Causes of Aortic Stenosis

Aortis Stenosis is characterized by a narrowing of the aortic valve. In this video, Dr. Preeti Parikh outlines the three main causes of Aortic Stenosis. These causes include calcification of the heart valve, a defect in the way the valve was formed at birth, and scarring due to illness.

Calcification occurs when deposits of calcium, a mineral in the blood, builds up around the aortic valve. This build up can make the valve brittle and thick. Aortic Stenosis typically affects people over the age of 60.

Some people can develop Aortis Stenosis because they were born with a deformed aortic valve. Generally, those born with a deformed valve have a family history of aortic stenosis. To gauge your risk, be sure to find out if anyone in your immediate family has this condition.  

Scarring on the aortic valve can also cause it to narrow, which can result from rheumatic fever. This is an atypical cause of Aortic Stenosis. Rheumatic fever has been all but eradicated in the United States.

Unfortunately, Aortis Stenosis is difficult to prevent, so be sure to speak to your doctor to gauge if you are at risk.
