What is Aortic Stenosis (AS)?
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.
Typical Symptoms of Aortic Stenosis (AS)
- Fainting
- Wheezing or whistling sounds when breathing
- Breathing is harder when lying down, improves when sitting up
- Waking up at night struggling to breathe
- History of heart murmur
- Left-sided chest pain
- History of heart failure
- Difficulty breathing
Diagnostic Questions for Aortic Stenosis (AS)
Your doctor may ask these questions to check for this disease:
- Have you fainted recently?
- Do you experience wheezing or whistling sounds when breathing?
- Does your breathing improve when you sit up from lying down?
- Do you wake up at night struggling to breathe?
- Have you been diagnosed with heart murmur?
Treatment of Aortic Stenosis (AS)
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.
