The right pulmonary arterycame directly off the truncal vessel, whereas the left pulmonary artery wasconnected to the aortic arch via a stenotic ductus or ductus- like vessel.The preoperative pulmonary blood flow distribution was 94% on the rightversus 6% on the left side. The underperfusion of the left lung may havebeen related to pulmonary hypoplasia due to long lasting stenosis at theleft pulmonary artery take off.
