What is aortic stenosis?
A healthy, normal heart valve allows blood to flow in one direction without obstruction. When a valve is narrowed, it is said to have “stenosis”.
The most common valve problem is the narrowing of the aortic valve that lies between the left ventricle and the aorta. This is called aortic stenosis.
Aortic stenosis is usually due to calcium building up on the valve lea ets causing them to become rigid. Blood flow from your heart to your aorta and onward to the rest of your body is obstructed.
When the aortic valve is obstructed, your heart needs to work harder to pump blood to your body.
