We report the case of a 10-year-old girl with two episodes of light-headedness and chest pain during exercise. She had an unremarkable clinical record, physical examination, ECG, and echocardiogram. Noninvasive ischemia tests were positive, but coronary angiography was normal. Exercise stress echocardiogram revealed an exercise-induced intra-left-ventricular obstruction with a peak gradient of 78 mmHg and replicated her symptoms. After starting beta-blocker therapy her clinical status improved and no residual obstruction was detected. The authors review this unsuspected clinical condition, seldom reported in the adult population and, to our knowledge, never before in a child.
我们报告了一名10岁女孩的病例，她在运动期间出现了两次头晕和胸痛发作。她的临床记录、体格检查、心电图和超声心动图均无异常。无创缺血试验呈阳性，但冠状动脉造影正常。运动负荷超声心动图显示运动诱发的左心室内梗阻，峰值压差为78 mmHg，并重现了她的症状。开始使用β受体阻滞剂治疗后，她的临床状况有所改善，未检测到残余梗阻。作者回顾了这种未被怀疑的临床情况，这种情况在成人中很少报道，据我们所知，此前从未在儿童中报道过。
