Coarctation
|
|
CoarctationA narrowing, a stricture, a constriction. Although the best known coarctation is of the aorta, any artery can have a coarctation. The word "coarctation" comes from the Latin "coartare" meaning :to press together." The sides of the vessel at the point of a coarctation appear pressed together.
RELATED TERMS--------------------------------------
Stricture
The abnormal narrowing of a body opening. Also called stenosis. See also esophageal stricture and pyloric stenosis.
Coarctation
A narrowing, a stricture, a constriction. Although the best known coarctation is of the aorta, any artery can have a coarctation. The word "coarctation" comes from the Latin "coartare" meaning :to press together." The sides of the vessel at the point of a coarctation appear pressed together.
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--------------------------------------
Coarctation of the Aorta
A severe narrowing of the aorta, causing a decrease in blood flow to the lower part of the body. This narrowing is a congenital defect and can be corrected with surgery.
Coarctation of the aorta
A 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.
Coartem
A medicine used in the treatment of malaria, based in artemether and lumefantrine.
PREVIOUS AND NEXT TERMS--------------------------------------
Co-morbid
Pertaining to two or more disorders simultaneously.
Co-payment
A payment made by an individual who has health insurance, usually at the time a service is received, to offset some of the cost of care. Co-payments are a common feature of HMO (Health Maintenance Organization) and PPO (Preferred Provider Organization) health plans in the US. Co-payment size may vary depending on the service, generally with low copayments required for visits to a regular medical provider and higher payments for services received in the emergency room, the latter intended to discourage insured persons from using the emergency room unless it is absolutely necessary. Also called co-insurance.
Co-stimulation
An event in the immune system involving the delivery of a second signal by an antigen-presenting cell. The second signal rescues the activated T cell from anergy (which is a state of immune unresponsiveness), allowing the T cell to produce the lymphokines necessary for the growth of additional T cells.
Coagulation
In medicine, the clotting of blood. The process by which the blood clots to form solid masses, or clots.
Coagulation, laser
The coagulation (clotting) of tissue using a laser. A coagulation laser produces light in the visible green wavelength that is selectively absorbed by hemoglobin, the pigment in red blood cells, in order to seal off bleeding blood vessels.
Coarctation
Coarctation of the aorta
A 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.
Coated stent
Also known as a medicated stent. A tiny cage coated with a drug to prop open an artery and prevent it from closing again.
Cocci
Bacteria which are spherically shaped.
Coccidioidomycosis (CM)
A disease due to a fungus called Coccidioides immitis. About 40% of people infected with this fungus develop symptoms. Most often they have an influenza-like illness with fever, cough, headaches, rash, and myalgias (muscle pains). Of those people with symptoms, 8% have severe lung disease requiring hospitalization and 7% develop disseminated infection (throughout the body).
Coccus
A bacterial cell which has the shape of a sphere. Coccus enters into the name of a number of bacteria. For example, enterococcus, meningococcus, pneumococcus, staphylococcus, and streptococcus.
