3 or two cusps: The aortic, tricuspid, and pulmonic valves all have three cusps. The mitral valve is the only valve with two cusps.

Atria/venticle: The tricuspid valve is located between the right atria and right ventricle. It is the largest of the 4 valves of the heart. The bicuspid valve is located between the left atria and left ventricle. It is also known as the mitral valve.

What is the function of the bicuspid valve in the heart?

2 doctor answers3 doctors weighed in

You mean malfunction: The aortic valve has 3 parts or leaflets. When its called bicuspid it has only 2 leaflets. This can be congenital or aquired. If two of the cusps fuse over time is called functional bicuspid vs congenital. Either way it creates an un natural flow across the valve and over time damage the valve. Most often the valve will need replace depending on age diagnosed.Most congen bicuspids will need repla.

The same: There is no difference in the amount of work they do -it's just that one has 2 leaflets and the other 3.

Lots: I'm not sure what exactly you're referring to, but the typical valve with two leaflets is the mitral valve. It's usually not called "the bicuspid valve" though. A bicuspid aortic valve is a 2 leaflet aortic valve (should be 3) and is the most common congenital abnormality which can lead to aortic valve leaking or tightness later in life.

Also a bicuspid aortic valve has an increased risk of developing ascending aortic aneurysms. If you have a bicuspid aortic valve your cardiologist will follow the valve as well as the diameter of the ascendding aorta.

Both.: I suspect most would say the bicuspid as the pressures are greater, but i kind of like them both. The tricuspid has one more leaf doesn't that count for something?
