A 13-year-old boy had recurrent ventricular tachycardia following surgical correction of tetralogy of Fallot. Pharmacological management with multiple antiarrhythmic drugs failed, and the patient underwent electrophysiological evaluation. A reentrant tachycardia involving a slowly conducting region in the left ventricular outflow tract was demonstrated. We performed radiofrequency catheter ablation after identifying the essential components of the reentrant circuit. The ventricular tachycardia could no longer be induced and did not recur spontaneously during a 13-month follow-up.
一名13岁男孩在法洛四联症手术矫正后反复出现室性心动过速。使用多种抗心律失常药物进行药物治疗失败，该患者接受了电生理评估。结果显示存在一种涉及左心室流出道缓慢传导区域的折返性心动过速。在确定折返环路的关键组成部分后，我们进行了射频导管消融。室性心动过速不再能被诱发，并且在13个月的随访期间未再自发复发。
