NICE has been notified about this procedure and it is part of its work programme. The Interventional Procedures Advisory Committee (IPAC) will consider this procedure and NICE will issue an interventional procedures consultation document about its safety and efficacy for 4 weeks’ public consultation. IPAC will then review the consultation document in the light of comments received and produce a final interventional procedures document, which will be considered by NICE before guidance is issued to the NHS in England, Wales, Scotland and Northern Ireland.

Description Percutaneous insertion of a cerebral protection device aims to prevent debris dislodged during TAVI from passing into the cerebral circulation. The aim is to reduce the risk of a transient ischaemic attack or stroke. During the TAVI procedure, before the valve is inserted, a cerebral protection device is inserted percutaneously through the radial or femoral artery and placed into the aortic arch. It is deployed to protect the ostia of the brachiocephalic artery and the left common carotid artery, and may also protect the left subclavian artery (depending on the type of device used). It works either by filtering dislodged debris from the blood, or by deflecting dislodged debris away from the cerebral circulation to the systemic circulation. The device is removed at the end of the TAVI procedure. The evidence review identified 3 types of cerebral protection devices. One is a deflector system that covers all 3 main branches of the aortic arch. The 2 other types cover the brachiocephalic trunk and the left common carotid artery; 1 is a filter system, the other is a deflector system.
