What is aortic stenosis?

Aortic stenosis is a progressive condition caused by a narrowing of the aortic valve, which prevents normal blood flow. Because the condition will get worse with time, doctors will measure it as mild, moderate, or severe (depending on how damaged the valve is). The condition affects more than 2.5 million people over the age of 75 in the United States.1,2
