Stages of repair (Please look at the pictures):
1:Norwood: RV redirected to aorta (systemic). Shunt placed from RV into pulmonary artery as well (Sano shunt). Post norwood, patient highly fluid sensitive and high risk for clotting
2: Bidirectional Glenn (4-6 months): Connect SVC to pulmonary artery, disconnect RV from PA.
3: Fontan (1.5 - 4 yrs): Connect IVC to PA. Fenestrate IVC into the RV as pressure relief for the pulmonary artery. At this point pt is VERY fluid dependent, venous return is crucial for cardiac output.
