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.
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.
The Bare and Covered CP Stent video shows clearly how to implant the CP Stent in the native CoArctation of the Aorta. The CP Stent is available pre-mounted on BIB catheter. The BIB Catheter allows for the controlled expansion of the CP Stent.
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 ...
Classic for a coarctation of the aorta. Coarctation of the aorta is narrowing of the aorta. This can occur in Turner's Syndrome, (gonadal dysgenesis). Turner's Syndrome is an X-linked disorder with absence of one X-chromosome. Other exam findings of coarctation of the aorta include radio-femoral delay.
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.
Coarctation of the aorta. A congenitally narrowed aorta, due to coarctation, is often associated with a significant enlargement of the internal thoracic and ...
