Comparing PFO Outcomes of the Occlutech Flex II PFO Occluder to Standard of Care PFO Occlusion

To be part of this study, you would need to have a PFO and have experienced a stroke for which doctors haven't found another obvious cause. Doctors would confirm the PFO using a special heart scan (called a Transoesophageal Echo or TEE). The stroke would be confirmed if you had sudden brain symptoms that lasted a while, or if scans showed a new area of damage in your brain.

There are also some reasons why you wouldn't be able to join. For example, if you're under 18, or if you've had a heart attack or chest pain recently (within 6 months). Certain serious heart problems, like weak heart pumping or problems with your heart valves, would also mean you couldn't take part. If your blood pressure or diabetes is not under control, or if you have other serious health issues that might make participating difficult or risky, you'd also be excluded.

Finally, if you have other clear reasons for your stroke, such as an irregular heartbeat (atrial fibrillation), blood clots in your heart, certain severe narrowing of blood vessels, or if you couldn't take commonly prescribed blood-thinning medicines, then this study might not be suitable for you.

The detailed information about what taking part involves hasn't been provided in this summary, so we can't give specific details about the number of visits, specific assessments, or medication schedule. Generally, for studies like this involving a device, you would likely have a PFO closure procedure. This would be followed by several check-up appointments over a period, which might include heart scans and discussions with the study team, to monitor the device and your health. Any medications would be precisely explained, and you would be told the total expected duration of your involvement in the study.
