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 ...
There are two forms of aortic coarctation to be familiar with, an “infant” form and an “adult” form. With the infant form, which accounts for about 70% of cases, the coarctation comes after the aortic arch, which branches off to the upper extremities and to the head, and before the ductus arteriosus.
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.
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 ...
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.
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.
Coarctation of the aorta (CoA) – Narrowing of the aorta, typically of the aortic arch and is classically found in Turner syndrome. A "complete" coarction is called an interrupted aortic arch. Cor triatriatum – A membrane that divides one of the atria results in "three" atria (hence "triatriatum"). This tends to affect the left atrium more ...
Right-sided aortic arch is a rare anatomical variant in which the aortic arch is on the right side rather than on the left. During normal embryonic development, the aortic arch is formed by the left fourth aortic arch and the left dorsal aorta.
