Counterintuitively, use of cerebral embolic protection failed to reduce the incidence of stroke in the 72 hours following a transcatheter aortic valve replacement or implantation found a late-breaking clinical trial presented at ACC.25, the American College of Cardiology’s annual scientific session held March 29-31 in Chicago and simultaneously published in the New England Journal of Medicine.

Protembis GmbH received €20 million (US$21.66 million) in financing from the European Investment Bank to develop its cerebral embolic protection system, Protembo. The intra-aortic filter device deflects embolic material away from arteries leading to the brain during left-sided heart procedures including transcatheter aortic valve replacement.

Keystone Heart Ltd. had the unusual experience of being the sponsor of a rare class II device appearance before an FDA advisory committee, which considered whether the company’s Triguard 3 device was substantially equivalent (SE) to a predicate device. However, the company’s bid for an SE result was unsuccessful, likely leaving Keystone with a considerable additional regulatory lift before the company can get to market.

Keystone Heart Ltd., of Caesarea, Israel and Tampa, Fla., scored a win in Europe after obtaining the CE mark for the Triguard 3 cerebral embolic protection (CEP) device. It is designed to minimize the risk of cerebral damage by deflecting embolic debris away from cerebral circulation during transcatheter aortic valve implantation (TAVI) and other transcatheter heart procedures. According to the company, the device is the only product with a CE mark designed to cover and protect all three major cerebral aortic arch vessels.
