What is a heart valve and why is it important?
Your heart has 4 valves- Aortic, Pulmonary, Mitral and Tricuspid. Each heart valve has two functions:
-To open correctly so blood can enter into or empty from a chamber
-To close properly so blood doesn’t flow back into the area it came from
If one of your heart valves does not work properly, this can affect blood flow. One type of valve disease, called regurgitation, occurs when the leaflets of the valve do not work properly. This allows the blood to flow in the wrong direction. The other type of valve disease occurs when the leaflets of the valve narrow, which makes it more difficult for blood to flow forward. This is called stenosis. Lastly, there can also be atresia, which is when a valve is missing entirely.
