How is Bicuspid Aortic Valve diagnosed?

Bicuspid Aortic Valve (BAV) is most commonly diagnosed via an echocardiogram, which uses ultrasound waves to visualize the valve structure and identify the presence of only two leaflets instead of the normal three. Because BAV is often asymptomatic in early stages, diagnosis frequently occurs incidentally during routine physical exams or when investigating heart murmurs, though early detection is critical to monitor for potential complications like aortic dilation.

How is Bicuspid Aortic Valve diagnosed?

The diagnostic process for Bicuspid Aortic Valve typically begins when a physician hears a heart murmur during a standard physical examination. To confirm the diagnosis, specialists utilize non-invasive imaging. The most common diagnostic tools include:

• Transthoracic Echocardiogram (TTE): The gold standard for initial visualization of the valve leaflets.


• Transesophageal Echocardiogram (TEE): Provides higher-resolution images if the TTE is inconclusive.


• Cardiac MRI or CT Angiography: Used to assess the dimensions of the aorta, as patients with Bicuspid Aortic Valve have a higher risk of aortic aneurysm.

Is genetic testing required for Bicuspid Aortic Valve?

While BAV is the most common congenital heart defect, affecting approximately 0.5% to 2% of the general population, it is not always diagnosed through genetic testing. However, because it has a strong familial component, clinical geneticists may recommend screening for first-degree relatives of those diagnosed with Bicuspid Aortic Valve. Genetic testing is usually reserved for cases where BAV is suspected to be part of a larger syndrome, such as Loeys-Dietz or Marfan syndrome.

What is the typical diagnostic journey?

Many individuals with Bicuspid Aortic Valve experience a "diagnostic odyssey" because the condition can remain silent for decades. Patients often feel frustrated when symptoms like fatigue or palpitations are dismissed before a specialist finally orders an echocardiogram. At DiseaseMaps.org, 142 community members have shared their experiences, highlighting that persistence is vital when you suspect your cardiac symptoms are not being fully investigated.

Which specialists should I consult?

If you suspect you have Bicuspid Aortic Valve, you should be under the care of a cardiologist. If you have been diagnosed, it is important to seek a specialist who focuses on valvular heart disease or adult congenital heart disease to ensure you receive appropriate long-term monitoring for potential aortic complications.

Next steps

• Consult a board-certified cardiologist to request a formal echocardiogram.


• Request that your first-degree relatives undergo screening, as Bicuspid Aortic Valve is hereditary.
