People who have had a coarctation of the aorta are likely to have bicuspid aortic valve disease. Between 20% and 85% of patients are affected by this disease. Bicuspid aortic valve disease is a big contributor to cardiac failure, which in turn makes up roughly 20% of late deaths to coarctation patients. [24]
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.
Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is forced to work harder than normal.
Coarctation of the aorta is also a known risk factor, [11] as is arteriovenous malformation. [14] Genetic conditions associated with connective tissue disease may also be associated with the development of aneurysms. [11] This includes: [18] autosomal dominant polycystic kidney disease, neurofibromatosis type I, Marfan syndrome,
Patients who have suffered aortic dissection are at risk of Aortic aneurysm formation at the site of the dissection, thought to be due to weakening of the aortic wall. [43] The risk of this aneurysm degeneration is 10 times higher in individuals who have uncontrolled hypertension, compared to individuals with a systolic pressure below 130 mmHg.

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 ...
