Causes & Risk Factors

Several factors can contribute to Aortic Stenosis.

The most common cause of aortic stenosis in older adults is the gradual buildup of calcium deposits on the valve leaflets, much like how mineral deposits can clog old water pipes.

The most common cause of aortic stenosis in older adults is the gradual buildup of calcium deposits on the valve leaflets, much like how mineral deposits can clog old water pipes. This process, called calcific aortic stenosis, happens naturally with aging as calcium accumulates over decades of normal wear and tear. The valve leaflets become thick and rigid, unable to open fully during each heartbeat.

Some people are born with a bicuspid aortic valve, meaning they have only two leaflets instead of the normal three.

Some people are born with a bicuspid aortic valve, meaning they have only two leaflets instead of the normal three. This congenital condition affects about 1-2% of the population and puts extra stress on the valve throughout life, often leading to stenosis in the 40s or 50s rather than later in life. The abnormal structure causes uneven blood flow that accelerates wear and damage.

Rheumatic heart disease, once a leading cause of aortic stenosis, occurs when childhood strep throat infections aren't properly treated and lead to rheumatic fever.

Rheumatic heart disease, once a leading cause of aortic stenosis, occurs when childhood strep throat infections aren't properly treated and lead to rheumatic fever. The body's immune response damages the heart valves, causing them to scar and narrow over time. While less common today due to better antibiotic treatment, this remains a significant cause in some parts of the world.

Risk Factors

Age over 65 years
Being male
Born with a bicuspid aortic valve
History of rheumatic fever in childhood
High blood pressure
High cholesterol levels
Diabetes
Chronic kidney disease
Smoking cigarettes
Family history of aortic valve disease

Diagnosis

How healthcare professionals diagnose Aortic Stenosis:

1
When you visit your doctor with symptoms that might suggest aortic stenosis, they'll start by listening to your heart with a stethoscope.
When you visit your doctor with symptoms that might suggest aortic stenosis, they'll start by listening to your heart with a stethoscope. Aortic stenosis creates a distinctive heart murmur - a harsh, rasping sound that occurs when blood flows through the narrowed valve. Your doctor can often detect this murmur during a routine physical exam, even before symptoms develop.
2
The gold standard test for diagnosing aortic stenosis is an echocardiogram, a painless ultrasound of your heart that creates detailed images of your valve in action.
The gold standard test for diagnosing aortic stenosis is an echocardiogram, a painless ultrasound of your heart that creates detailed images of your valve in action. This test shows how well your valve opens and closes, measures the degree of narrowing, and evaluates how your heart muscle is responding to the extra workload. The test typically takes 30-60 minutes and involves applying gel to your chest while a technician moves a wand-like device to capture images.

Your doctor might order additional tests to get a complete picture of your condi
Your doctor might order additional tests to get a complete picture of your condition: - Electrocardiogram (EKG) to check your heart's electrical activity - Chest X-ray to see your heart size and look for fluid in your lungs - Cardiac catheterization to evaluate your coronary arteries if surgery is being considered - CT scan of your heart to get detailed images of your valve structure - Stress test to see how your heart responds to physical activity

Complications

The most serious complication of untreated severe aortic stenosis is heart failure, which develops when your heart muscle becomes too weak or stiff to pump blood effectively.
This happens because your heart works overtime for years trying to push blood through the narrowed valve.
Heart failure can cause severe shortness of breath, swelling, and fatigue that significantly impacts your quality of life.
Other potentially serious complications include dangerous heart rhythm abnormalities, sudden cardiac death (though rare), and stroke from blood clots.
The risk of these complications increases significantly once symptoms develop, which is why doctors typically recommend valve replacement soon after symptoms begin.
Fortunately, successful valve replacement can reverse most of these complications and restore normal heart function in the majority of patients.

Prevention

Keep your blood pressure well-controlled through medication, diet, and exercise
Maintain healthy cholesterol levels with lifestyle changes and medications if needed
Don't smoke, and quit if you currently smoke
Exercise regularly within your doctor's recommendations
Eat a heart-healthy diet rich in fruits, vegetables, and whole grains while limiting saturated fats
Manage diabetes carefully if you have it

Treatment Approaches

Treatment for aortic stenosis depends on the severity of your condition and your symptoms.

Treatment for aortic stenosis depends on the severity of your condition and your symptoms. If you have mild stenosis without symptoms, your doctor will typically recommend regular monitoring with echocardiograms every 1-2 years to track progression. During this watchful waiting period, managing other heart disease risk factors like high blood pressure and cholesterol becomes especially important.

Once aortic stenosis becomes severe or symptoms develop, valve replacement becomes necessary.

Once aortic stenosis becomes severe or symptoms develop, valve replacement becomes necessary. Surgical aortic valve replacement (SAVR) is the traditional approach, where a cardiac surgeon removes your diseased valve and replaces it with either a mechanical valve or a biological valve made from cow or pig tissue. This open-heart surgery has excellent long-term results and is often the best choice for younger, healthier patients.

SurgicalImmunotherapy

For patients who are older or have other health conditions that make surgery risky, transcatheter aortic valve replacement (TAVR) offers a less invasive alternative.

For patients who are older or have other health conditions that make surgery risky, transcatheter aortic valve replacement (TAVR) offers a less invasive alternative. During TAVR, doctors insert a new valve through a catheter, usually through a small incision in your groin. The new valve is positioned inside your old valve and immediately begins working. This procedure typically requires only 1-2 days in the hospital compared to 5-7 days for open surgery.

Surgical

While medications can't cure aortic stenosis, they help manage symptoms and related conditions: - Blood pressure medications to reduce strain on your heart - Diuretics to help remove excess fluid if you develop heart failure - Medications to control irregular heart rhythms - Statins to manage cholesterol levels However, certain heart medications like ACE inhibitors must be used carefully in severe aortic stenosis, as they can sometimes worsen symptoms.

Living With Aortic Stenosis

Living successfully with aortic stenosis requires partnering closely with your healthcare team and staying alert to changes in your symptoms. Keep a simple log of your energy levels and any new symptoms like increased shortness of breath or chest discomfort. Many people find it helpful to use a smartphone app or journal to track these changes, as gradual symptom progression can be easy to overlook day-to-day.

Lifestyle adjustments can help you maintain your quality of life while managing Lifestyle adjustments can help you maintain your quality of life while managing the condition: - Pace yourself during physical activities and rest when you feel tired - Avoid sudden, strenuous activities that might cause dangerous drops in blood pressure - Stay up-to-date with dental care and inform your dentist about your valve condition - Take prescribed antibiotics before dental procedures if your doctor recommends them - Maintain a heart-healthy diet and stay well-hydrated - Get annual flu shots and stay current with other vaccinations

The emotional aspect of living with aortic stenosis is equally important to address.The emotional aspect of living with aortic stenosis is equally important to address. Many people experience anxiety about their diagnosis or worry about needing surgery. Consider joining a support group for people with heart valve disease, either in person or online. Remember that modern treatments for aortic stenosis are highly successful, and most people return to normal or near-normal activity levels after valve replacement. Stay connected with family and friends, and don't hesitate to ask for help when you need it.

Frequently Asked Questions

Can I still exercise if I have aortic stenosis?

The answer depends on how severe your stenosis is and whether you have symptoms. People with mild stenosis can usually continue most normal activities, while those with severe stenosis should avoid strenuous exercise. Your cardiologist can provide specific guidelines based on your individual situation and may recommend an exercise stress test to determine safe activity levels.

How quickly does aortic stenosis get worse?

Aortic stenosis typically progresses slowly over many years. On average, the valve area decreases by about 0.1 square centimeters per year, but this varies significantly between individuals. Some people remain stable for years, while others progress more rapidly, especially those with bicuspid valves or other risk factors.

Will I need to take blood thinners after valve replacement?

This depends on the type of valve you receive. Mechanical valves require lifelong blood thinner medication to prevent clots, while biological valves typically only need blood thinners for 3-6 months after surgery. Your surgeon will discuss the pros and cons of each type based on your age, lifestyle, and other health factors.

Can aortic stenosis cause a heart attack?

Aortic stenosis doesn't directly cause heart attacks, but it can reduce blood flow to your heart muscle and worsen existing coronary artery disease. Some people experience chest pain similar to a heart attack due to inadequate blood flow to the heart muscle. This is why doctors often check your coronary arteries before valve replacement surgery.

Is TAVR as good as open-heart surgery?

Recent studies show TAVR is equally effective as surgical valve replacement for most patients, with lower short-term risks but potentially shorter valve durability. TAVR is now approved for patients of all risk levels, though the choice between procedures depends on your individual anatomy, age, and other health conditions.

Can diet changes help my aortic stenosis?

While diet can't reverse aortic stenosis, maintaining a heart-healthy diet may slow progression and improve your overall cardiovascular health. Focus on limiting sodium to reduce blood pressure, eating plenty of fruits and vegetables, and avoiding excessive saturated fats. Some studies suggest adequate vitamin K intake might be beneficial for valve health.

What happens if I choose not to have valve replacement surgery?

Without treatment, severe symptomatic aortic stenosis has a poor prognosis, with average survival of only 2-5 years after symptoms begin. However, this varies greatly between individuals, and some people may live longer with careful medical management. Your doctor can help you understand the risks and benefits of different approaches based on your specific situation.

How long do replacement valves last?

Biological valves typically last 15-20 years, sometimes longer, especially in older patients. Mechanical valves can last a lifetime but require permanent blood thinner medication. The choice often depends on your age at the time of surgery and your personal preferences regarding medication and future procedures.

Can I travel by airplane with aortic stenosis?

Most people with mild to moderate aortic stenosis can travel safely by airplane. However, if you have severe stenosis or symptoms, discuss travel plans with your cardiologist first. The reduced cabin pressure and limited medical facilities during flight could pose risks if you have unstable symptoms.

Will my children inherit aortic stenosis?

Most cases of aortic stenosis aren't directly inherited, but bicuspid aortic valve does run in families. If you were born with a bicuspid valve, your children have about a 10% chance of having the same condition. Your cardiologist may recommend family members get screened with an echocardiogram.
