ICD-11 definition : A congenital cardiovascular malformation in which there is a discrete luminal narrowing
of the junction between the aortic arch and the descending aorta. Coarctation of the
aorta generally indicates a narrowing of the descending thoracic aorta just distal
to the left subclavian artery. However, the term may also be accurately used to refer
to a region of narrowing anywhere in the thoracic or abdominal aorta.;
