1 CANOA Trial design: Patients undergoing percutaneous closure of an ASD with the Amplatzer Septal Occluder were randomized to aspirin 80 mg plus clopidogrel 75 mg for 3 months (n = 84) vs. aspirin 80 mg plus placebo for 3 months (n = 87). Results (p = 0.035) Mean number of monthly migraine days per patient within 3 the months following ASD closure: 0.4 in the aspirin plus clopidogrel group vs. 1.4 in the aspirin plus placebo group (p = 0.035) New-onset migraine attacks: 9.5% in the aspirin plus clopidogrel group vs. 21.8% in the aspirin plus placebo group (p = 0.031) 1.4 0.4 Conclusions Among individuals undergoing percutaneous closure of an ASD, aspirin plus clopidogrel was effective at preventing new-onset migraine headache compared with aspirin alone This study confirms the occurrence of new-onset migraine headaches following ASD closure Aspirin plus clopidogrel Aspirin plus placebo Rodés-Cabau J, et al.
