Abstract:
Major aortopulmonary collateral arteries can influence the postoperative course of arterial switch operation, with heart failure being the common clinical presentation. A relatively rare presentation of an aortopulmonary collateral artery in the form of persistent postoperative pulmonary hemorrhage was encountered after an uneventful arterial switch operation in a neonate with transposition of the great arteries, intact interventricular septum, and situs inversus totalis. The aortopulmonary collateral artery was coil embolized with a successful outcome.
