A child with pre-ductal coarctation of the aorta may present with differential cyanosis. Prostaglandins may be given to permit the oxygenated blood and deoxygenated blood to mix by keeping the ductus arteriosus open. Fig 4. The increased systemic resistance also raises the pressure in the left atriumto be higher than the right atrium, and this causes the foramen ovale to close.[2].
