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.
