Atrial ectopic tachycardias (AET) are often resistant to medical management and can lead to a significant reduction in cardiac function. Transcatheter cryoablation, a definitive therapy, to our knowledge has yet to be described in the pediatric population. A three-year-old male presented with AET induced heart failure which persisted despite medical management. Management was complicated by worsening heart failure and propylene glycol intoxication. He underwent transcatheter cryoablation using a 3-D navigation system with an initially successful elimination of the arrhythmia. After a late recurrence (15 months) of the AET he underwent epicardial transcatheter ablation using cryotherapy with successful elimination of the arrhythmia.
房性异位性心动过速（AET）通常对药物治疗耐药，并可导致心功能显著下降。据我们所知，经导管冷冻消融作为一种确定性治疗方法，在儿科人群中尚未见报道。一名3岁男性因AET诱发心力衰竭，尽管进行了药物治疗，但心力衰竭仍持续存在。治疗因心力衰竭恶化和丙二醇中毒而变得复杂。他使用三维导航系统接受了经导管冷冻消融，最初成功消除了心律失常。AET晚期复发（15个月）后，他接受了心外膜经导管冷冻消融，成功消除了心律失常。
