Opening The Wall Between Upper Heart Chambers

Creates or enlarges an opening in the wall dividing the two upper chambers of the heart, so oxygen-rich and oxygen-poor blood can mix. It is done in infants with heart defects whose circulation depends on that mixing to keep enough oxygen reaching the body.
