Cardiac tumors in children are rare. Although most are histologically benign, they can be associated with life-threatening arrhythmias and sudden death. We report a 7-year-old boy, with a first episode of symptomatic tachycardia, who was found to have a left ventricular (LV) fibroma. He had a normal echocardiogram prior to an electrophysiology study, which revealed a sustained monomorphic ventricular tachycardia and a radio-opacity near the LV apex. These findings prompted a cardiac MRI, which demonstrated a discrete mass on his LV apex and free wall. Our case emphasizes that structural heart disease should be aggressively pursued in children presenting with ventricular tachycardia.
儿童心脏肿瘤较为罕见。尽管大多数在组织学上是良性的，但它们可能与危及生命的心律失常和猝死有关。我们报告一名7岁男孩，首次出现症状性心动过速，经检查发现患有左心室纤维瘤。在进行电生理研究之前，他的超声心动图正常，该研究显示持续性单形性室性心动过速以及左心室心尖附近有不透射线区。这些发现促使进行心脏磁共振成像（MRI），结果显示其左心室心尖和游离壁有一个离散性肿块。我们的病例强调，对于出现室性心动过速的儿童，应积极排查结构性心脏病。
