What Is The Number Of Mitral Valves In The Heart?

By Adam Pick on September 26, 2007

I just received an email asking, "What is the number of mitral valves in the heart?"

To help answer the question, you will see a human heart diagram (below) that shows a top view of the heart. As you can see there are four heart valves in the heart. The heart valve types are - aortic valve, tricuspid valve, pulmonary valve and... one mitral valve.

So the answer to the question of "What is the number of mitral valves in the heart?" is... one mitral valve.

It is interesting to note that the mitral valve is the only bicuspid valve in the heart. That means that the mitral valve has only two leaflets. As you can see, the other three heart valves each have three leaflets.

However, it is possible for the other valves to have two leaflets. Personally, I had a bicuspid aortic valve which led to my heart valve surgery. Bicuspid valves can trigger heart valve disease including heart valve regurgitation and/or stenosis.

Keep on tickin!
