Why does bacterial endocarditis usually attack the mitral valve and not the others?

Endocarditis: Bacterial infection of the heart valves is rare. Any valve can become infected, but usually an abnormal or damaged valve is the most susceptible. Mitral valve prolapse is one of the more common valve abnormalities and may be more likely to get infection.

It doesn't: Endocarditis usually occurs on a previously abnormal or damaged valve. It may seem that the mitral valve has a higher incidence but it really may occur on any valve.

Not so: Endocarditis may also affect aortic and tricuspid valves as well as prosthetic valves.

Not true: Ie can affect any valve and often involves the aortic valve. Those who use IV drugs are more prone to have infection of their tricuspid valve.
