Wha is a aortic stenosis?

Wha is a aortic stenosis?

Aortic stenosis...: Is narrowing or restriction of the aortic valve leaflets. When it occurs at old age it is usually senile calcific aortic stenosis and occurs on previously normal valves. Younger patients with stenosis tend to abnormal leaflets (2 vs 3). Mechanical stress may lead to valve thickening and fusion of the leaflets, which limits flow across the valve. With time, calcium may buildup on the valve as well. ...Read more

Aortic Stenosis (Definition)

The abnormal narrowing of the aortic valve. Progressive narrowing of the aortic valve means the heart must work harder to contract and "squeeze" the blood through a smaller and smaller outflow orifice. This will eventually cause symptoms such as chest pain, dyspnea, ...Read more

How is aortic stenosis treated?

Surgery vs Meds: Initially aortic stenosis (as) is treated with medications, but when the heart begins failing due to it as well as a few other parameters, it is time to think about surgical valve replacement. This can be done either as a traditional open heart operation or in some cases now percutaneously without having an incision. ...Read more

Aortic stenosis --is it serious?

Depends: Depends upon degree, other underlying disease and history of progression. It certainly can be serious, but with todays sophisticated echocardiography, we see a lot of mild aortic stenosis that is identified incidentally that will never amount to much. ...Read more

I : I am not exactly sure what your question is but would be happy to help if you could provide more information. You are likely referring to congenital aortic stenosis which is caused by abnormal formation of the valve leaflets of the aortic valve which is the last valve that blood passes through as it leaves the heart. A normal valve has 3 leaflets (tricuspid) but abnormal valves with only 2 leaflets (bicuspid, affecting up to 1% of the population) or 1 leaflet (unicuspid) are recognized. ...Read more

Blockage: It is a blockage of the valve leading from the heart. This can result in heart failure and a decrease in the ability of the heart to output blood to the rest of the body due to blockage in the aorta. ...Read more

What predisposes someone to aortic stenosis?

Aortic stenosis: Aortic stenosis is most commonly caused by age-related progressive calcification of a normal (three-leafed) aortic valve (>50% of cases). Other causes include calcification of a congenital bicuspid aortic valve (30-40% of cases) and acute rheumatic fever (less than 10% of cases). Diabetes, hypertension and hyperlipidemia may speed up the age-related calcification and degeneration of aortic valves. ...Read more

How does the condition aortic stenosis occur?

How does the condition aortic stenosis occur?

May start from birth: Aortic valve problems may start from birth if the aortic valve was abnormal due to a birth defect. As one ages, there can be progressive wear and tear of a bicuspid valve present since birth. There can also be wear and tear of a previously normal aortic valve in the elderly. Rheumatic fever can also cause scarring of the aortic valve in a child or adult. ...Read more

How do you diagnosevalvular aortic stenosis ?

Echo: An echocardiogram (often called "echo") is a graphic outline of the heart's movement. High-frequency sound waves, called ultrasound, provide pictures of the heart's valves and chambers. This allows the technician, to evaluate the pumping action of the heart. Echo is often combined with doppler ultrasound and color doppler to evaluate blood flow across the heart valves and provides the diagnosis. ...Read more

Could you tell me about aortic stenosis in children?

Could you tell me about aortic stenosis in children?

Valve disease: Classic aortic stenosis is obstruction to blood flow at the aortic valve. The aortic valve connects the heart (left ventricle) to the aorta, which carries blood to the body. A normal aortic valve has three separate leaflets. In typical aortic stenosis in children, there is partial or complete fusion between at least two of the leaflets of the valve, which restricts opening of the valve. ...Read more

How will aortic stenosis affect other parts of my body?

How will aortic stenosis affect other parts of my body?

It will vary: Aortic stenosis means that the valve that allows blood to go from your heart to the rest of your body is narrowed. How this affects the rest of your body will depend on how narrow it is; if it's severely narrowed it affect blood supply to the rest of the body and coronaries but more importantly it will make your heart work very hard to pump blood out and this may produce long term damage. ...Read more

What is the definition or description of: Aortic stenosis?

Aortic Stenosis: Aortic stenosis is the abnormal narrowing of the aortic valve. As the aortic valve develops progressive narrowing, the heart must work harder to contract and "squeeze" the blood through a smaller and smaller outflow orifice. This will eventually cause symptoms such as chest pain, dyspnea, or loss of consciousness. Severe aortic stenosis requires valve replacement. ...Read more

Can you tell me how is a diagnosis of aortic stenosis made?

Echocardiogram: Physical exam can be helpful, but echocardiography (cardiac ultrasound) is generally the diagnostic study of choice. Using echo, you can examine the morphology and movement of the valve leaflets, and measuring blood flow velocities, you can estimate pressure gradients to assess severity of obstruction. Cath can sometimes be helpful in assessment and may allow intervention in some cases. ...Read more
