coil closure of isolated aortopulmonary collaterals in an infant presenting with recurrent lower respiratory tract infection

Isolated major aortopulmonary collaterals are rare in healthy term neonates or infants without congenital heart disease; only a few cases have been reported with heart failure or recurrent lower respiratory tract infection in an otherwise structurally normal heart and there is no consensus about their treatment. we report a case with repeated pneumonia, failure to thrive, pulmonary hypertension, and shift of heart to right which is successfully managed by stage coil closure of collaterals.
