Coarctation of the aorta (CoA), a congenital narrowing of the transverse and proximal descending aortic arch, may present as an isolated defect or in association other CHD and most individuals with isolated CoA now undergo successful catheter-based or surgical therapy and live into adulthood ..
Whereas, surgical management is preferred in the neonate due to lower risk of recoarctation and/or aneurysm formation, isolated CoA presenting later in childhood and adulthood is often amenable to percutaneous intervention.
Most individuals with isolated coarctation of the aorta (isolated CoA) undergo successful catheter-based or surgical therapy and live into adulthood.
Coarctation of the aorta is usually diagnosed after the baby is born. How early in life the defect is diagnosed usually depends on how mild or severe the symptoms are.
Coarctation of the aorta is a narrowing of the aorta, most commonly occurring just beyond the left subclavian artery. However, it can occur in various other locations of the aortic arch or even in the thoracic or abdominal aorta.
