The haemodynamic molding theory suggests that a reduction in foetal blood flow causes hypoplasia and coarctation of the aortic arch. Twenty-five to 50% of infants diagnosed with coarctation have hypoplasia of the arch without haemodynamically significant narrowing and/or pressure gradient across the narrowed segment.ue to similarities in the clinical and imaging features of hypoplastic aortic arch and pseudocoarctation of aorta, they may be mistaken for true coarctation leading to unnecessary investigations.
No one knows what causes optic nerve hypoplasia or septo-optic dysplasia. Some people who have it have mothers who were very young when they were born. More children are born with septo-optic dysplasia in areas where food is grown. Maybe the poison used to kill bugs on farms also makes the optic nerve stop growing.
