In D-transposition of the great arteries (complete transposition), systemic venous blood returns to the right atrium, from which it goes to the right ventricle and then to the arota. Pulmonary venous blood returns to the left atrium, from which it goes to the left ventricle and then to the pulmonary artery. Survival is possible only if there is a communication between the two circuits, such as a patent ductus arteriosus.
