Aortic valve malady is a gradually dynamic issue with a diseasecontinuum that ranges from mellow valve thickening without obstacle of blood stream, termed aortic sclerosis, to serious calcification with debilitated handout movement, oraortic stenosis.Histopathologic investigations of aortic sclerosis show central subendothelial plaquelike sores on the aortic side of the handout that stretch out to the nearby fibrosa layer.
The three principal symptoms of aortic stenosis are chest pain with exertion, shortness of breath with exertion due to failure of the left ventricle, and sudden loss of consciousness; weakness, fatigue and heart palpitations may also be present. Blood pressure usually is normal and the heart rhythm regular. In advanced cases, there may be an abnormally low systolic pressure as compared to the diastolic pressure.
Statistics: The prevalence in the Argentina of any valve disease is 1.5%. Of those with valve disease about 0.4% have aortic stenosis. The prevalence of moderate or severe aortic stenosis in patients more than 75 years old is 1.8%. It is the most common valvular heart disease of the elderly and increases with age. The prevalence is 0.5% at age 75 years and 6.1% at 85 years
