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 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’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.
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 ...
Aneurysm of the aortic sinus, also known as the sinus of Valsalva, is a rare abnormality of the aorta, the largest artery in the body.The aorta normally has three small pouches that sit directly above the aortic valve (the sinuses of Valsalva), and an aneurysm of one of these sinuses is a thin-walled swelling.
[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]
The diagnosis of Arterial Tortuosity Syndrome is established in a person with (1) generalized arterial tortuosity and (2) positive molecular genetic testing that identifies a pathogenic mutation in the SLC2A10 gene. [9] Generalized arterial tortuosity can be identified through the following: [citation needed] Physical examination; Echocardiogram
The arch is typically spared from the aneurysmal process, though it may involve the entire ascending aorta. The ectatic aorta may experience dissections. Dissections of the ascending aorta are typically tiny, confined, and restricted. Aortic rupture can happen even if there is no dissection. [3]
