A healthy 17-year-old boy was admitted to the emergency department presenting with a pressure-like sternal pain that started during exercise. His physical examination was normal. Twelve-lead ECG and transthoracic echocardiogram suggested a myocardial infarction. The patient was submitted to an invasive coronary angiography, which revealed a distal occlusion of the left anterior descending artery, due to a spontaneous coronary artery dissection. A balloon angioplasty was performed, with good results. Aetiological study did not discover any pathologic condition. Chest pain in paediatric age is a frequent complaint, despite not being usually caused by a serious condition. However, it is important to remember warning signs in order to diagnose life-threatening diseases, as soon as possible.
