Question 5

Describe coarctation of the aorta

Answer 5

Congenital
Most likely to occur distal to left subclavian artery and lateral to ligamentus arteriosum

Causes diminished perfusion to lower peripheries as BP is so low

Heart pumps at higher prissy which could lead to cardia failure

Employ collateral circulation: arch of aorta-> subclavian aorta-> internal thoracic artery-> anterior intercostal artery -> 3-9th posterior intercostal artery (back flow)-> thoracic aorta
