What is aortic stenosis?
A person with aortic stenosis has abnormal narrowing of the aortic valve. A normal aortic valve allows blood to flow from the heart, into the aorta. The aortic valve closes to prevent the backflow of blood from the aorta into the heart. The narrowing of the aortic valve interferes with the flow of blood from the left ventricle into the aorta. Aortic stenosis places stress on the heart, as it works to overcome the narrowed passageway. Some people are born with this condition or they may develop it later in life.

What are the symptoms of aortic stenosis?

How does the doctor treat aortic stenosis?
Treatment for aortic stenosis includes medications to control symptoms and heart surgery to replace the aortic valve
