Feasibility of Sentinel Cerebral Embolic Protection Device Deployment During Transfemoral Transcatheter Aortic Valve Replacement.

Cerebral embolic protection has emerged as a preventive measure for procedural stroke in transcatheter aortic valve replacement (TAVR).1 The Sentinel System (Boston Scientific Corp. Boston, Massachusetts), a 2-filter debris-capturing system, has been the only commercially available protection device in the United States since its approval by the Food and Drug Administration in 2017. In the Sentinel trial, the largest randomized trial (n = 363) so far, the device was successfully deployed in 94.7% of patients.
