As the aortic valve narrows, the left ventricle has to work harder to pump blood out through the valve. To do this extra work, the muscles in the ventricle walls become thicker. This can lead to chest pain.
As the pressure continues to rise, blood may back up into the lungs. Severe aortic stenosis can limit the amount of blood that reaches the brain and the rest of the body.

Aortic Stenosis Causes
Aortic stenosis, a type of structural heart disease, may be present from birth (congenital), but most often develops later in life.
Aortic stenosis mainly occurs due to the buildup of calcium deposits that narrow the valve. The problem mostly affects older people.
Calcium buildup of the valve happens sooner in people who are born with abnormal aortic or bicuspid valves. In the United States, 1.5 million people suffer from aortic stenosis - 500,000 of those suffer from severe aortic stenosis.
Aortic Stenosis Symptoms
Most people with aortic stenosis do not develop symptoms until the disease is advanced. Symptoms of sever aortic stenosis include:
- Chest pain or tightness
- Feeling faint or fainting with exertion
- Shortness of breath (especially with exertion)
- Fatigue (especially during times of increased activity)
- Heart palpitations
- Heart murmur
Aortic Stenosis Diagnosis
Your doctor will most likely hear a heart murmur, click, or other abnormal sound through their stethoscope. He or she may be able to feel a vibration or movement when placing a hand over your heart.
After an initial detection from your physical exam, your doctor may choose to follow-up with further tests that may include:
Aortic Stenosis Treatment
If valve damage is mild, your doctor may decide to take a “wait and see” approach or treat your symptoms with medication. If damage to the valve is more severe, surgery to replace the valve may be needed.
Surgical options could include open heart surgery or minimally-invasive surgery. Wake Forest Baptist interventional cardiologists are some of the most experienced in the state at an innovative new minimally-invasive surgery for aortic stenosis called transcatheter aortic valve replacement (TAVR).
A number of risk factors and considerations go into the decision to have minimally-invasive or open surgery. Your doctor will work with you to create a treatment plan that works for your individual needs. All of our patients receive pre-operative counseling to help them understand the risks and benefits of procedures.
