"infantile (pre-ductal) form"
"characterised by a short-segment abrupt stenosis of the post-ductal aorta"
"often accompanied by post-stenotic dilatation"
"All modalities are capable of delineating the coarctation as well as collateral vessels, the most common collateral pathway being the subclavian artery to the internal thoracic artery to the intercostal arteries (resulting in inferior rib notching) to the post-coarctation segment of the descending thoracic aorta."
"pseudo-coarctation of the aorta: elongation, narrowing or kinking with no pressure gradient or collateral formation, and no rib notching"
"Coarctations account for between 5-8% of all congenital heart defects. They are more frequent in males, M:F ratio of ~2-3:1 3."
"asymmetric T-wave inversion originating from a depressed ST segment"
"PHACE syndrome"

"adult (juxtaductal, postductal or middle aortic) form"
"The surgical techniques used in children include resection and end-to-end anastomosis, resection and extended end-to-end anastomosis, prosthetic patch aortoplasty, and subclavian flap aortoplasty 1."
"pseudo-coarctation of the aorta: elongation, narrowing or kinking with no pressure gradient or collateral formation, and no rib notching"
"usually the 4th to 8th ribs are involved; occasionally involves the 3rd to 9th ribs"
"as the 1st and 2nd posterior intercostal arteries arise from the costocervical trunk (a branch of the subclavian artery) and do not communicate with the aorta, these are not involved in collateral formation; therefore, the 1st and 2nd ribs do not become notched"
"the coarctation is distal to the origin of the left subclavian artery; therefore, collaterals form on the left"
