Aortic Stenosis Murmur: Symptoms, Diagnosis & Treatment


What is Aortic Stenosis Murmur?

Aortic stenosis is a cardiovascular condition that occurs when the aortic valve, which separates the left ventricle and the aorta, narrows.

This can obstruct blood flow from the left ventricle to the aorta, leading to various symptoms and complications. A common manifestation of aortic stenosis is the presence of a characteristic heart murmur, which can be detected during physical examination.

The aortic stenosis murmur is caused by turbulent blood flow through the stenotic valve, and it can provide important diagnostic information for clinicians.

The aortic stenosis murmur is typically described as a harsh, crescendo-decrescendo sound that is best heard over the right second intercostal space, corresponding to the aortic valve’s location.

The murmur may radiate to the neck or the carotid arteries, and a thrill can accompany it, a palpable vibration felt over the chest wall.

The intensity and quality of the murmur can vary depending on the stenosis’s severity and the individual patient’s characteristics.

Overall, the aortic stenosis murmur is an important clinical sign that can aid in diagnosing and managing this common cardiovascular condition.

Is Heart Murmur A Comorbidity?

A heart murmur is not a comorbidity in and of itself, but it can be a symptom of an underlying condition that may be considered a comorbidity.

Comorbidity means the presence of one or more additional medical conditions in a patient with a primary condition. For example, a patient who has a history of heart disease and diabetes would be considered to have comorbidities.

In the case of heart murmurs, they can be caused by various underlying conditions, including congenital heart defects, valve disease, and hypertension.

These conditions may themselves be comorbidities of other conditions such as diabetes, kidney disease, or obesity. Therefore, a heart murmur can indicate an underlying comorbidity, but it is not a comorbidity itself.

According to the American Heart Association, aortic stenosis is one of the most common causes of heart murmurs in adults.

Aortic stenosis is often seen in older adults, particularly those with a history of hypertension, smoking, or diabetes, which are all potential comorbidities.

Symptoms of Aortic Stenosis Murmur

We will discuss the symptoms associated with aortic stenosis murmur in detail.

A primary symptom of aortic stenosis murmur is shortness of breath, which can occur during exertion or even at rest in severe cases.

This is due to the reduced amount of blood that flows through the narrowed aortic valve, leading to decreased oxygen delivery to the body.

Aortic stenosis patients may also experience chest pain or discomfort, typically felt in the chest or upper abdomen and described as pressure, tightness, or burning.

Another common symptom of aortic stenosis murmur is fainting or syncope, which can occur due to decreased blood flow to the brain.

This can be a serious symptom and should be evaluated by a healthcare professional immediately. Patients may also experience palpitations or a rapid heartbeat caused by changes in the heart’s electrical activity due to the stenotic valve.

In severe cases of aortic stenosis, patients may also experience heart failure, which can cause symptoms such as swelling in the legs or abdomen, fatigue, and a decreased ability to exercise.

In addition, patients may experience sudden cardiac death, which can occur due to irregular heart rhythms or other complications of stenosis.

Not all patients with aortic stenosis murmur will experience symptoms, and the severity of symptoms can vary depending on the extent of the stenosis and the individual patient’s health status.

However, if you experience any of the symptoms mentioned above, it is important to seek medical attention to receive an accurate diagnosis and appropriate treatment.

Diagnostic Tests for Aortic Stenosis Murmur

The diagnostic tests for aortic stenosis murmur may include the following:


This non-invasive test uses sound waves to create images of the heart. Echocardiography can help determine the degree of stenosis and the condition of the aortic valve.

Electrocardiography (ECG):

This test records the heart’s electrical activity and can help identify abnormal rhythms, which may be associated with aortic stenosis.

Cardiac catheterization

This invasive test involves inserting a catheter into a blood vessel and guiding it to the heart to measure the pressure inside the heart and blood vessels.

Chest X-ray:

This imaging test can help identify signs of heart enlargement or fluid buildup in the lungs.

CT scan or MRI:

These imaging tests can provide detailed images of the heart and aorta and may be used to help diagnose aortic stenosis and assess the degree of stenosis.

Diagnosis of Aortic Stenosis Murmur

Diagnosing aortic stenosis murmur involves a combination of patient history, physical examination, and diagnostic testing.

Aortic stenosis is a serious condition that can lead to significant health complications, so it is important to diagnose the condition and determine appropriate treatment options accurately.

This response will discuss the diagnostic methods used to diagnose aortic stenosis murmur.

The first step in diagnosing aortic stenosis murmur is to take a detailed patient history. This includes asking about any symptoms the patient is experiencing and their medical history, medications, and lifestyle factors.

Patients with risk factors such as a family history of valve disease, congenital heart defects, or a history of rheumatic fever may be more likely to develop aortic stenosis.

Physical examination is also an important part of the diagnostic process. A stethoscope during a routine physical exam can often detect aortic stenosis murmur.

The murmur is typically heard as a harsh or rasping sound during the systolic phase of the cardiac cycle, which is when the heart is contracting and pushing blood out of the left ventricle.

The intensity of the murmur may vary depending on the degree of stenosis, with more severe stenosis resulting in a louder murmur.

In addition to physical examination, diagnostic tests such as echocardiography, electrocardiography (ECG), and cardiac catheterization may be used to confirm a diagnosis of aortic stenosis murmur.

Echocardiography is a non-invasive imaging test that uses sound waves to produce images of the heart and can provide detailed information about the structure and function of the heart valves.

ECG can help identify abnormal heart rhythms associated with aortic stenosis, while cardiac catheterization involves inserting a thin tube into the heart to measure pressure and blood flow. 

Treatment of Aortic Stenosis Murmur

The treatment of aortic stenosis murmur depends on the severity of the stenosis and the presence of symptoms. Close monitoring and regular follow-up appointments with a healthcare provider may be sufficient in mild cases.

However, treatment may be necessary in more severe cases to relieve symptoms and prevent complications. In this response, we will discuss the treatment options for aortic stenosis murmur.

Medical management may be used to manage symptoms associated with aortic stenosis murmur, including shortness of breath and chest pain.

This may include medications such as diuretics to reduce fluid buildup in the body and beta-blockers to help control heart rate and blood pressure. However, medications alone are not typically sufficient to treat severe cases of aortic stenosis.

Surgical treatment options for aortic stenosis include aortic valve replacement (AVR) and transcatheter aortic valve replacement (TAVR). AVR involves surgically replacing the diseased aortic valve with a prosthetic valve. TAVR is an invasive procedure that involves inserting a new valve through a small incision in the groin and guiding it to the heart using a catheter.

In addition to surgical options, balloon valvuloplasty may sometimes be used to widen the aortic valve. This involves inserting a balloon catheter into the narrowed valve and inflating it to widen the opening.

However, this procedure is typically reserved for patients who are not candidates for surgery or as a temporary measure to stabilize patients before surgery.

Lifestyle changes may also be recommended to manage symptoms and improve overall health. This may include regular exercise, a heart-healthy diet, and avoiding tobacco and excessive alcohol consumption.


In conclusion, aortic stenosis murmur is a serious medical condition that can lead to significant health complications. It is important to accurately diagnose and treat the condition to prevent serious complications and improve quality of life.

If you are experiencing symptoms such as shortness of breath, chest pain, or palpitations, it is important to seek medical attention to receive an accurate diagnosis and appropriate treatment.
