Migraine, mitral valve prolapse and platelet function in the pediatric age group

The authors evaluated 58 pediatric patients (39 females) suffering from various kinds of migraine in order to assess the prevalence of mitral valve prolapse, using echocardiography, and platelet function, using standard platelet aggregation tests. The patients were grouped as follows: 14 subjects with muscle contraction headache, 9 subjects with common migraine, 13 subjects with classic migraine, 22 subjects with complicated migraine.
