Trends in Cerebral Embolic Protection Device Use and Association With Stroke Following Transcatheter Aortic Valve Implantation.

Abstract

Stroke remains a serious complication of transcatheter aortic valve implantation (TAVI). Prior studies examining the association between cerebral embolic protection device (CEPD) use and stroke following TAVI have produced conflicting results. We used the Nationwide Readmissions Databases to identify all percutaneous (non-transapical) TAVIs performed in the US from July, 2017 to December, 2018. Overlap propensity score weighted logistic regression models were used to determine the association between CEPD use and outcomes. The primary outcome was in-hospital stroke or transient ischemic attack (TIA). Among 50,000 percutaneous TAVIs (weighted national estimate: 88,886 [SE: 2,819]), CEPD was used in 2,433 (weighted national estimate: 3,497 [SE: 857]). Nationally, the utilization rate of CEPD was 3.9% (SE: 0.9%) of all TAVIs during the overall study period, which increased from 0.8% (SE: 0.4%) in 2017Q3 to 7.6% (SE: 1.6%) in 2018Q4 (p<0.001). The proportion of hospitals using CEPD increased from 2.3% in 2017Q3 to 14.7% in 2018Q4 (p<0.001). There were no significant differences in rates of in-hospital stroke/TIA in TAVIs with versus without CEPD (2.6% vs 2.2%; unadjusted OR [95% CI] 1.18 [0.98-1.52]; overlap propensity score weighted OR [95% CI] 1.19 [0.81-1.75]). CEPD use was not associated with statistically significant lower rates of in-hospital stroke, ischemic stroke, hemorrhagic stroke, TIA, all-cause mortality, or discharge to skilled nursing facility. In conclusion, the rates of CEPD utilization and proportion of TAVI hospitals using CEPD increased during the study period. The use of CEPD during TAVI was not associated with statistically significant lower rates of in-hospital stroke, TIA, or mortality.
