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?

Do you care?: Who cares? All valves have to work or you're dead.

Four heart valves: All 4 of your heart valves have three cusps. If you have a heart valve with 2 cusps that is a common congenital anomaly. A bicusp heart valve does not perform as well as a regular three cusp valve over a lifetime. Occasionally the bicusp valve will need repair or replace. The four valves are named; pulmonary, aortic, tricuspid and mitral. Be well.

3 or two cusps: The aortic, tricuspid, and pulmonic valves all have three cusps. The mitral valve is the only valve with two cusps.
A 24-year-old member asked:

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

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.
