INDUSTRY-LEADING DEVICE. DESIGNED SPECIFICALLY FOR PFO CLOSURE.

A Landmark Device. And a Turning Point for PFO Closure.

The Amplatzer™ PFO Occluder set the standard, pioneering treatment with a device developed specifically for PFO closure. It’s the leading PFO closure device to date, with over 130,000 devices implanted worldwide.4

Amplatzer PFO Occluder

Four published clinical trials provide conclusive evidence of the superiority of Patent Foramen Ovale (PFO) closure in reducing the risk of recurrent stroke compared with medical management.1-4 The RESPECT trial, the largest trial with the most extensive patient follow-up, demonstrated an excellent safety profile while significantly reducing the risk of recurrent stroke:1

Highlights from the RESPECT trial1

  • The most extensive patient follow-up with 5,810 patient years of data
  • Zero device erosions, thrombus, or embolization events
  • 94.2% effective closure rates at 6 months
  • Only trial to include patients on anticoagulation therapy

Comments from RESPECT Trial Principal Investigator

Jeffrey Saver, MD discusses the data supporting the benefits of PFO closure.

RESPECT Trial: A Turning Point in PFO Closure

The RESPECT trial is notable for demonstrating that the Amplatzer PFO Occluder is more beneficial than medical therapy alone in preventing recurrent stroke.1

The findings also revealed a reduction in the risk of recurrent stroke of unknown cause with the use of the Amplatzer PFO Occluder:1

Relative Risk Reduction for Recurrent Stroke of Unknown Cause: 62%

Amplatzer PFO relative risk reduction for recurrent cryptogenic stroke

Relative Risk Reduction for any Recurrent Ischemic Stroke: 45%

Amplatzer PFO relative risk reduction for any recurrent ishemic stroke

The trial analysis reveals that the device reduced recurrent ischemic stroke by eliminating a conduit through which venous source emboli can travel to the brain.

Low Rate of Serious Adverse Events

RESPECT data further revealed low rates of serious adverse events:1

  • 0% Device Embolization
  • 0% Device Erosion
  • 0% Device Thrombus

Excellent Procedural Results

In the RESPECT Trial, the device demonstrated high rates of technical and procedural success and achieved excellent effective closure with highly stringent criteria.

  • 99.1% Technical Success
  • 96.1% Procedural Success
  • 94.2% Effective closure at 6 months (n <= 9 bubbles)

Prioritizing Prevention

Referring physicians, and particularly neurologists who provide the primary point of care for patients who've had an ischemic stroke, may consider these factors in treatment planning:

  • Is there a known cause for the stroke?
    Rule out known causes
  • Is the patient a good candidate for alternative therapy?
    Consider the patient’s age and medical history
  • Is there a possibility of a PFO?
    Determine the likelihood of paradoxical embolism

A cardiologist can then determine whether a PFO is present and can help define treatment options.

Leadership in PFO Closure Treatment

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.
