. . Aortic stenosis makes infective endocarditis, a severe infection of the heart lining and valves, more likely. It's caused by bacteria getting into your bloodstream -- even through your gums. To. . Aortic sclerosis is associated with systemic endothelial dysfunction, and a small percentage of cases may progress to aortic stenosis. Lowering of LDL cholesterol by 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors have been shown to decrease progression of aortic valve calcification. Aortic sclerosis is not a mere benign. . Calcific aortic valve disease is a slowly progressive disease that starts with mild fibrosis and calcification and thickening of the valve leaflets without obstruction of blood flow, which is termed aortic sclerosis [].This disease evolves over the years to severe calcification with impaired leaflet mobility and significant obstruction to blood flow, i.e. aortic stenosis (AS). Calcific aortic stenosis is the most common indication for surgical valve replacement in the United States. 1 With the decline of acute rheumatic fever, calcific aortic stenosis has become the most common indication for valvular disease in the United States. Landmark epidemiological studies identified risk factors for the aortic valve which are similar to those of vascular atherosclerosis.

. . ing and calcification of aortic valve leaflets, i.e., aortic valve sclerosis, which leads to reduction of valve opening and obstruction to left ventric- ular (LV) outflow [3]. Surgery for Asymptomatic Aortic Valve Stenosis * Surgery is not traditionally considered for the asymptomatic patient, regardless the degree of stenosis, because the risk of sudden death is considered to be low (estimated at<1%/year), and the risk of the AVR may exceed the potential benefit of surgery.; Severe AS need to be followed carefully for the development of symptoms or rapidly. . . A doctor may suspect aortic valve sclerosis on hearing a heart murmur with a stethoscope. However, an ultrasound of the heart (echocardiogram) can distinguish between aortic valve sclerosis and stenosis and check for other possible causes of a heart murmur. Calcified valve leaflets can also impact each of the other valves within the heart - the. .

The prevalence of aortic stenosis in the population older than 65 years is 2% to 7%; aortic sclerosis, the precursor to aortic stenosis in which there is valve thickening but no stenosis, is present in approximately 25% of this age group. 2, 3 Whereas aortic stenosis is seen in patients with both tricuspid and bicuspid aortic valves, the. If a valve doesn't fully open or close, blood flow is reduced or blocked. In aortic valve stenosis, the aortic valve between the lower left heart chamber (left ventricle) and the aorta does not open completely. The area through which blood moves out of the heart to the aorta is narrowed (stenosis). . . Aortic sclerosis is a degenerative aortic valve disease with thickening of aortic valve structures by fibrosis and calcification initially without causing significant obstruction. Over years, aortic sclerosis progresses to stenosis in as many as 15% of patients. . . .
