Coarctation of the aorta (CoA) [1] [2] is a congenital condition whereby the aorta is narrow, usually in the area where the ductus arteriosus (ligamentum arteriosum after regression) inserts. The word coarctation means "pressing or drawing together; narrowing". Coarctations are most common in the aortic arch. The arch may be small in babies ...
The term coarctation is another synonym, [5] but is commonly used only in the context of aortic coarctation. [ 6 ] [ 7 ] Restenosis is the recurrence of stenosis after a procedure.
Restenosis is the recurrence of stenosis, a narrowing of a blood vessel, leading to restricted blood flow. Restenosis usually pertains to an artery or other large blood vessel that has become narrowed, received treatment to clear the blockage, and subsequently become re-narrowed.
Coarctation’s a fancy way of saying “narrowing”, so a coarctation of the aorta means a narrowing of the aorta. If we look at the heart, we’ve got the right and left atria, the right and left ventricles, the pulmonary artery leaving the right ventricle to the lungs, and the aorta leaving the left ventricle and going to to the body.
English: What is coarctation of the aorta? An aortic coarctation is a narrowing of the aorta, which is split into infant and adult forms. In the infant form, it's often accompanied by patent ductus arteriosus, and mixing of deoxygenated and oxygenated blood, whereas in the adult form, the ductus arteriosus has closed off.
[citation needed] A specific risk of open surgical repair of double aortic arch is injury to the recurrent laryngeal nerve, which can cause vocal cord paralysis. Injury to the lymphatic system can lead to postoperative chylothorax. Additional risks include lung injury, bleeding with the need for blood transfusions and wound infection.

This is so called because it is a narrowing of the aorta as a result of decreased blood flow when in foetal life. [13] As the left ventricle of the heart increases in size throughout life, the narrowing eventually dilates to become a normal size. If this does not occur, this can result in coarctation of the aorta.
