Hydrocortisone induced hypertrophic cardiomyopathy.

A preterm infant developed recurrent, hypertrophic obstructive cardiomyopathy (HOCM) on administration of steroids which resolved after discontinuation of the drug. Following a course of hydrocortisone for treatment of broncho-pulmonary dysplasia, echocardiography showed left ventricular hypertrophy with outflow tract obstruction, resolving on stopping the drug, only to recur after a second course.
