Mitral valve prolapse.

Abstract Mitral valve prolapse is the most common heart disease seen in college and university health services. It underlies most arrhythmia and many chest pain complaints. Auscultatory findings vary; only 60% have the click, only 48% have the murmur, and in half of those with murmur, it was heard better at the upper-left sternal border than at the apex. In 15%, neither click nor murmur was heard. Only two patients had major arrhythmia. Endocarditis prophylaxis is indicated. Activity and exercise restrictions are usually unnecessary.
