Ventricular arrhythmias occur in up to 13.5% of patients after tetralogy of Fallot repair. We describe a patient with a 30-year history of recurrent ventricular tachycardia, which followed the surgical repair of tetralogy of Fallot. Findings at electrophysiological study were consistent with reentry involving an area of slow conduction in the right ventricular outflow tract. Following the transcatheter application of radiofrequency energy in the right ventricular outflow tract, ventricular tachycardia could no longer be induced and has not occurred spontaneously during follow-up (28 months). Thus, transcatheter radiofrequency ablation is an acceptable therapeutic option in some patients with ventricular tachycardia after the surgical repair of tetralogy of Fallot.
法洛四联症修复术后，高达13.5%的患者会出现室性心律失常。我们描述了一名有30年复发性室性心动过速病史的患者，该患者在法洛四联症手术修复后出现这种情况。电生理研究结果与涉及右心室流出道缓慢传导区域的折返一致。在右心室流出道经导管应用射频能量后，室性心动过速不再能被诱发，且在随访（28个月）期间未再自发发生。因此，经导管射频消融对于一些法洛四联症手术修复后出现室性心动过速的患者来说是一种可接受的治疗选择。
