Captopril induced reversible acute renal failure in a premature neonate with double outlet right ventricle and congestive heart failure.

Background: captopril is well tolerated in most patients. There is no report of acute deterioration in renal function after administration of captopril in neonates with congestive heart failure secondary to congenital heart defects with large left-to-right shunts.

Methods: we report a premature neonate with double outlet right ventricle and congestive heart failure who developed acute renal failure after administration of captopril at a low dose of 0.
