias are frequent in patients who have undergone a surgical repair of interatrial defect. A 43-year-old woman with drug refractory, highly symptomatic, persistent atrial tachycardia in the last year, was referred to our unit for catheter ablation. The patient had undergone a cardiac operation for repairing interatrial secundum ostium type defect with a patch five years before. A previous radiofrequency ablation procedure had been performed for common atrial flutter. We describe a case of incisional atrial tachycardia ablation guided by the new EnSite NavX system equipped with a new electroanatomic mapping system.
切口性持续性心动过速在接受房间隔缺损手术修复的患者中很常见。一名43岁女性，去年患有药物难治性、症状严重的持续性房性心动过速，被转诊至我院进行导管消融治疗。该患者五年前曾接受过心脏手术，用补片修复继发孔型房间隔缺损。此前曾因常见房扑进行过一次射频消融手术。我们描述了一例在配备新型电解剖标测系统的新型EnSite NavX系统引导下进行切口性房性心动过速消融的病例。
