In aortic stenosis, the valve in a major blood artery branching off the heart (the aorta) is narrowed. This prevents the valve from fully opening and leads to decreased blood flow out of the heart. As a result, the heart has to work harder to get the same amount of blood out. Two things end up happening: the heart eventually starts to fail or you develop symptoms like chest pain, dizziness or feeling like you will pass out because not enough blood is getting to your brain. The main cause is the accumulation of calcium deposits in the valve which increases with age.
Your doctor may ask these questions to check for this disease:
Mild to moderate cases that do not have symptoms usually do not require treatment, rather ongoing monitoring of the stenosis. Severe aortic stenosis requires replacement of the valve.

Q.
Short of Breath? Why Your Aortic Valve is Narrowing + Medically Approved Next Steps
A.
Shortness of breath can be a key warning sign of aortic stenosis, a narrowing of the aortic valve that forces the heart to work harder and can become life threatening once symptoms appear, especially in adults over 65; doctors often hear a murmur on exam and confirm the diagnosis and severity with an echocardiogram. Do not wait, schedule a prompt evaluation, track your symptoms, ask about an echocardiogram, and know that severe cases are treated with valve replacement by TAVR or surgery, while chest pain, fainting, or severe breathlessness require emergency care. There are several factors to consider; see the complete guidance below.
