Gore REDUCE Clinical Study five-year results demonstrate PFO closure provides safe long-term prevention of recurrent stroke.
The REDUCE Study is the only U.S. IDE trial that achieved its primary end point and showed the largest reduction in recurrent ischemic stroke*,1 in all PFO shunt sizes over medical therapy alone.
Clear data. Confident stroke prevention.
ROBUST TRIAL DESIGN
Groundbreaking 77% relative reduction in recurrent stroke for cryptogenic stroke patients*,1
Rapid demonstration of statistically significant stroke reduction:
Met primary endpoint in the intention-to-treat analysis*,1 with an average follow-up of 3.4 years
Met primary end point in ALL PFO anatomies and ALL shunt sizes*,1
Number needed to treat: Only 28 patients treated to prevent one stroke at 24 months1
The REDUCE Study was the first U.S. Investigational Device Exemption (IDE) study of a PFO closure device to show a statistically significant reduction in stroke recurrence in the primary intent-to-treat analysis.

* The REDUCE study determined safety and efficacy of patent foramen ovale (PFO) closure with the GORE® CARDIOFORM Septal Occluder or GORE® HELEX® Septal Occluder plus antiplatelet medical management compared to antiplatelet medical management alone in patients with a PFO and history of cryptogenic stroke. All PFO anatomies were incorporated into this study within indicated sizing parameters of the Instructions for Use.
** Cryptogenic diagnosed as: No stenosis > 50 percent or ulcerated plaque in relevant intra- or extra-cranial vessels, no atrial fibrillation or high-risk source of cardioembolism, non-lacunar (based on neuroimaging), no evidence of hypercoagulable disorder, no other known cause of stroke.
† PFO confirmed by transesophageal echocardiography (TEE / TOE) with bubble study demonstrating right-to-left shunt at rest or during Valsalva maneuver. Patients with PFO eligible regardless of shunt size or presence of atrial septal aneurysm.
‡ There was no statistically significant difference in the rate of serious adverse events (SAE) between the closure and medical groups. There was a significantly higher rate of atrial fibrillation or flutter in the closure group (6.6 percent versus 0.4 percent) but the majority was non-serious (66 percent), peri-procedural (69 percent had onset within 30 days of the closure procedure), and had rapid resolution (59 percent with resolution within two weeks of onset). Average of 3.4 years follow-up.
§ Device and procedure-related SAEs occurred in 1.4 and 2.5 percent, respectively, of closure patients.
II GORE® CARDIOFORM Septal Occluder effective closure rate results in device group subjects who received a study device. Effective closure defined as freedom from large shunt > 25 bubbles as detected by transthoracic echocardiography adjudicated by echo core lab.
