Focal atrial tachycardia with frequencies up to 200/min in an 11-year-old girl had been resistant to drugs over a period of 5 years. An electrophysiological study demonstrated a left atrial ectopic tachycardia. Intraoperative epicardial mapping localized the automatic focus at the base of the left atrial appendage. Excision of the appendage and cryoablation of the adjacent area were performed using cardiopulmonary bypass. Histological examination of the excised tissue showed no specific alterations aside from islets of fatty tissue. The girl has been in sinus rhythm and has shown no tachycardias during the 6 months following the operation. Review of the literature covering 17 cases of right and 12 cases of left atrial focal tachycardia indicates excision of the atrial tissue in combination with cryoablation to be the treatment of choice to ensure success.
一名11岁女孩的局灶性房性心动过速频率高达200次/分钟，在5年的时间里对药物治疗无效。一项电生理研究显示为左房异位性心动过速。术中的心外膜标测将自动兴奋灶定位在左心耳基部。使用体外循环对心耳进行切除并对相邻区域进行冷冻消融。切除组织的组织学检查显示，除了脂肪组织小岛外，没有特定改变。该女孩术后6个月一直处于窦性心律，未出现心动过速。对涵盖17例右房和12例左房局灶性心动过速的文献回顾表明，切除心房组织并结合冷冻消融是确保成功的首选治疗方法。
