A four-and-a-half-month-old infant suffered sudden circulatory collapse early in the course of a brief febrile illness. The electrocardiogram initially appeared normal; an abrupt change indicative of extensive myocardial infarction occurred following stabilization. Coronary arterial anatomy and flow by echocardiography and angiography were normal except for the finding of single origin of the entire coronary system from the left sinus of Valsalva. Gallium 67 myocardial imaging was positive for an inflammatory process, and the diagnosis of myocarditis was supported. This is the first case, to the authors' knowledge, of myocarditis simulating myocardial ischemia in an infant of an age in which anomalous origin of the left coronary artery from the pulmonary artery is a recognized cause for myocardial infarction.
一名4个半月大的婴儿在一场短暂发热性疾病病程早期突然发生循环衰竭。心电图最初显示正常；病情稳定后出现提示广泛心肌梗死的突然变化。除了整个冠状动脉系统均起源于左冠窦这一发现外，超声心动图和血管造影显示冠状动脉解剖结构和血流正常。镓67心肌显像显示炎症过程呈阳性，支持心肌炎的诊断。据作者所知，这是首例在婴儿期出现类似心肌缺血的心肌炎病例，而在该年龄段，左冠状动脉起源于肺动脉异常是公认的心肌梗死病因。
