Some types of migraine are associated with ischemic stroke. Although a right-to-left communication is linked with ischemic stroke, a causal relationship between migraine and right-to-left communication remains unclear. Furthermore, the efficacy of transcatheter closure of atrial communication on migraine is controversial. We aimed to evaluate the influence of transcatheter closure of atrial communication on migraine in patients with ischemic stroke. Thirty-eight consecutive patients with ischemic stroke who underwent transcatheter closure of atrial communication were enrolled. The prevalence, frequency, and severity of migraine were prospectively evaluated at baseline, 3 months, and >6 months after the procedure. Changes in migraine after the procedure were classified according to the frequency and severity of migraine: disappeared, improved, no-change, and worsening. Nineteen (50 %) of 38 patients suffered from migraine at baseline. No significant differences were observed in age, comorbidities, defect diameter, and atrial septal aneurysm between patients with migraine and patients without migraine. Among the 19 patients with migraine, migraine disappeared in 10 (53 %) patients and improved in 8 (42 %) patients at 3 months after transcatheter closure of atrial communication. At mean follow-up of 38 ± 28 months after the procedure, migraine disappeared in 12 (63 %) patients and improved in five (26 %) patients. No patients experienced worsening of migraine during the follow-up period. New-onset migraine was not observed in patients without migraine. Migraine is complicated in a half of patients with ischemic stroke related to atrial communication. Such migraine may disappear or improve after transcatheter closure of atrial communication.
