- Aortic arch: The second section of the aorta following the ascending aorta. As it continues from the heart, it gives off the brachiocephalic trunk, and the left common carotid and subclavian arteries. The brachiocephalic trunk splits to form the right subclavian and the right common carotid arteries, which supply blood to the right arm and the right side of the neck and head.

- 1 Aortic aneurysms that occur in the chest area are called thoracic aortic aneurysms and can involve the aortic root, ascending aorta, aortic arch or descending aorta. 2  Aneurysms that involve the aorta as it flows thru both the abdomen and chest are called thoracoabdominal aortic aneurysms.he aorta is the largest artery in the body and is the blood vessel that carries oxygen-rich blood away from the heart to all parts of the body. The section of the aorta that runs through the chest is called the thoracic aorta and, as the aorta moves down through the abdomen it is called the abdominal aorta.

Picture of the Aorta The aorta is divided into four sections: • The ascending aorta rises up from the heart and is about 2 inches long. The coronary arteries branch off the ascending aorta to supply the heart with blood. • The aortic arch curves over the heart, giving rise to branches that bring blood to the head, neck, and arms.

Ascending aorta At the union of the ascending aorta with the aortic arch the caliber of the vessel is increased, owing to a bulging of its right wall. This dilatation is termed the bulb of the aorta, and on transverse section presents a somewhat oval figure.etween each commissure of the aortic valve and opposite the cusps of the aortic valve, three small dilatations called the aortic sinuses. The sinotubular junction is the point in the ascending aorta where the aortic sinuses end and the aorta becomes a tubular structure.

Anatomy of the Heart: Aorta Branches of the Aorta. 1  Ascending Aorta - initial part of the aorta that begins from the aortic valve and extends from the left ventricle of the heart to the aortic arch. Coronary Arteries - arteries branching from the ascending aorta to supply oxygenated blood to the heart wall.

Ascending and Aortic Arch Aneurysms Ascending and Aortic Arch Aneurysms. An ascending aortic aneurysm is a bulge in the portion of the aorta closest to the heart. The ascending aorta begins at the heart's left ventricle and extends to the aortic arch, or the bend in the aorta. The arch of the aorta gives off branches to the head and arms.scending and Aortic Arch Aneurysm Treatment. Aneurysms in the ascending aorta and aortic arch usually require immediate surgery. UPMC's Center for Thoracic Aortic Disease offers a full range of state-of-the-art treatment strategies for aortic aneurysms.

Aortic Valve Disease Aortic valve stenosis is usually defined by restricted systolic opening of the valve leaflets, with a mean transvalvular pressure gradient of at least 10 mm Hg. The cause of the stenosis can be further defined based on the anatomy and disease process affecting the valve.

Types of Arches The four radii define the arch, starting from a small radius to switch from the left vertical to a large radius with its center in the right half of the opening to define the top portion of this arch. This is reflected on the opposite side of the arch.

Aortic Aneurysm - Topic Overview An aortic aneurysm (say a-OR-tik AN-yuh-rih-zum) is a bulge in a section of the aorta, the body's main artery. The aorta carries oxygen-rich blood from the heart to the rest of the body. Because the section with the aneurysm is overstretched and weak, it can burst.

Aortic arch The aortic arch, arch of the aorta or the transverse aortic arch is the part of the aorta between the ascending and descending aorta. The arch travels backward, so that it ultimately runs to the left of the trachea.

Aortic aneurysm Aortic aneurysms cause weakness in the wall of the aorta and increase the risk of aortic rupture. When rupture occurs, massive internal bleeding results, and, unless treated immediately, shock and death can occur.ortic aneurysms are classified by their location on the aorta. 1  An aortic root aneurysm, or aneurysm of the sinus of Valsalva. 2  Thoracic aortic aneurysms are found within the chest; these are further classified as ascending, aortic arch, or descending aneurysms.

Aortic Stenosis Aortic stenosis (AS) is a narrowing of the aortic valve in the heart. This valve is located between the left ventricle (lower pumping chamber) and the aorta. The aorta is the largest artery in the body. It transports blood from the heart throughout the body. The aortic valve has three cusps, or flaps, that control the direction and flow of the blood. Aortic stenosis causes obstruction or blockage of blood flow through this valve.

- arch definition. In architecture, a curved or pointed opening that spans a doorway, window, or other space. Note: The form of arch used in building often serves to distinguish styles of architecture from one another. For example, Romanesque architecture usually employs a round arch, and Gothic architecture, a pointed arch.

Aortic valve Aortic valve. The aortic valve is a valve in the human heart between the left ventricle and the aorta. It is one of the two semilunar valves of the heart, the other being the pulmonary valve. The heart has four valves and the other two are the mitral and the tricuspid valves. The aortic valve normally has three cusps or leaflets, although in 1–2% of the population it is found to congenitally have two leaflets.

Aortic arch The aortic arch is the portion of the main artery that bends between the ascending and descending aorta. It leaves the heart and ascends, then descends back to create the arch. The aorta distributes blood from the left ventricle of the heart to the rest of the body.

Arterial Supply Anatomy Ascending aorta. The ascending aorta commences at the upper part of the base of the left ventricle. At its origin, it presents (opposite the segments of the aortic valve) 3 small dilatations called the aortic sinuses. At the union of the ascending aorta with the aortic arch, the caliber of the vessel is increased.

- Arch of Aorta. The arch of the aorta is the second major anatomical region of the aorta; it curves above the heart between the ascending and descending aorta. All of the blood delivered from the heart to the systemic tissues of the body passes through the aorta, making it the largest artery in the human body.
