Minor abnormalities in valve shape are relatively common. For example, an estimated 10 percent of normal individuals ages 14–30 have some degree of mitral valve prolapse where the cusps of the mitral valves do not close properly. The problem may stem from abnormal chordae tendineae or malfunctioning papillary muscles. Because the valve does not work perfectly, some regurgitation takes place when the ventricle contracts. Most individuals with mitral valve prolapse have no symptoms. They live normal, healthy lives unaware of any circulatory malfunction. Serious valve problems are very dangerous because they reduce pumping efficiency. If valve function deteriorates such that the heart cannot maintain adequate circulatory flow, symptoms of valvular heart disease appear. Congenital defects may be responsible, but in many cases the condition develops following carditis, an inflammation of the heart. In severe cases, the only option may be to replace the damaged valve with a prosthetic one. Where is the mitral valve found?
