(= cavopulmonary anastomosis). In this operation, the superior vena cava is connected to the right branch of the pulmonary artery. This causes the blood to flow from the arms and head directly into the lungs, bypassing the heart. The blood from the inferior vena cava enters the atrium as before and then enters the systemic circulation via the ventricle. The patient's cyanosis persists, but is less than before the operation. See also Cavopulmonary anastomosis.
