Abstract

BACKGROUND: Cerebral embolic protection devices (EPDs) were developed to mitigate the risk of stroke during transcatheter aortic valve replacement (TAVR), but their benefit remains unproven. In the PROTECTED-TAVR trial (Stroke Protection With Sentinel During Transcatheter), EPD use did not reduce periprocedural stroke (primary study outcome) but led to a 62% reduction in the secondary end point of disabling stroke. Given these results, the impact of EPDs during TAVR remains unclear. METHODS: We used STS/ACC TVT registry data to examine the association between EPD use and a proxy for disabling stroke among transfemoral TAVR patients between January 2018 and June 2023. The primary outcome was in-hospital disabling stroke--defined as stroke associated with either in-hospital death or discharge to a nonhome location. We evaluated the association between EPD use and disabling stroke using instrumental variable analysis with a site-level preference for EPD use as the instrument--a quasi-experimental approach that can support causal inference. In addition, we performed a propensity score--based comparison using overlap weighting as a secondary analysis. RESULTS: The study population consisted of 414 649 patients of whom 53 389 (12.9%) received an EPD. The unadjusted rate of in-hospital disabling stroke was 0.7% among the EPD group and 0.9% in the no-EPD group. EPD use was associated with a reduction in disabling stroke in both instrumental variable analysis (relative risk, 0.87 [95% CI, 0.73--1.00]) and propensity-weighted analysis (odds ratio, 0.79 [95% CI, 0.70--0.90]) but was not associated with a reduction in nondisabling stroke. In subgroup analyses, the benefit of EPD was greater among those with versus without prior stroke (Pinteraction<0.05 for both instrumental variable and propensity-weighted analyses). CONCLUSIONS: In the largest study to date, among patients undergoing TAVR, EPD use was associated with a small, borderline significant reduction in stroke associated with death or discharge to a nonhome location (a proxy for disabling stroke) that is likely to be causal in nature. Taken together with previous mechanistic and clinical studies, these findings provide credible evidence that EPDs benefit patients undergoing TAVR.

46. Hospital Characteristics and Early Enrollment Trends in the American College of Cardiology Voluntary Public Reporting Program

Abstract

Importance: Limited data exist regarding the characteristics of hospitals that do and do not participate in voluntary public reporting programs. Objective: To describe hospital characteristics and trends associated with early participation in the American College of Cardiology (ACC) voluntary reporting program for cardiac catheterization-percutaneous coronary intervention (CathPCI) and implantable cardioverter-defibrillator (ICD) registries. Design, Setting, and Participants: This cross-sectional study analyzed enrollment trends and characteristics of hospitals that did and did not participate in the ACC voluntary public reporting program. All hospitals reporting procedure data to the National Cardiovascular Data Registry (NCDR) CathPCI or ICD registries that were eligible for the public reporting program from July 2014 (ie, program launch date) to May 2017 were included. Stepwise logistic regression was used to identify hospital characteristics associated with voluntary participation. Enrollment trends were evaluated considering the date US News & World Report (USNWR) announced that it would credit participating hospitals. Data analysis was performed from March 2017 to January 2018. Main Outcomes and Measures: Hospital characteristics and participation in the public reporting program. Results: By May 2017, 561 of 1747 eligible hospitals (32.1%) had opted to participate in the program. Enrollment increased from 240 to 376 hospitals (56.7%) 1 month after the USNWR announcement that program participation would be considered as a component of national hospital rankings. Compared with hospitals that did not enroll, program participants had increased median (IQR) procedural volumes for PCI (481 [280-764] procedures vs 332 [186-569] procedures; P <.001) and ICD (114 [56-220] procedures vs 62 [25-124] procedures; P <.001). Compared with nonparticipating hospitals, an increased mean (SD) proportion of participating hospitals adhered to composite discharge medications after
