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 ...
Coarctation of the aorta which is, narrowing of a section of the aorta may also be observed. [1] Again this presents an obstruction to blood flow out from the left ventricle. [3] Since there is obstruction of flow into and out of the left ventricle, the prognosis depends on the degree of obstruction and its effect on blood flow.
Interrupted aortic arch is a very rare heart defect (affecting 3 per million live births) [1] in which the aorta is not completely developed. There is a gap between the ascending and descending thoracic aorta. In a sense it is the complete form of a coarctation of the aorta. Almost all patients also have other cardiac anomalies, including a ...
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.
[1] [2] The diagnosis is suspected based on symptoms with medical imaging, such as CT scan, MRI, or ultrasound used to confirm and further evaluate the dissection. [1] The two main types are Stanford type A, which involves the first part of the aorta, and type B, which does not. [1] Prevention is by blood pressure control and smoking cessation. [1]
If untreated, severe symptomatic aortic stenosis carries a poor prognosis, with a 2-year mortality rate of 50-60% and a 3-year survival rate of less than 30%. [63] Prognosis after aortic valve replacement for people younger than 65 is about five years less than that of the general population; for people older than 65 it is about the same. [57]
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.
Artist's rendering of a branched/fenestrated EVAR in the visceral segment of the aorta above an abdominal aortic aneurysm. Thoracoabdominal aortic aneurysms (TAAA) involve the aorta in the chest and abdomen. As such, major branch arteries to the head, arms, spinal cord, intestines, and kidneys may originate from the aneurysm.
