摘要：

A 12-year-old girl, with incessant atypical idiopathic left ventricular tachycardia, underwent successful radiofrequency ablation of ventricular tachycardia focus originating from a subepicardial site adjacent to the left coronary cusp. Ventricular tachycardia was successfully eliminated by targeting an endocardial site concordant to the epicardial site of early activation. Epicardial mapping was useful in locating an effective ablation site, and aortic root angiography was used to avoid potential injury to important structures, such as the left main coronary artery and left coronary cusp.
