Aortic stenosis is most commonly caused by calcium buildup on the aortic valve over time. These calcium deposits that often come with age make the valve tissue stiff, narrow, and unyielding.

Symptoms

  • Shortness of breath
  • Chest pain, pressure, or tightness
  • Fatigue
  • Feeling lightheaded or dizzy
  • Difficulty when exercising or completing day-to-day activities

Causes

Aortic stenosis (AS) is one of the most common and serious valve disease problems. The heart pumps blood through the aortic valve to the body. Over time, calcium buildup can narrow the valve opening and restrict blood flow to the heart. If left undiagnosed or untreated in a timely fashion, it can become more severe and can ultimately lead to ...

Prevention

Who is at risk of Aortic Stenosis? Aortic stenosis mainly affects older people, and onset starts at around 60, but is more likely to develop in the 70s or the 80s. Children with congenital heart defects can develop aortic stenosis when only two cusps grow, instead of the normal three. This is a bicuspid aortic valve.

Complications

When people do experience symptoms of aortic stenosis, they can include:

  • Shortness of breath
  • Dizziness or fainting
  • Fatigue or reduced ability to do activities requiring mild exertion
  • Chest pain, pressure or tightness
  • Palpitations or a feeling of heavy, pounding, or noticeable heartbeats

What is the main cause of aortic stenosis as in older patients?

In most elderly adults, aortic stenosis is caused by a build-up of calcium (a mineral found in your blood) on the valve leaflets. Over time, this causes the leaflets to become stiff, reducing their ability to fully open and close.

What is the most common type of aortic stenosis?

The most common cause of aortic stenosis in young people is a birth defect where only two cusps grow instead of the normal three. This is called a “bicuspid aortic valve.” Another cause may be that the valve opening doesn't grow along with the heart.

How long can you live with mild aortic stenosis?

Without treatment, a person's life expectancy with aortic stenosis after symptoms develop is 1–3 years. Around 50–68% of symptomatic people die within 2 years. Often, they die suddenly. However, aortic valve replacement surgery significantly increases life expectancy.

What increases aortic stenosis?

Causes include a congenital bicuspid valve, idiopathic degenerative sclerosis with calcification, and rheumatic fever. Untreated AS progresses to become symptomatic with one or more of the classic triad of syncope, angina, and exertional dyspnea; heart failure and arrhythmias may develop.

What are the three major symptoms of aortic stenosis?

Signs and symptoms of aortic valve stenosis may include:Abnormal heart sound (heart murmur) heard through a stethoscope.Chest pain (angina) or tightness with activity.Feeling faint or dizzy or fainting with activity.Shortness of breath, especially when you have been active.More items...•

Who is at risk for aortic stenosis?

Particularly, the aortic valve sclerosis (aortic valve thickening and calcification without pressure gradient) seem to affect about one fourth of adults over 65 years of age, while the aortic valve stenosis is present in 2–9% of general population over 65 years of age; an increased prevalence of both sclerosis and ...

Does vitamin D cause aortic stenosis?

Conclusions: Vitamin D and or Calcium supplement intake worsens aortic stenosis progression and increases the need for AVR. It does not have a significant impact on mortality.

What medications should be avoided with aortic stenosis?

Antihypertensive treatment with β-blockers has generally been avoided in patients with severe aortic stenosis (AS) due to the concerns for inducing left ventricular dysfunction and hemodynamic compromise in the presence of severe outflow tract obstruction.

What are signs that aortic stenosis getting worse?

Call your doctor about new or worsening symptoms, including:Chest pain or tightness.Rapid fluttering heartbeat.Shortness of breath.Dizziness or faintness.Increased exhaustion after activity.Swollen ankles and feet.Difficulty sleeping.

Can you reverse aortic stenosis?

TAVR: Newer, Less Invasive Treatment for Aortic Stenosis However, there are no medications that can reverse aortic stenosis. The only cure is replacing the diseased valve. Usually, heart valve replacement requires open-heart surgery.

How long does it take for aortic stenosis to progress?

According to The Cleveland Clinic, catheterization and echocardiographic studies suggest that, on average, the valve area declines 0.1-0.3 square centimeters per year. The Cleveland Clinic also states that the systolic pressure gradient across the aortic valve can increase by as much as 10-15 mm Hg per year.

How do you slow down aortic stenosis?

Statins and ACE-Inhibitors have been identified as the two most promising candidates. Both statins and ACE-Inhibitors have been shown to reduce the progression of atherosclerotic disease and to significantly improve the clinical outcome among patients with coronary artery disease.

Causes of Aortic Stenosis

We do not know why some people’s aortic valves fail to form properly before birth, though genetics or environmental exposure may play a role. When the valve narrows after birth, it is because of:

Treatment for Aortic Stenosis

Our team approach brings together the expertise of Stanford surgeons and interventional cardiologists to determine the best care plan for you. Instead of sharing files electronically, our doctors and imaging specialists take the time to meet face-to-face to discuss your results and make sure they pinpoint the problem.

When does aortic stenosis start?

Aortic stenosis mainly affects older people as a result of scarring and calcium buildup in the valve cusp (flap or fold). Age-related AS usually begins after age 60, but often doesn’t show symptoms until ages 70 or 80.

How to tell if a child has aortic stenosis?

Infants and children who have aortic stenosis due to a congenital defect may exhibit symptoms such as: 1 Fatigue upon exertion 2 Failure to gain weight 3 Poor or inadequate feeding 4 Breathing problems

What to do if you have no symptoms of aortic stenosis?

If there are no symptoms or if symptoms are mild, the best course of action could be regular follow up and monitoring to see if any symptoms develop or worsen. However, anyone with aortic stenosis should be checked with an echocardiogram to determine treatment options.

How do you know if you have aortic stenosis?

Symptoms of aortic stenosis may include: Chest pain. Rapid, fluttering heartbeat. Trouble breathing or feeling short of breath.

What is the most common valve disease?

Aortic stenosis is one of the most common and serious valve disease problems. Aortic stenosis is a narrowing of the aortic valve opening. Aortic stenosis restricts the blood flow from the left ventricle to the aorta and may also affect the pressure in the left atrium.

Why is my aortic valve narrow?

This makes the heart work harder to pump blood to the restricted opening. Over the years the defective valve often becomes stiff and narrow because of calcium build-up.

What happens if you have a thickened heart wall?

This may lead to heart failure. Appropriate treatment can help reverse or slow down the progress of this disease.

Causes

Aortic stenosis is the most common form of valve disease, occurring more often in men than women. For most people, the condition develops with age. More than 2.5 million people over the age of 75 in the United States have aortic stenosis.

Symptoms

In the mild to moderate stages of aortic stenosis, blood flow usually isn't restricted enough to cause symptoms. Many people don't know they have the condition at this stage. Some patients are told that they have a heart murmur during a routine checkup.

What are the symptoms of aortic stenosis?

Common symptoms may include: breathlessness with activity. chest discomfort. fainting, weakness or dizziness with activity. inability to perform activities that were once easy.

What is the condition where the aortic valve narrows?

Aortic stenosis is a condition characterized by narrowing of the aortic valve, resulting in restriction of blood flow out of the heart.

What is the name of the valve that separates the left ventricle and the aorta?

The aortic valve is a one-way valve that separates the left ventricle (heart chamber that pumps oxygen-rich blood to the body) from the aorta (the main blood vessel of the body). When the left ventricle squeezes, the aortic valve opens and allows blood to flow from the heart to the body. Aortic stenosis is a condition characterized by narrowing ...

What causes aortic stenosis in young people?

The most common cause of aortic stenosis in young people is a birth defect where only two cusps grow instead of the normal three. This is called a “bicuspid aortic valve.”

When does aortic stenosis start?

Aortic stenosis mainly affects older people as a result of scarring and calcium buildup in the valve cusp (flap or fold). Age-related AS usually begins after age 60, but often doesn’t show symptoms until ages 70 or 80.

What is the aortic stenosis?

Aortic stenosis ( AS or AoS) is the narrowing of the exit of the left ventricle of the heart (where the aorta begins), such that problems result. It may occur at the aortic valve as well as above and below this level. It typically gets worse over time. Symptoms often come on gradually with a decreased ability to exercise often occurring first.

How many people have aortic valve stenosis?

Approximately 2% of people over the age of 65, 3% of people over age 75, and 4% percent of people over age 85 have aortic valve stenosis. The prevalence is increasing with the aging population in North America and Europe.

What is the risk of death from aortic valve stenosis?

Syncope (fainting spells) from aortic valve stenosis is usually exertional. In the setting of heart failure it increases the risk of death. In people with syncope, the three-year mortality rate is 50% if the aortic valve is not replaced.

Why does my left ventricle make a loud noise?

This is a result of the increasing calcification of the valve preventing it from "snapping" shut and producing a sharp, loud sound. Due to increases in left ventricular pressure from the stenotic aortic valve, over time the ventricle may hypertrophy, resulting in diastolic dysfunction.

Why does my heart make a fourth sound?

As a result, there may be a fourth heart sound due to the stiff ventricle. With continued increases in ventricular pressure, dilatation of the ventricle will occur, and a third heart sound may be manifest. Finally, aortic stenosis often co-exists with some degree of aortic insufficiency ( aortic regurgitation ).

Why does my aortic valve harden?

A bicuspid aortic valve affects about one to two percent of the population. As of 2014 rheumatic heart disease mostly occurs in the developing world.

What is the term for a heart valve that narrows without narrowing?

Thickening of the valve without narrowing is known as aortic sclerosis.
