Which heart valve works harder, the bicuspid or tricuspid?

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.
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?

Can someone survive with torn heart valve?

Usually no. Probably the most common "torn heart valve" is the mitral valve with a ruptured support structure. Frequently when a patient has a ruptured mitral valve apparatus, they are in dire need of mitral valve repair and do not do well in its absence. Rarely however, the patient will be ok for some time, but since mitral insufficiency can be asymptomatic until it's too late, i would not wait too long. Read more...
Sure... for a while. The issue is how torn, and how much leakage is coming along for the ride. In an ICU setting, we can usually keep things under control even when it's severe until we can do surgery. Less severe problems may not even need treatment (huge portions of the population have trivial amounts of leakage of one or more valves and this should not prompt concern). Read more...
