Objectives: This single-center, observational, prospective study evaluated the impact of patent foramen ovale (PFO) closure on migraine attacks over time. Background: PFO closure may reduce the frequency and severity of migraine headaches in patients with significant right-to-left shunts. Methods: Between May 2000 and September 2009, 305 consecutive patients (mean age, 43 ± 12 years; 54.5% women) with a prior embolic cerebrovascular event underwent PFO closure with the Amplatzer PFO occluder for recurrence prevention. All patients had right-to-left shunts; the shunts were associated with migraine symptoms in 77 (25%), either alone (n = 64, 83%) or with aura (n = 13, 17%). Septal aneurysm was present in 15 (19.5%) migraine patients, and 43 (56%) had a previous transient brain ischemic attack. All migraine patients had a computed tomography scan or magnetic resonance imaging, indicating a previous brain ischemic lesion. All 305 patients underwent transthoracic echocardiography with clinical follow-up at 24 hr, at 3, 6, and 12 months, and then yearly. Results: An acute migraine attack occurred 24-48 hr after PFO closure in 28 (36.4%) of 77 patients. There was a significant reduction (>50%) in the number and intensity of attacks in 46 (60.5%) of 77 patients at the 3-month follow-up. At the 12-month follow-up, migraine had ceased in 23 (46%) patients, and 20 (40%) had a reduction in the migraine recurrence rate and disabling symptoms. These results were maintained at follow-up (mean, 28 ± 27 months). There was overall improvement in migraine in 89% of the treated patients. Conclusions: Percutaneous PFO closure in migraineurs may provide beneficial mid-term and long-term results, with significant reduction in the intensity and frequency of headache symptoms. © 2010 Wiley-Liss, Inc.
