The REDUCE Study is the only PFO U.S. IDE study to meet its primary endpoint in the primary intent-to-treat analysis. Results showed a statistically significant, 77 percent, reduction in recurrent ischemic stroke in patients who underwent PFO closure with a Gore device in conjunction with antiplatelet therapy, versus those who underwent antiplatelet therapy alone, after an average of 3.4 years of follow-up. The study also met its other primary endpoint of reduction of new brain infarct, inclusive of clinically evident and clinically silent brain infarct, through PFO closure, yielding a 49 percent relative risk reduction.

"With the FDA approval of the GORE CARDIOFORM Septal Occluder for PFO closure, we can now provide physicians with one device that can be used for both ASDs and PFOs," said David Abeyta, Leader of the Gore Medical Products Division. "The value of closing PFOs has historically been debated, mainly due to a lack of sufficient data. We are enthusiastic that our positive REDUCE Study results allowed us to obtain an expanded FDA indication for this device and strongly believe the data show this is a prevention strategy for reducing the risk of recurrent ischemic stroke in patients with a PFO."


The catheter-delivered GORE CARDIOFORM Septal Occluder* leverages Gore's more than 15 years of experience in endovascular structural heart devices and more than 35,000 occluder implants worldwide. It comprises two independent conformable discs that span and cover the heart's anatomy to close defects. Gore's proprietary ePTFE film covers the minimal wire frame, which provides optimal apposition to surrounding anatomy and enables rapid tissue ingrowth for immediate closure and lasting long-term performance.

ABOUT STROKE AND PFO
In the U.S., stroke is the leading preventable cause of long-term severe disability and the fifth-leading cause of death. One third of ischemic strokes are cryptogenic, or due to unknown cause. Most people with a PFO — a hole occurring in the upper wall between the left and right atria of the heart — do not experience any issues when blood flows from one atrium to the other; however, serious problems such as stroke can arise if a blood clot passes from the right to left atria through a PFO and then to the brain. Studies have shown that PFO can be found in up to 40 percent to 50 percent of patients who have had a cryptogenic stroke.
