causes | |||
Supravalvulair (usually congenital) | |||
A pleat or membrane of the aorta | |||
Narrowing of the aorta | |||
Williams Syndrome | |||
valvular: | |||
Congenital form; often than bicuspid aortic valve | |||
Due to rheumatic fever | |||
degenerative form | |||
subvalvular: | |||
Congenital anomaly: a membrane in LVOT | |||
Hypertrophic obstructive cardiomyopathy, an autosomal dominant hereditary disorder | |||
Aortic subvalvular stenosis has also been described as a result of any of the lysosomal storage diseases | |||
Some patients have no symptoms, sudden, unexpected death, the first phenomenon. Fatigue, shortness of breath and lack of oxygen during exertion, chest pain and dizziness and fainting during exercise are further symptoms. The left ventricle must be at a higher pressure aortic valve stenosis in order to generate gain. Blood in the aorta Arises in the long run by left ventricular pressure load. Depending on the severity and cause of the problem, a valve replacement may be indicated. | Some patients have no symptoms, sudden, unexpected death, the first phenomenon.

Bicuspid aortic valve | |||
Risk of damage to the aortic valve | |||
rheumatic fever | |||
degeneracy | |||
endocarditis | |||
syphilis | |||
trauma | |||
Metabolic diseases, such as the mucopolysaccharidosen | |||
aortic dilation | |||
connective tissue disease, such as Marfan's syndrome, Ehlers-Danlos syndrome, | |||
aneurysm by inflammation, such as syphilis, vasculitis. | |||
aneurysm atherosclerotic lesions in aorta | |||
aortic dissection | |||
A serious aortic regurgitation caused a volume overload of the left ventricle. Since the blood that has been pumped out, it must be pumped out, once again touches the left ventricular overload and heart failure occurs. Patients complain of fatigue and shortness of breath. The valve, and possibly a part of the aortic arch, can be replaced. | A serious aortic regurgitation caused a volume overload of the left ventricle.
