Patent Foramen Ovale Closure or Medical Therapy After Stroke - RESPECT Trial

Not Applicable
Completed
Conditions
Cryptogenic Stroke
Interventions
Other: Standard of Care - Medical Management
Device: AMPLATZER PFO Occluder
Registration Number
NCT00465270
Lead Sponsor
Abbott Medical Devices
Brief Summary

The purpose of this study is to investigate whether percutaneous Patent Foramen Ovale (PFO) closure, using the AMPLATZER PFO Occluder, is superior to current standard of care medical treatment in the prevention of recurrent embolic stroke.

Detailed Description

The AMPLATZER PFO Occluder is a percutaneous, transcatheter occlusion device intended for the non-surgical closure of patent foramen ovale in subjects who have had a cryptogenic stroke due to presumed paradoxical embolism within the last 270 days.

Primary Outcome Measures
NameTimeMethod
Composite of Recurrent Nonfatal Ischemic Stroke, Fatal Ischemic Stroke, or Early Death After RandomizationTrial 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.
