Active Comparator: Standard or Care - Medical Management
Medical treatment with Aspirin alone, Coumadin alone, Clopidogrel alone, or Aspirin combined with dipyridamole.
Other: Standard of Care - Medical Management
Medical management - aspirin alone, Coumadin alone, Clopidogrel alone, aspirin combined with dipyridamole
- Composite of Recurrent Nonfatal Ischemic Stroke, Fatal Ischemic Stroke, or Early Death After Randomization [ Time Frame: Trial enrollment was stopped once 25 unique subjects were mutually adjudicated by the CEC and DSMB as having experienced a primary endpoint event. This occurred on December 20, 2011. The mean follow-up time was 2.6 years. ]
Nonfatal stroke is defined as: focal neurological deficit presumed to be due to focal ischemia, and either 1) symptoms persisting 24 hours or greater, or 2) symptoms persisting less than 24 hours but associated with MR or CT imaging findings of a new, neuroanatomically relevent, cergral infarct.
Post-randomization death is defined as: in the MM group as all-cause mortality within 45 days after randomization, and in the device group as all-cause mortality 30 days after implant or 45 days after randomizaiton, whichever occurs last.
- Rate of Complete PFO Closure (Assessed by TEE Bubble Study) at the 6-month Follow-up in the Device Group [ Time Frame: 6 months ]
