Aortic Valve Prolapse: Definition and Symptoms

Aortic valve prolapse, also known as aortic regurgitation or insufficiency, is a condition where the aortic valve does not close properly, allowing blood to flow backward from the body's main artery, called the aorta.

• Definition: Aortic valve prolapse is defined as downward displacement of 1 or more leaflet tips below a line joining the points of attachment of the AV leaflets [1].
• Symptoms: The symptoms of aortic valve prolapse can include:
  • Chest pain or tightness
  • Dizziness
  • Fainting
  • Fatigue after activity or having less ability to be active
  • Irregular heartbeat
  • Shortness of breath [3]
• Causes and Effects: The downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE can cause misalignment of the cusps, leading to severe valve distortion and aortic regurgitation [6].

Aortic Valve Regurgitation

Aortic valve regurgitation is another term for aortic insufficiency, where the aortic valve does not close properly. This condition can lead to a range of symptoms, including shortness of breath, chest discomfort, feeling faint, fatigue, and weakness [9].

In summary, aortic valve prolapse is a condition where the aortic valve does not close properly, leading to backward flow of blood from the aorta. The symptoms can include chest pain, dizziness, fainting, fatigue, irregular heartbeat, and shortness of breath.

Aortic valve prolapse, also known as aortic regurgitation, can manifest in various ways, depending on the severity of the condition. Here are some common signs and symptoms:

• Shortness of breath: This is one of the most frequent complaints among people with aortic valve prolapse. It may occur when exerting oneself or even while lying flat [7][8].
• Fatigue: As the heart works harder to compensate for the faulty valve, fatigue can become a significant issue [3][9].
• Chest pain: Some individuals may experience chest discomfort or pain, which can be a symptom of more severe aortic regurgitation [4][5].
• Palpitations: Skipped beats or an unusual flip-flop feeling in the chest can occur due to the irregular blood flow [6].
• Edema: Swelling of the ankles, feet, or abdomen can happen as fluid accumulates in the body due to the inefficient valve [5].
• Weakness or dizziness: As the condition worsens, people may feel weak or experience dizziness due to reduced blood circulation [6].

It's essential to note that some individuals with aortic valve prolapse might not exhibit any symptoms at all, especially if the condition is mild. However, as the disease progresses, these signs and symptoms can become more pronounced.

Diagnostic Tests for Aortic Valve Disease

Aortic valve disease, including conditions like aortic valve regurgitation and stenosis, can be diagnosed through various tests. Here are some of the diagnostic tests used to diagnose aortic valve disease:

• Physical Exam: Your doctor will review your medical history, perform a physical exam, and run diagnostic tests to make a diagnosis. They will check your blood pressure and pulse, and use a stethoscope to listen for a characteristic heart murmur or other signs of aortic valve disease [4].
• Echocardiogram: An echocardiogram is the gold standard for diagnosing aortic valve disease. This test uses high-frequency sound waves (ultrasound) to take pictures of your heart and valves, showing how blood flows through them [5, 8]. It can also show if the heart muscle is weakened.
• Exercise Testing: Exercise testing, or stress test, can provide valuable information in people with valvular heart disease, especially in those whose symptoms may be difficult to assess. This test measures your heart's response to exercise and can help determine the severity of aortic valve disease [3].
• Cardiac Computerized Tomography (CT) Scan: A cardiac CT scan creates a detailed image of your heart and valves using a special type of X-ray. It can show if there are any blockages or other abnormalities in the blood vessels leading to the heart.
• Lab Tests: While lab tests cannot diagnose aortic insufficiency, they may help check for other causes of symptoms.

Staging Aortic Valve Disease

After testing confirms a diagnosis of aortic valve disease, your healthcare team may tell you the stage of disease. Staging helps determine the most appropriate treatment. The stage of heart valve disease depends on many things, including symptoms, disease severity, the structure of the valve or valves, and blood flow through the heart and lungs [10].

Aortic valve prolapse, also known as aortic regurgitation, can be treated with medication to alleviate symptoms and slow down the progression of the condition.

Current treatment options

According to medical research, diuretics and vasodilators are often prescribed to manage symptoms in patients who are not suitable for surgery [3]. These medications help reduce fluid buildup in the body and lower blood pressure, which can ease symptoms such as shortness of breath and fatigue.

• Diuretics: Medications like furosemide (Lasix) and hydrochlorothiazide (HCTZ) can be used to remove excess fluids from the body [3].
• Vasodilators: Drugs like hydralazine and minoxidil can help relax blood vessels, reducing blood pressure and alleviating symptoms [3].

Limitations of drug treatment

While medication can provide relief for some patients, it is essential to note that surgery may be necessary in severe cases or if symptoms persist despite medical treatment [1]. Additionally, long-term use of diuretics and vasodilators can have side effects such as electrolyte imbalances and increased risk of kidney stones.

Surgical alternatives

In many cases, surgical repair or replacement of the aortic valve is recommended to restore normal heart function and prevent complications [4][5]. Surgery can cure aortic insufficiency and relieve symptoms, unless other complications arise [5].

Aortic valve prolapse, also known as aortic regurgitation, can be caused by various factors. Here are some possible differential diagnoses:

• Primary damage to the valve leaflets: This can occur due to conditions such as rheumatic heart disease, endocarditis, or trauma to the valve.
• Dilation of the aortic root: When the aortic root becomes enlarged, it can prevent the valve from closing properly, leading to regurgitation. This can be caused by conditions such as hypertension, atherosclerosis, or Marfan syndrome.
• Aortic dissection: A tear in the inner layer of the aorta can cause blood to flow backward into the left ventricle, leading to regurgitation.
• Mitral valve prolapse: Although not directly related to the aortic valve, mitral valve prolapse can sometimes be associated with aortic regurgitation due to shared risk factors such as connective tissue disorders.

According to [3], aortic root and ascending aortic dilatation are indicators associated with risk of aortic dissection. Additionally, [9] states that aortic regurgitation results from abnormalities of the aortic leaflets, their supporting structures in the aortic root and annulus, or both.

It's essential to note that these differential diagnoses may not be mutually exclusive, and a combination of factors can contribute to the development of aortic valve prolapse. A thorough medical evaluation, including imaging studies and echocardiography, is necessary to determine the underlying cause of aortic regurgitation.
