Primary Outcome Measures:

Mean number of monthly migraine days per patient within the 3 months following transcatheter ASD closure. [ Time Frame: 3 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Severity of migraine attacks following ASD closure as evaluated by the intensity of migraine episodes and the Migraine Disability Assessment (MIDAS) questionnaire at 3-month follow-up after ASD closure. [ Time Frame: 3 months ] [ Designated as safety issue: No ]
Incidence of bleeding complications at 3-month follow-up. [ Time Frame: 3 months ] [ Designated as safety issue: Yes ]
Percentage of patients with new-onset migraine attacks. [ Time Frame: 3 months ] [ Designated as safety issue: No ]
Time to first migraine episode. [ Time Frame: 3 months ] [ Designated as safety issue: No ]
Percentage of patients with migraine headaches at 6-month and 1-year follow-up (exploratory only according to local feasibility). [ Time Frame: 1 year ] [ Designated as safety issue: No ]

Arms	Assigned Interventions
Experimental: Aspirin + clopidogrel Aspirin (80 mg/day) + clopidogrel (75 mg/day) for 3 months following ASD closure.	Drug: Clopidogrel 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. Other Name: Clopidogrel (Plavix)
Active Comparator: Aspirin Aspirin (80 mg/day) for 3 months following ASD closure.	Drug: Clopidogrel 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. Other Name: Clopidogrel (Plavix)

Detailed Description:

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.
