Efficacy of Sentinel Cerebral Embolic Protection Device in Transcatheter Aortic Valve Replacement: A Meta-Analysis of Randomized Controlled Trials and Propensity Score-Matched Studies

Abstract

Transcatheter aortic valve replacement (TAVR) is frequently associated with stroke due to debris embolization. Although the risk of stroke with newer-generation devices is lower, stroke still represents a significant cause of mortality and morbidity post-TAVR. The Sentinel cerebral embolic protection device (CEPD) is a dual-embolic filter device designed to capture debris dislodged during TAVR. A systematic literature search was performed on the major bibliographic databases to retrieve studies that compared TAVR with and without Sentinel CEPD. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using the DerSimonian–Laird random-effects model, with a P value of <0.05 considered statistically significant. This meta-analysis included 6 studies with 25,130 patients undergoing TAVR (12,608: Sentinel CEPD; 12,522: without Sentinel CEPD). The use of the Sentinel CEPD in TAVR was associated with a statistically significant lower risk of acute kidney injury (OR: 0.89; 95% CI: 0.81–0.97; P = 0.01]. The use of Sentinel CEPD in TAVR was associated with a statistically insignificant trend toward a reduction in stroke (OR: 0.80; 95% CI: 0.58–1.10; P = 0.18), all-cause mortality (OR: 0.74; 95% CI: 0.51–1.07; P = 0.11), and major vascular complications (OR: 0.74; 95% CI: 0.46–1.19; P = 0.21). The use of Sentinel CEPD in patients undergoing TAVR does not lead to a statistically significant reduction in stroke, all-cause mortality, or major vascular complications; however, the risk of acute kidney injury is lower. Further randomized studies are warranted to confirm these findings.
