Product Value—GORE® CARDIOFORM Septal Occluder

Provides clinical and economic value through groundbreaking outcomes

Image of GORE® CARDIOFORM Septal Occluder deviceGORE® CARDIOFORM Septal Occluder is a device used for transcatheter closure of patent foramen ovale (PFO) to reduce the risk of recurrent stroke.* 

A PFO is a hole in the heart that didn't close the way it should after birth — Occurs in approximately 1:4 individuals.1 In most people, a PFO creates no symptoms and requires no treatment.  However, in a small minority, a PFO may permit blood clots to pass from the right side of the heart to the left, possibly leading to a stroke.  

The impact of a recurrent stroke can not only be devastating but also costly. Nearly 30 percent of all strokes are recurrent events2 and the financial impact for the estimated average mean lifetime cost of ischemic stroke for a single patient is equal to $152,507.3

Five-year results of the REDUCE Study further supports the use of GORE® CARDIOFORM Septal Occluder in long-term recurrent stroke prevention.4

Patients who underwent PFO closure reported significantly higher physical vitality, general health, mental health and social functioning than non-closure patients.5-7 SF-36 assesses quality of life by measuring physical and mental health scores across eight dimensions (36 questions).

According to AHA, the mean lifetime cost of ischemic stroke in a single patient in 2014 was approximately $140,048 in the United States. Cumulative rate of inflation from 2014 to 2020 is .65%. Estimated mean lifetime cost in 2020 = $152,507.

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
