Aortic valve disorder is a condition in which the valve between the heart and the aorta, the primary artery in the body, does not work properly, according to Mayo Clinic. The condition includes several different types of diseases, including aortic valve stenosis and aortic valve regurgitation.
Aortic valve regurgitation is a condition in which the valve doesn't close properly, causing blood to flow back into the heart's left ventricle, Mayo Clinic explains. The left ventricle is the heart's primary pumping chamber. Aortic valve stenosis is caused by a narrowing of the aorta that leads to the valve not opening properly. It can limit the amount of blood being pumped to the rest of the body.
Aortic valve stenosis is the most common form of aortic valve disorder to require surgery, according to University of Maryland Medical Center. The most frequent cause of the condition is degeneration of the aortic valve due to aging.
Symptoms of aortic stenosis including fainting, shortness of breath and chest pain, as noted by University of Maryland Medical Center. Many patients with the condition have no symptoms at all, but once a patient becomes symptomatic, surgery is usually required. Surgery typically improves both circulation and heart function.
