Ascending Aorta Replacement
|
|
Ascending Aorta ReplacementThe aorta is the main blood vessel that leaves the heart to provide blood flow to the rest of the body. When the ascending or first part of the aorta is diseased, it sometimes needs to be replaced. The replacement is most often done with a synthetic cloth tube.
RELATED TERMS--------------------------------------
Aorta
The largest artery in the body and the primary blood vessel leading from the heart to the body.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
Heart
The hollow, muscular organ responsible for pumping blood through the circulatory system.
SIMILAR TERMS--------------------------------------
Ascending aorta
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. The right and left coronary arteries that supply blood to the heart muscle arise from the ascending aorta. The ascending aorta is an arbitrary anatomic entity. The aorta is one continuous conduit that stems from the left ventricle of the heart to carry blood to most of the body. The ascending aorta is, however, a hallowed and convenient division of the aorta.
Ascending colon
The part of the colon on the right side of the abdomen.
Ascending pathway
A nerve pathway that goes upward from the spinal cord toward the brain carrying sensory information from the body to the brain. In contrast, descending pathways are nerve pathways that go down the spinal cord and allow the brain to control movement of the body below the head.
Ascensia
A blood glucose monitoring system by Bayer.
PREVIOUS AND NEXT TERMS--------------------------------------
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.
Arterial Grafting
In patients who require coronary artery bypass graft surgery, it is sometimes desirable to use arteries from other parts of the body to provide the bypass grafts. This is known as arterial grafting. The alternative is to use vein grafts for coronary bypass surgery.
Arteries
Blood vessels that carry blood away from the heart to the arms, legs, head, body and organs.
Arteriosclerosis ("hardening of the arteries")
The process whereby abnormal deposits of lipids, cholesterol and plaque build up, leading to narrowing or blockage in arteries taking blood to the hand, foot head or vital organs. Also called atherosclerosis.
Ascending Aorta Replacement
Atherectomy (Directional Coronary Atherectomy or DCA)
The DCA catheter has a hollow cylinder on the tip with an open window on one side and a balloon on the other. When the catheter is inserted into the narrowed artery, the balloon is inflated, pushing the window against the fatty matter clogging the vessel. A blade (cutter) within the cylinder rotates and shaves off any fat, which protruded into the window. The shavings are caught in a chamber within the catheter and removed. This process is repeated as needed to allow better blood flow.
Atheroma:
Large build-up of fat, cholesterol and other substances on the walls of an artery, causing narrowing. Also called plaque.
Atrial fibrillation (AF)
Atrial fibrillation is an irregular heart rhythm in which many impulses begin and spread through the atria. The resulting rhythm is disorganized, rapid and irregular and the atria are not able to fully empty their contents into the ventricles.
Atrial Myxoma
A myxoma is a tumor of the heart. It resides in the atrial chamber and causes symptoms when its growth produces a tumor so large it obstructs blood flow through the heart chambers.
