Transcatheter Aortic Valve Replacement (TAVR)

Recent studies have shown that almost 1 in 10 TAVR patients show overt signs of ischemic brain injury as a result of TAVR procedure.1 The Sentinel Cerebral Protection System (CPS) has been shown to reduce strokes by 63% in the first 72 hours after TAVR, when most strokes occur2 and is corroborated by a reduction in TAVR stroke, and stroke or mortality by 70%.3 In clinical studies, Sentinel CPS removed visible debris headed towards the brain in 99% of TAVR cases,1 regardless of replacement valve used and with virtually no added risk.

Simple and Safe

The Sentinel has been found safe and compatible to use with all commercially-available TAVR valves.1 It is simple to use, and has demonstrated 99% deployment success in a median deployment time of four minutes.1

Sentinel CPS is securely positioned away from the aortic arch, avoiding extended contact with potentially calcified tissue, minimizing interference with TAVR catheters, and enabling physicians to put all their focus on the TAVR procedure itself.
