Preterm Neonate With Dexamethasone-Induced Acute Hypertrophic Cardiomyopathy and Cardiogenic Shock.

This case report describes an extremely low birth weight infant, born at 26-week gestational age, who developed hypertrophic cardiomyopathy (HCM) and cardiogenic shock a few hours after administration of a small dose of dexamethasone. Although cases of steroid-induced cardiomyopathy in preterm neonates are known in literature, their adverse effects are insidious and are transient in occurrence. This is the first report of HCM and cardiogenic shock occurring acutely after administration of small-dose dexamethasone.
