Abstract

Transcatheter closure of PFO or ASD results in complete resolution of MHA in 60% of patients (75% of patients with migraine and aura) and improvement in symptoms in 40% of the remaining patients. Interatrial communications may play a role in the etiology of MHA either through paradoxic embolism or humoral factors that escape degradation in bypassing the pulmonary circulation. A randomized trial is needed to determine whether transcatheter closure of interatrial shunts is an effective treatment for MHA.
