Aortic Stenosis: What You Need to Know

Narrowing of the Aortic Valve

Aortic stenosis is a type of heart valve disease. The aortic valve opens to allow blood to flow forward to the body and closes tightly so blood does not leak backwards into the heart. Aortic stenosis is a narrowing of the aortic valve opening. It prevents blood from flowing easily and makes the heart work harder. Read on to learn what you need to know about aortic stenosis.
