Summary
This trial is testing three devices for closing a PFO, a hole in the heart, to see which is best at preventing recurrent embolic stroke with the fewest serious side effects.
Who is the study for?
This trial is for adults aged 18 and over who've had a stroke of unknown cause (cryptogenic) linked to a heart condition called Patent Foramen Ovale (PFO). Participants must be able to stop anticoagulation meds, have a life expectancy over 2 years, and not have other conditions causing strokes or serious heart issues.
What is being tested?
The study compares the Occlutech Flex II PFO Occluder with standard devices like the AMPLATZER™ PFO Occluder in preventing strokes by closing the PFO. It looks at how well they work and their safety by tracking Serious Adverse Events related to them.
What are the potential side effects?
Potential side effects from using these occlusion devices may include discomfort at the implant site, bleeding, blood vessel damage, irregular heartbeat, or allergic reactions to device materials.
