Multiple Coronary Stenoses of Unknown Etiology

The case of a 13-year-old girl with multiple coronary stenoses and abundant collaterals, but no risk factors, is described. She was not suspected of having ischemic heart disease until an abnormal electrocardiographic pattern was detected during a routine examination in school. All children with electrocardiographic abnormality should be carefully examined, even though they have neither symptoms nor coronary risk factors.
