List the 3 stages of Norwood procedure.
Staged reconstruction of HLHS
1. Norwood - small AO and dilated PA combined to form 1 large vessel. Branch PA disconnected and shunt created btw descending AO and Pulmonary arteries
2. Hemi Fontan - SVC transected & each end sewn into RPA (Bidirectional Glen)
3. Baffles - IVC & SVC are baffled away from RA; systemic venous return doesn't enter the RA but goes directly to pulmonary arteries
