Abstract
OBJECTIVES: This study sought to evaluate the long-term effect of transcatheter patent foramen ovale (PFO) closure on migraineurs with and without aura and examine the effect of residual right-to-left shunt. BACKGROUND: Many studies reported improvement in migraine symptoms after PFO closure, yet randomized trials failed to reach its clinical endpoints. METHODS: The study retrospectively analyzed data from 474 patients who underwent transcatheter PFO closure at Massachusetts General Hospital. Patients completed a migraine burden questionnaire at baseline and at follow-up. Migraine severity is reported as migraine frequency (days/month), average duration (min), and migraine burden (days × min/month). Improvement following closure was defined as complete abolishment of symptoms or >50% reduction in migraine burden. RESULTS: A total of 110 migraineurs who underwent PFO closure were included; 77.0% had aura and 23.0% were without aura, and 91.0% had a cryptogenic stroke. During long-term median follow-up of 3.2 (interquartile range: 2.1 to 4.9) years, there was a significant improvement in migraine symptoms in migraineurs with or without aura. Migraine burden was reduced by >50% in 87.0% of patients, and symptoms were completely abolished in 48%. Presence of aura was associated with abolishment of migraine (odds ratio: 4.30; 95% confidence interval: 1.50 to 12.30; p = 0.006). At 6 months after PFO closure, residual right-to-left shunt was present in 26% of patients. Absence of right-to-left shunt was associated with improvement in migraine burden by >50% (odds ratio: 4.60; 95% confidence interval: 1.30 to 16.10; p = 0.017). CONCLUSIONS: Long-term follow-up after transcatheter PFO closure was associated with significant improvement in migraine burden. Aura was a predictor of abolishing symptoms. Absence of residual right-to-left shunt was a predictor of significant reduction in migraine burden.
