Aortic Valve Stenosis



Aortic valve stenosis or aortic valve stenosis occurs when the aortic valve narrows. This stenosis prevents the valve from opening completely and prevents blood flow from your heart to the aorta and then to the rest of the body.

When the aortic valve is occluded, it is necessary to exercise the heart to move the body. After all, this extra work may limit the amount of pumpable blood and weaken your heart muscle.

For severe aortic stenosis, surgery is usually necessary to replace the valve. If left unconscious, stenosis of the aortic valve can cause serious problems of the heart.


Aortic valve stenosis ranges from mild to severe. The signs and symptoms of stenosis of the aortic valve generally develop when the stenosis of the valve is severe,

  • Chest pain (angina) or tension
  • I feel a slight feeling and exhaustion
  • Shortness of breath, in particular shortness of breath at the time of exertion
  • Fatigue, especially when activities become active
  • Heart heart palpitations – sudden beating heartbeat sensation
  • Cardiac murmur

The heart weakening effect of aortic valve stenosis may cause heart failure. Signs and symptoms of heart failure include fatigue, shortness of breath, and swollen ankles and feet.

Aortic valve stenosis does not immediately give warning signs and symptoms, it is difficult to detect at first. There is also a possibility that you do not recognize that symptoms are appearing. This condition is often found during routine physical examination when your doctor listens for abnormal heart sounds (mind murmur). This noise may occur long before other signs and symptoms develop.

Depending on the degree of stenosis, an infant or child with aortic valve stenosis has no symptoms and may have chest pain easily accompanied by tiredness or severe physical activity.

When going to see a doctor

Aortic valve stenosis usually affects adults, but can occur in children. Infants and children in that state may experience symptoms similar to adults. If you and your child have experienced such signs and symptoms, please consult your doctor.


Aortic valve stenosis is the stenosis of the aortic valve. Many things can narrow this passage between your heart and the aorta. For the cause of aortic valve stenosis,

Congenital heart failure.

The aortic valve consists of three tightly fitted triangular tissue flaps called cusps. Some children have only one aortic valve (single pointed), 2 (2 premolars) or 4 (4 peaked) cusps, not 3. This deformation may not cause problems until becoming an adult and the valve may narrow or leak, requiring repair or replacement.

Having inherently abnormal aortic valves requires periodic assessment by physicians to monitor the symptoms of valve problems. In most cases, the doctor does not know why the heart valve does not properly develop, so it can not be prevented.

Calcium accumulates in the valve.

With age, heart valves can accumulate calcium deposits (aortic valve calcification). Calcium is a mineral found in your blood. As blood flows repeatedly through the aortic valve, calcium deposits can accumulate at the valve cusps. These deposits never cause problems. These calcium deposits are not related to ingesting calcium tablets or drinking calcium-enriched beverages.

However, some people, especially those with congenital abnormal aortic valves, such as the congenital aortic valve, harden the valve cusps due to calcium deposits. This curing narrows the aortic valve and can occur at a younger age. However, stenosis of the aortic valve is associated with increased age and accumulation of calcium deposits in the aortic valve and is most common for males over 65 and over fifties.

Rheumatic fever.

Rheumatic fever, a complication of streptococcal infection, can form scar tissue in the aortic valve. There is a possibility of narrowing the aortic valve with scar tissue alone and causing aortic valve stenosis. Scar tissue also creates a rough surface where calcium deposits can gather and contributes to later aortic valve stenosis.

Rheumatic fever can damage multiple heart valves and can be damaged in multiple ways. A damaged cardiac valve can not be fully opened or completely closed. Rheumatic fever is rare in the United States, but older adults have rheumatic fever as children.

How does your mind work?

Your heart, the center of your circulation system consists of four rooms. Two upper chambers (atrium) receive blood. Two lower chambers (ventricles) send blood.

Blood coming back to your heart enters the right upper chamber (right atrium). From there, blood comes out in the right ventricle below. The right ventricle pumps blood into your lungs and blood is oxygenated.

Blood from your lungs will return to your heart, but this time you will return to the left ventricle (left atrium). Blood which is the main pump of your heart flows into the left ventricle. The left ventricle sends blood through the aortic valve every heartbeat to the aorta, the maximum artery of the body.

Your heart’s room has four heart valves. These valves open and close so that blood flows only in one direction through your heart.

  • Tricuspid valve
  • Pulmonic valve
  • Mitral valve
  • Aortic valve

The aortic valve – the entrance to the aorta of your heart – consists of three tight fitting triangular tissue cusps. These cusps connect to the aorta via a ring called a ring.

The heart valve opens like a one-way gate. The cusp of the aortic valve is forced to open when the left ventricle contracts and blood flows into the aorta. When all the blood in the left ventricle passes through the valve and the left ventricle relaxes, the cusps swirl to prevent blood that has just passed through the aorta from flowing back into the left ventricle.

A bad heart valve can neither fully open nor fail. If the valve does not close tightly, there is a possibility that blood will flow backward. This backflow through the valve is called reverse flow. When the valve narrows, the condition is called stenosis.

Risk Factors

Aortic valve stenosis is believed not to be preventable, and now it is not known why some people develop this condition. For some risk factors,

Deformed aortic valve.

Some people are born with the aortic valve stenosed or later develop aortic stenosis. Because the aortic valve was born with an aortic valve with two flaps (cusp). If you are born with one cusp (single cystic aortic valve) or four cusps (4 cusp aortic valve), you may develop aortic valve stenosis, which is a much rare condition.

The bicuspid aortic valve is a major risk factor for aortic valve stenosis. Bipedal aortic valves can move within families, so it is important to know family history. Bicuspid If you have relatives with the aortic valve, parents, brothers or children in the first rank, it is reasonable to check whether this abnormality exists.


Aortic valve stenosis may be associated with increased aging and accumulation of calcium deposits in heart valves.

Previous rheumatic fever.

Rheumatic fever may stiffen and fuse the flaps of the aortic valve and eventually cause aortic valve stenosis.

Chronic kidney disease.

Aortic valve stenosis is associated with chronic kidney disease.
Risk factors for aortic valve stenosis and atherosclerotic heart disease are similar, such as high blood pressure, high cholesterol, type 2 diabetes and smoking, and may indicate a relationship between them.


If the aortic valve is narrowing, the left ventricle has to send enough blood to the aorta and send it to the rest of the body.

In response to this, the left ventricle may thicken and expand. Initially, these indications help the left ventricle pump blood with more power. But ultimately, it is more difficult for the heart to maintain blood flow through a stenosed valve. After that, symptoms begin to appear. Ultimately, the extra work of the heart can weaken the left ventricle and your whole heart.

If left unchecked, stenosis of the aortic valve can lead to life-threatening heart problems including:

  • Chest pain (angina)
  • Fainting (syncope)
  • heart failure
  • Irregular heart rhythm (arrhythmia)
  • cardiac arrest
