Stage II surgery for hypoplastic left heart syndrome—bidirectional Glenn: The superior vena cava (SVC) is transected and anastomosed to the pulmonary artery (PA). Cerebral and upper extremity blood passively flows to the lungs through the PA via the SVC. Oxygenated pulmonary venous blood then enters a common atrium, mixes with deoxygenated blood from the inferior vena cava (IVC), and enters the right ventricle where it is pumped through the neoaorta (NeoAo) to the systemic circulation.
