What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this single arm, multi-center study is to confirm the safety and effectiveness of the AMPLATZER™ PFO Occluder in the post Approval Setting.

Do I need to stop my current medications for the trial?

The trial information does not specify if you need to stop taking your current medications. However, you must be able to take antiplatelet therapy to participate.

Is the AMPLATZER PFO Occluder generally safe for humans?

The AMPLATZER PFO Occluder has been used in many patients without severe complications, but there have been reports of issues like new-onset atrial fibrillation (irregular heartbeat), residual shunt (incomplete closure), and other device-related problems. Long-term follow-up is recommended to monitor for complications that may appear years after the device is placed. ^{1 2 3 4 5}

How is the AMPLATZER PFO Occluder treatment different from other treatments for patent foramen ovale?

The AMPLATZER PFO Occluder is unique because it is a device specifically designed for percutaneous (through the skin) closure of a patent foramen ovale (a hole in the heart), which helps prevent stroke recurrence by stopping blood clots from passing through the hole. Unlike medication, this treatment involves a minimally invasive procedure to physically close the opening in the heart. ^{1 3 6 7 8}

What data supports the effectiveness of the AMPLATZER PFO Occluder treatment for Patent Foramen Ovale?

Research shows that the AMPLATZER PFO Occluder is effective in closing a patent foramen ovale (a small hole in the heart) and helps prevent stroke recurrence in patients who have had strokes due to paradoxical embolism (a type of blood clot). Studies have demonstrated successful outcomes without severe complications in many patients. ^{1 2 3 6 7}

Are You a Good Fit for This Trial?

This trial is for people aged 18-60 who've had a stroke linked to a heart defect called PFO within the last 547 days. They must be able to take antiplatelet therapy and commit to follow-up visits. It's not for those with uncontrolled high blood pressure, certain heart conditions, severe infections, recent serious heart events, or other identified causes of stroke.

Inclusion Criteria

I have had a stroke caused by a heart condition within the last 18 months.

Exclusion Criteria

I have not had a heart attack or unstable chest pain in the last 6 months.

My heart has a weakened or bulging area.

I have severe narrowing or leaking of my aortic valve.
