[Clinicofunctional characteristics of primary mitral prolapse in adolescents].

To investigate clinicofunctional features of primary mitral prolapse (PMP) in adolescents, 60 patients were examined (42 adolescent girls and 18 adolescent boys aged 14 to 20 years). Control group consisted of 15 healthy adolescents of the same age. PMP in adolescents was characterized by marked manifestations of connective tissue dysplasia (CTD) and vegetative dysfunction (VD). As shown by echocardiography, 71.7% patients had bilateral prolapse with mitral regurgitation of degree I and II. 18.7% examinees with pronounced CTD and VD had asymptomatic variant of PMP.
