The device is made of two discs that make contact with the tissue walls on both sides of the opening and, when engaged, come together to block the passage of blood between the atria. It was recently approved by the FDA for ASD, as well as for patent foramen ovale closures as a way of reducing the chances of ischemic stroke.
The implant can be used to treat openings between 8 mm and 35 mm in diameter, including those without a retro-aortic rim. It lets native tissue grow into itself, further facilitating healing. “Larger defects typically have a greater risk for complications, like pulmonary hypertension, right heart enlargement, or atrial fibrillation. But previously, Europe didn’t have access to the GORE CARDIOFORM ASD Occluder for this range of defects,” said Matthew Gillespie, M.D., Children’s Hospital of Philadelphia, co-principal investigator of the ASSURED Clinical Study, in a Gore press release. “CE Mark makes this soft, conformable device available for the minimally invasive treatment of a broader range of ASDs.”
