Aortis Stenosis occurs due to a narrowing of the aortic valve. In this video, Dr. Preeti Parikh outlines the three main causes of Aortis 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.

00:02.619 --> 00:07.517
Aortic stenosis occurs through
a narrowing of the aortic valve,
00:07.517 --> 00:11.357
but what causes this
narrowing in the first place?
00:11.357 --> 00:16.669
Hi, I'm Dr. Preeti Parikh,
chief medical editor of Healthy Nation.
00:16.669 --> 00:19.709
There are three main
causes of aortic stenosis.
00:19.709 --> 00:22.050
Calcification of the heart valve,
00:22.050 --> 00:27.049
a defect in the way the valve was formed
at birth and scarring due to illness.
00:27.049 --> 00:31.829
Aortic stenosis caused by calcification
occurs when deposits of calcium,
00:31.829 --> 00:35.430
a mineral found in the blood,
build up around the valve.
00:35.430 --> 00:38.850
This build up can make
the valve brittle and thick.
00:38.850 --> 00:42.150
Narrowing the opening for
the blood to flow through.
00:42.150 --> 00:46.320
People who develop aortic stenosis due
to this calcium build up are generally
00:46.320 --> 00:48.160
in their sixties and seventies.
00:49.350 --> 00:52.950
Some people are predisposed to developing
aortic stenosis because they were
00:52.950 --> 00:55.580
born with a deformed aortic valve.
00:55.580 --> 00:59.460
For these people, the valve can be
narrowed due to unusual formation.
00:59.460 --> 01:04.080
Calcification can also happen more quickly
in those born with a deformed valve.
01:04.080 --> 01:07.070
Generally, people born with
a deformed valve have a family
01:07.070 --> 01:09.180
history of aortic stenosis, so
01:09.180 --> 01:13.740
it's important to find out if anyone in
your immediate family has this condition.
01:13.740 --> 01:17.910
Finally, scarring on the valve
can cause it to narrow as well.
01:17.910 --> 01:21.780
Scarring is not typical since it
is the result of rheumatic fever,
01:21.780 --> 01:24.670
a condition that is now rare in the US.
01:24.670 --> 01:28.770
These scars may also become calcified
quicker than healthy tissue.
01:28.770 --> 01:32.180
If you think you may be at risk,
talk with your doctor.
01:32.180 --> 01:35.590
Be sure to share your medical and
01:35.590 --> 01:39.065
Unfortunately, aortic stenosis
is difficult to prevent.
01:39.065 --> 01:45.050
But together, you and your doctor can
monitor any early signs specific to you.
01:45.050 --> 01:46.239
Thanks for watching.
