Aortic

   Pertaining to the aorta, the largest artery in the body.

RELATED TERMS
--------------------------------------

Aorta
The largest artery in the body and the primary blood vessel leading from the heart to the body.

Artery
A blood vessel that carries blood from the heart to the body.



SIMILAR TERMS
--------------------------------------

Aorta
The largest artery in the body and the primary blood vessel leading from the heart to the body.

Aorta, abdominal
The abdominal aorta is the final section of the aorta, the largest artery in the body. It is a continuation of the thoracic aorta. It begins at the diaphragm, and runs down to the point where it ends (by splitting in two to form the common iliac arteries).

Aorta, ascending
The ascending aorta is the first section of the aorta, the largest artery in the body. The ascending aorta starts from the left ventricle of the heart and extends to the arch (the bend) of the aorta.

Aorta, coarctation of the
" congenital constriction of the aorta, impeding the flow of blood below the level of the constriction and increasing blood pressure above the constriction. Symptoms may not be evident at birth but may develop as soon as the first week after birth with congestive heart failure or high blood pressure that call for early surgery. The surgery otherwise can be delayed. The outlook after surgery is favorable. Some cases have been treated by balloon angioplasty. The word ""coarctation"" comes from the Latin ""coartare"" meaning :to press together."" The sides of the aorta at the point of a coarctation appear pressed together."

Aorta, descending
The descending aorta is the part of the aorta, the largest artery in the body, that runs down through the chest and the abdomen. The descending aorta starts after the arch of the aorta and ends by splitting into two great arteries (the common iliac arteries) that go to the legs.

Aorta, thoracic
The thoracic aorta is a section of the aorta, the largest artery in the body, within the chest. Specifically, the thoracic aorta is that part of the aorta that starts after the arch of the aorta and runs down to the diaphragm, the great muscle that separates the chest from the abdomen.

Aortal
Pertaining to the aorta, the largest artery in the body. The preferred term is aortic.

Aortic aneurysm
"An outpouching (a local widening) of the largest artery in the body, the aorta, involving that vessel in its course above the diaphragm (thoracic aortic aneurysm) or, more commonly, below the diaphragm (abdominal aortic aneurysm). The diagnosis of an aortic aneurysm can be straight forward or difficult. Around 1900 the eminent physician William Osler said: ""There is no disease more conducive to clinical humility than aneurysm of the aorta."" At the area of the aneurysm, there is typically a bulge and the wall is weakened and may rupture. Because of the volume of blood flowing under relatively high pressure through the aorta, a ruptured aneurysm of the aorta is a catastrophe."

Aortic arch
The second section of the aorta. The aorta first ascends, then bends, and then descends. The bend is the aortic arch. It gives off the brachiocephalic trunk, the left common carotid artery, and the left subclavian artery. The brachiocephalic trunk, the first branch off the aortic arch, splits to form the right subclavian artery and the right common carotid artery which supply blood, respectively, to the right arm and to the right side of the neck and head. The left common carotid artery and left subclavian artery, the second and third branches off the aortic arch, perform parallel functions on the left side.

Aortic Arch Replacement
The aortic arch is that segment of the aorta between the ascending and descending portions. The aortic arch provides the origin for the blood vessels to the upper part of the body, specifically the arms and head. Surgical diseases of the aortic arch can require a replacement of this large blood vessel with preservation of the vessels to the upper body. The most common diseases requiring replacement are an aneurysm of the aortic arch or an aortic dissection involving the aortic arch.

Aortic arch syndrome
1. Any disorder that causes occlusion of the arteries that arise from the aortic arch. 2. Synonym for Takayasu disease. 3. The subclavian steal syndrome.

Aortic atresia
Congenital absence of the normal valvular opening from the left ventricle of the heart into the aorta. Atresia here refers to the absence of a normal opening.

Aortic dissection
A progressive tear in the aorta. The inner lining (intima) of the aorta tears and blood surges through the tear, creating a new false channel and separating (dissecting) the middle layer (media) from the outer layer of the aorta.

Aortic insufficiency
Incomplete closure of the aortic valve resulting in aortic regurgitation, the return of blood from the aorta into the left ventricle of the heart.

Aortic Insufficiency
Aortic insufficiency refers specifically to the aortic valve, which is the valve the blood passes through as it leaves the heart and enters the aorta. When blood leaks back through the valve it is known as aortic insufficiency. Small amounts of aortic insufficiency may be inconsequential, but larger amounts require repair or replacement of the aortic valve.

Aortic regurgitation
The return of blood from the aorta into the left ventricle of the heart due to aortic insufficiency, incomplete closure of the aortic valve.

Aortic stenosis
Narrowing (stenosis) of the heart valve between the left ventricle of the heart and the aorta. This narrowing impedes the delivery of blood through the aorta to the body and makes it tough for the heart to carry out this Herculean task. A normal aortic valve has three leaflets or cusps, but a stenotic valve may have only one cusp (unicuspid) or two cusps (bicuspid), which are thick. stiff and stenotic. Some children with aortic stenosis have chest pain, unusual fatigue, dizziness or fainting. Many children have few or no symptoms. The need for surgery depends on the degree of stenosis. Although surgery may enlarge the stenotic valve the valve remains deformed and eventually may need to be replaced with an artificial one. A procedure called balloon valvuloplasty has been used in some children with aortic stenosis. Persons with aortic stenosis need medical follow-up all their lives since even mild stenosis may worsen over time and need treatment.

Aortic valve
The valve that regulates blood flow from the heart into the aorta.

Aortic Valve
The aortic valve is the last valve through which the blood passes before it enters the aorta or main blood vessel of the body. The valve prevents blood from leaking back into the left ventricle from the aorta after it has been ejected from the heart.

Aortic Valve Homograft
When replacement of an aortic valve is necessary it is possible to replace the valve with another human valve known as an aortic valve homograft. This operation involves cardiopulmonary bypass

Aortic Valve Repair
The aortic valve is the last valve in the heart through which the blood travels prior to circulating in the body. When this valve is leaking or too tight, the surgeon may be able to repair the valve rather than replace it.

Aortic Valve Replacement
When the aortic valve is diseased, it can become either stenotic (too narrow) or insufficient (leaky). In such cases, the aortic valve may need to be replaced with either a prosthetic or human valve.

Aortic valve, bicuspid
Whereas the normal aortic valve in the heart has three flaps (cusps) that open and close, a bicuspid valve has only two. There may be no symptoms in childhood, but in time the valve may become stenotic (narrowed), making it harder for blood to pass through it, or the valve may start to let blood leak backwards through the valve (regurgitate). Treatment depends on how the valve is working and overall condition of the affected individual.

Aortitis
Inflammation of the aorta. The causes of aortitis include syphilis or rheumatic fever.
