Although hypertrophic cardiomyopathy is uncommon in infant and children, we have experienced a case of dexamethasone induced hypertrophic cardiomyopathy in preterm baby who had bronchopulmonary dysplasia. This patient had hyaline membrane disease. Therefore, he received prolonged mechanical ventilation that resulted in bronchopulmonary dysplasia. After we carried out dexamethasone therapy for 7 days, hypertrophic cardiomyopathy appeared in his echocardiographic finding. We discontinued dexamethasone and then, hypertrophic cardiomyopathy improved. We report this case with the review of the associated literatures.
