Right to Left
Direction of blood flow AFTER birth
Left to Right
Increased Pulmonary Blood Flow
ASD, VSD, PDA
Most common CHD
VSD
Systemic pressure in the LV is transferred to the R side of the heart. This increases pressure in the pulmonary vasculature, which increases pressure in the lungs reversing blood flow from R to L. (Reverse shunting)
