title: Considerations on the pathogenesis of mitral valve prolapse.
abstract: Forty patients (11 males and 29 females) with mitral valve prolapse (MVP) were investigated clinically as well as by echocardiographic, phonomechanocardiographic, radiologic, electroencephalographic, electromyographic, psychologic and biologic examinations. Hypomagnesemia was found statistically significant and is assumed to have an important etiopathogenic role particularly in causing the rhythm and neuropsychic disturbances in MVP. A case in which MVP appeared after a prolonged treatment with prednisone, is presented.
