Aortic valve disease: Causes, Risk Factors, Symptoms, Treatment

Aortic valve disease

Aortic valve disease is a serious condition that affects the heart's ability to function properly. It occurs when the aortic valve, which controls blood flow from the heart to the rest of the body, becomes damaged or diseased. This can lead to symptoms such as chest pain, shortness of breath, and fatigue. 

Symptoms of Aortic Valve Disease

If you suspect you have aortic valve disease or have been diagnosed with it, it's essential to consult with a cardiologist.


The causes of aortic valve disease can be categorized into congenital, acquired, and other contributing factors:

Congenital Causes

  • Bicuspid Aortic Valve (BAV): This is the most common congenital cause. Normally, the aortic valve has three cusps, but a bicuspid aortic valve has only two. This can lead to early wear and tear, calcification, and a higher risk of developing aortic stenosis or regurgitation.
  • Unicuspid or Quadricuspid Aortic Valve: Rare congenital anomalies where the aortic valve has one or four cusps, respectively, which can also lead to dysfunction over time.

Acquired Causes

  • Degenerative/Calcific Aortic Valve Disease: Often seen in older adults, this condition involves the buildup of calcium deposits on the valve, leading to stiffening and narrowing (stenosis). It's similar to the process of atherosclerosis.
  • Rheumatic Heart Disease: Resulting from untreated or poorly treated streptococcal infections (such as strep throat), this condition can cause inflammation and scarring of the aortic valve, leading to stenosis or regurgitation.
  • Endocarditis: Infection of the heart valves, often caused by bacteria, can damage the aortic valve, leading to regurgitation or, less commonly, stenosis.
  • Aortic Aneurysm or Dissection: Conditions affecting the aorta can involve the aortic valve, especially when the aortic root is affected, potentially leading to valve regurgitation.

Other Contributing Factors

  • Hypertension: High blood pressure can contribute to the degeneration and calcification of the aortic valve.
  • Marfan Syndrome and Other Connective Tissue Disorders: These genetic conditions can affect the aortic root and valve structure, leading to aortic regurgitation.
  • Chronic Kidney Disease: Patients with long-term kidney disease are at higher risk for calcific aortic valve disease due to altered calcium metabolism.
  • Hypercholesterolemia and Hyperlipidemia: High levels of cholesterol and lipids in the blood can contribute to the calcific process on the valve.

Risk Factors

Certain factors increase the likelihood of developing aortic valve disease:

Age: Risk increases with age, especially for degenerative and calcific causes.

Family History: Genetic predisposition can play a role.

Lifestyle Factors: Smoking, poor diet, and lack of exercise contribute to atherosclerosis and can indirectly affect valve health.


There are two main types of aortic valve disease: aortic stenosis and aortic regurgitation. Here are some common symptoms associated with each:

Aortic Stenosis:

Chest pain or tightness: This may be experienced during physical activity or when the heart is working harder.

Shortness of breath: Especially during exertion or when lying flat.

Fatigue: Feeling tired or weak, often due to the heart having to work harder to pump blood through the narrowed valve.

Fainting or dizziness: Especially with exertion or when moving from sitting to standing (orthostatic hypotension).

Heart palpitations: Sensation of rapid, fluttering, or pounding heartbeats.

Heart murmur: A doctor may detect an abnormal sound during a physical examination.

Aortic Regurgitation (Insufficiency):

Shortness of breath: Especially during physical activity or lying flat.

Fatigue: Due to the heart's reduced ability to efficiently pump blood to the body.

Heart palpitations: Sensation of rapid, fluttering, or pounding heartbeats.

Chest pain: May occur due to the heart's increased workload.

Dizziness or fainting: Especially with exertion.

Heart murmur: A doctor may detect an abnormal sound during a physical examination.

Need an Appointment?


Here are some common steps in the diagnostic process:

Medical History Review: The doctor will ask about your symptoms, medical history, and any risk factors you may have for heart disease, such as high blood pressure, high cholesterol, or a family history of heart problems.

Physical Examination: During the physical exam, the doctor will listen to your heart with a stethoscope to check for any abnormal sounds, such as a heart murmur, which may indicate a problem with the aortic valve.

Imaging Tests:

Echocardiogram: This is the primary test used to diagnose aortic valve disease. It uses sound waves to create a picture of the heart and can show the structure and function of the aortic valve.

Transesophageal Echocardiogram (TEE): In some cases, a TEE may be performed to get a closer look at the heart structures. In this procedure, a small ultrasound probe is passed down the throat and into the esophagus to get a clearer image of the heart.

Cardiac MRI or CT Scan: These imaging tests can provide detailed images of the heart and may be used to evaluate the aortic valve and surrounding structures.

Electrocardiogram (ECG or EKG): This test records the electrical activity of the heart and can help identify any abnormal rhythms or signs of heart damage.

Exercise Stress Test: In some cases, an exercise stress test may be performed to evaluate how well your heart functions during physical activity.

Cardiac Catheterization: This invasive procedure involves inserting a thin, flexible tube called a catheter into a blood vessel and guiding it to the heart. It may be used to measure the pressure within the heart chambers and blood vessels and to assess the severity of the valve disease.

Blood Tests: Blood tests may be done to check for certain markers of heart damage or to evaluate your overall health.


The treatment for aortic valve disease depends on the severity of the condition and the symptoms it causes. Here are some common treatment options:


Diuretics: These medications help reduce fluid buildup in the body, which can help alleviate symptoms like shortness of breath and swelling.

Blood pressure medications: Medications to control high blood pressure can help reduce the workload on the heart and improve symptoms.

Beta-blockers: These medications can help slow the heart rate and reduce strain on the heart muscle.

Anticoagulants: In some cases, blood-thinning medications may be prescribed to reduce the risk of blood clots, especially if there is associated atrial fibrillation.

Interventional Procedures:

Balloon Valvuloplasty: This minimally invasive procedure involves inserting a catheter with a balloon at its tip into the narrowed valve and inflating it to widen the valve opening.

Transcatheter Aortic Valve Replacement (TAVR): TAVR is a minimally invasive procedure used to replace a diseased aortic valve. A new valve is inserted through a catheter and placed inside the diseased valve, without the need for open-heart surgery.

Surgical Aortic Valve Replacement (SAVR): In cases where the valve is severely damaged or other procedures are not feasible, open-heart surgery may be necessary to replace the diseased valve with a mechanical or tissue valve.

Preventive Measures

Preventive measures for aortic valve disease primarily focus on reducing risk factors for heart disease and maintaining overall heart health. Here are some preventive measures:

Healthy Lifestyle Choices:

Maintain a Healthy Diet: Eat a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit intake of processed foods, saturated fats, cholesterol, and sodium.

Regular Exercise: Aim for at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity exercise per week, as recommended by guidelines.

Maintain a Healthy Weight: Being overweight or obese increases the risk of heart disease, including aortic valve disease. Aim for a healthy weight through a combination of diet and exercise.

Quit Smoking: Smoking is a significant risk factor for heart disease, including aortic valve disease. Seek support and resources to quit smoking if you are a smoker.

Limit Alcohol Consumption: Excessive alcohol consumption can contribute to high blood pressure and heart disease. Limit alcohol intake to moderate levels as recommended by health guidelines.

Manage Chronic Conditions:

Control High Blood Pressure: Monitor blood pressure regularly and work with your healthcare provider to manage hypertension through lifestyle changes and medication if needed.

Manage High Cholesterol: Keep cholesterol levels within a healthy range through diet, exercise, and medication if prescribed by a healthcare provider.

Control Diabetes: Maintain blood sugar levels within target ranges through lifestyle modifications, medication, and regular monitoring.

Treat Sleep Apnea: If you have sleep apnea, seek treatment to improve sleep quality and reduce the risk of heart disease.

Regular Health Check-ups:

Schedule regular check-ups with your healthcare provider to monitor your heart health, blood pressure, cholesterol levels, and overall cardiovascular risk.

Discuss any symptoms or concerns related to heart health with your healthcare provider promptly.

Frequently Asked Questions
Aortic valve disease is a serious condition that affects the heart's ability to function properly. It occurs when the aortic valve, which controls blood flow from the heart to the rest of the body, becomes damaged or diseased. This can lead to symptoms such as chest pain, shortness of breath, and fatigue.
The most common symptoms of aortic valve disease is chest pain or discomfort. This can range from mild to severe and may be felt as pressure, tightness, or squeezing sensation in the chest. Another symptom to watch out for is fatigue or weakness. Aortic valve disease can cause decreased blood flow and oxygen supply to various parts of the body, leading to feelings of exhaustion and reduced stamina.
There are several factors that can contribute to the development of Aortic Valve Disease. One common cause is age-related degeneration, where the valve becomes thickened and stiff over time. This can lead to narrowing of the valve opening, known as aortic stenosis. Another possible cause is congenital abnormalities, which means that a person is born with an abnormal aortic valve structure or function.
Several key risk factors have been identified in relation to aortic valve disease. Age is one such factor, as the risk tends to increase with advancing age. Additionally, gender plays a role, with men being more susceptible to developing this condition than women. Other notable risk factors include a history of certain medical conditions such as high blood pressure, high cholesterol levels, and diabetes. These underlying health issues can contribute to the development of aortic valve disease over time.
One of the primary methods used for diagnosing aortic valve disease is echocardiography. This non-invasive imaging technique allows doctors to visualize the structure and function of the heart, including the aortic valve. By using sound waves, echocardiography provides detailed information about the valve's size, shape, and movement. It also helps determine if there are any abnormalities such as stenosis (narrowing) or regurgitation (leakage).
One common treatment approach is medication therapy, which aims to control symptoms and prevent further complications. Medications such as diuretics, beta-blockers, and ACE inhibitors may be prescribed to manage symptoms like high blood pressure or heart failure. In more severe cases or when medications are not enough to alleviate symptoms, surgical interventions may be necessary.
One of the key factors in preventing aortic valve disease is maintaining a healthy lifestyle. This includes adopting a balanced diet that is low in saturated fats, cholesterol, and sodium. Incorporating plenty of fruits, vegetables, whole grains, and lean proteins into your meals can help keep your heart healthy and reduce the risk of developing valve disease. Regular exercise is also crucial in preventing aortic valve disease.
