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".
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.
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.
Aorta: Traumatic injury [11] Incidence: Although injury to the thoracic aorta is often fatal, in 10% of cases that take longer to present, hoarseness may be the first symptom. [11] Aortic dissection [12] More commonly affects the right recurrent laryngeal nerve as the most common type of aortic dissection is type A (Figure 2). Pseudoaneurysm [13]
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 ...
Signs and symptoms depend on the specific type of defect. [3] Symptoms can vary from none to life-threatening. [7] When present, symptoms are variable and may include rapid breathing, bluish skin , poor weight gain, and feeling tired. [2] CHD does not cause chest pain. [2] Most congenital heart defects are not associated with other diseases. [3]
Acute aortic syndrome (AAS) describes a range of severe, painful, potentially life-threatening abnormalities of the aorta. [1] These include aortic dissection, intramural thrombus, and penetrating atherosclerotic aortic ulcer. [2] AAS can be caused by a lesion on the wall of the aorta that involves the tunica media, often in the descending ...
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]
