Short answer · Medically reviewed summary · Last updated: 2026-05-08
A Bicuspid Aortic Valve (BAV) is a congenital heart defect where the aortic valve has two leaflets instead of the usual three, often remaining asymptomatic for years until detected via a heart murmur or imaging. To know if you have a Bicuspid Aortic Valve, you must undergo specific cardiac imaging, as physical symptoms often do not appear until the valve begins to narrow or leak in adulthood. What are the early signs of Bicuspid Aortic Valve? Most individuals with a Bicuspid Aortic Valve do not experience symptoms early in life.

A Bicuspid Aortic Valve (BAV) is a congenital heart defect where the aortic valve has two leaflets instead of the usual three, often remaining asymptomatic for years until detected via a heart murmur or imaging. To know if you have a Bicuspid Aortic Valve, you must undergo specific cardiac imaging, as physical symptoms often do not appear until the valve begins to narrow or leak in adulthood.
What are the early signs of Bicuspid Aortic Valve?
Most individuals with a Bicuspid Aortic Valve do not experience symptoms early in life. Because this condition is structural, you cannot self-diagnose through physical sensation alone. However, as the valve ages, it may lead to aortic stenosis (narrowing) or regurgitation (leaking). If you notice unexplained fatigue, lightheadedness, chest discomfort during exertion, or a heart murmur detected during a routine physical, these warrant further investigation.
How is Bicuspid Aortic Valve diagnosed?
Diagnosis requires visualization of the valve structure. If a physician suspects a Bicuspid Aortic Valve, they will typically order an echocardiogram (an ultrasound of the heart). This is the gold standard for confirming the anatomy of your valve. If you are concerned, ask your primary care provider for an auscultation of your heart to listen for the characteristic "click" or murmur associated with Bicuspid Aortic Valve.
When should I seek urgent medical attention?
While many people live full lives with a Bicuspid Aortic Valve, certain "red flag" symptoms require immediate emergency evaluation:
- Fainting or loss of consciousness (syncope)
- Sudden, severe chest pain or pressure
- Unexplained shortness of breath at rest
- Palpitations accompanied by dizziness
How can I advocate for my heart health?
If you have a family history of heart valve disease or aortic aneurysms, be proactive. You can advocate for yourself by requesting a baseline echocardiogram to rule out a Bicuspid Aortic Valve. If your concerns are dismissed, ask specifically: "Given my family history, could we perform an echocardiogram to screen for structural valve abnormalities?"
Next steps
- Schedule an appointment with a cardiologist to discuss your cardiac concerns.
- Ask your family members about any history of "leaky" or "narrow" heart valves.
- Join the 142 members of the DiseaseMaps.org community living with Bicuspid Aortic Valve to share experiences.
- Maintain regular blood pressure monitoring, as hypertension can exacerbate the strain on a bicuspid valve.
