while preferential blood flow to the right pulmonary artery has been described in transposition of the great arteries with or without obstruction of the left ventricular outflow tract, this disparity of pulmonary blood flow is not present in newborns.1 We report a newborn with transposition in whom there was discontinuity of the pulmonary arteries and ductal blood supply to the left pulmonary artery. To our knowledge, this entity has not been described in newborns with transposition of the great arteries {S,D,D}.
