What is Amplatzer PFO occluder made of?

What is Amplatzer PFO occluder made of?

The AMPLATZER™ PFO Occluder is a self-expandable, double-disc device made from a Nitinol wire mesh. The 2 discs are linked together by a short connecting waist. In order to increase its closing ability, the discs contain thin polyester fabric. The polyester fabric is securely sewn to each disc by a polyester thread.

What is a PFO occluder?

Device Description The AMPLATZER PFO Occluder is a self-expandable, double disc device made from a Nitinol wire mesh. The two discs are linked together by a short, connecting waist, allowing free motion of each disc. In order to increase its closing ability, the discs contain thin polyester fabric.

How does Amplatzer septal occluder work?

Amplatzer™ SEPTAL Occluders These double-disc occluders are comprised of nitinol mesh and polyester material. They are designed to securely appose the septal wall on each side of the defect and create a platform for tissue in-growth after implantation.

What is aortic erosion?

Aortic erosion is a serious complication that usually occurs shortly after Amplazter Septal Occluder (ASO) implantation for atrial septal defect (ASD).

What is the recovery time for PFO closure?

This is very common about 2 weeks to 6 weeks post closure; usually treatment is NOT required. Prior to discharge, you will be given instructions and a person to contact with questions or concerns.

Does PFO closure prevent stroke?

Both meta-analyses showed that PFO closure prevents recurrent stroke but increases the incidence of AF as compared to medical treatment. PFO closure was associated with a stroke risk reduction of 3.1–3.3% [62, 63] and new-onset AF/flutter risk increment of 3.3% [62].

When should a PFO be fixed?

You usually do not need treatment if you have no risk factors for stroke or any history of traveling blood clots. Your healthcare provider may want to treat your PFO if you have had problems, such as strokes from these traveling blood clots.

What is the recovery time for a PFO closure?

Is Gore Cardioform septal occluder MRI safe?

No. Your Gore implant will not be affected by medical imaging methods, household appliances, or security sensors. The clarity of medical images, such as MRI, may be slightly reduced because of the GORE® CARDIOFORM Septal Occluder wire frame.

Is the Amplatzer septal occluder MRI safe?

Magnetic resonance imaging (MRI) scans are generally acceptable, and your AMPLATZER PFO Occluder is compatible with imaging when using a 3-tesla MRI.

What can I expect after ASD closure?

It takes about 6 weeks for a chest incision to heal. After that, if there are no problems and the doctor say it’s OK, your child should be fully recovered and able to return to normal activities. Heart surgery does leave a permanent scar on the chest.

What is ASD closure?

An atrial septal defect is a hole between the two upper chambers of the heart. To close the hole, the doctor will place a special device in your child’s heart by catheterization. If the hole is too big to close with the device or in the wrong position, the hole will be closed with surgery.

What is the risk of erosion of an Amplatzer?

Erosion is a rare but serious risk of closure of ASDs and PFOs using Amplatzer septal occluder devices. The rate of erosion of Amplatzer ASD and PFO occluder devices is estimated to be approximately 0.1% but carries a high risk of mortality.

Where does erosion of an Amplatzer Septal Occluder occur?

Erosion of Amplatzer septal occluder device after closure of secundum atrial septal defects: review of registry of complications and recommendations to minimize future risk. Erosion most often occurs at the anterosuperior wall of the right or left atrium, resulting in pericardial effusion, frequently with cardiac tamponade.

What makes the Amplatzer PFO occluder so effective?

The Amplatzer PFO Occluder’s unique design is a primary reason for its safety and efficacy. In addition, the occluder’s capability to be fully recaptured and fully repositioned allows physicians to confirm proper placement prior to final release of the device.

What are the risks of septal occlusion device erosion?

Septal occlusion device erosion remains a major issue among the risks imposed by device closure of an ASD. More data are needed to better understand its true causes and possible solutions. Transcatheter device closure of atrial septal defects (ASDs) is a minimally invasive technique that offers an alternative to conventional surgical repair.
