Clopidogrel For the Prevention of New Onset Migraine Headache Following Transcatheter Closure of Atrial Septal Defects
The objective is to evaluate the incidence and severity of new-onset migraine headache episodes following transcatheter ASD closure in patients treated with aspirin alone compared to those on aspirin + clopidogrel therapy as antithrombotic treatment after the procedure.
This is a prospective, randomized, double blind, multicenter study, including patients with no previous history of migraine attacks who have been diagnosed with an ASD and for whom transcatheter ASD closure has been clinically indicated. Patients will be randomized either to aspirin (80 mg/day) or aspirin (80 mg/day) + clopidogrel (75 mg/day) for 3 months following ASD closure. The occurrence and severity of migraine headaches will be evaluated by a neurologist using a structured headache questionnaire at 1 month and 3 months following ASD closure. An additional 6 month and 1 year follow-up evaluation will be exploratory according to local feasibility.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Prevention

Medical and Biotech [MESH] Definitions
A class of disabling primary headache disorders, characterized by recurrent unilateral pulsatile headaches. The two major subtypes are common migraine (without aura) and classic migraine (with aura or neurological symptoms). (International Classification of Headache Disorders, 2nd ed. Cephalalgia 2004: suppl 1)
A subtype of migraine disorder, characterized by recurrent attacks of reversible neurological symptoms (aura) that precede or accompany the headache. Aura may include a combination of sensory disturbances, such as blurred VISION; HALLUCINATIONS; VERTIGO; NUMBNESS; and difficulty in concentrating and speaking. Aura is usually followed by features of the COMMON MIGRAINE, such as PHOTOPHOBIA; PHONOPHOBIA; and NAUSEA. (International Classification of Headache Disorders, 2nd ed. Cephalalgia 2004: suppl 1)
