After this operation is done
all of the blood coming from the upper body is diverted to the
lungs so more pink blood is coming back from the lungs to the
left side of the heart.
However, all the blood coming
back from the lungs is still going to the left side of the heart,
crossing the Atrial Septal Defect (ASD), and mixing with the
blue blood in the Right Atrium and Right Ventricle.
