Predictors, Incidence, and Outcomes of Patients Undergoing Transfemoral Transcatheter Aortic Valve Implantation Complicated by Stroke: From the CENTER-Collaboration

BACKGROUND:Stroke remains one of the most devastating complications of transcatheter aortic valve implantation (TAVI). The aim of this study was to identify the incidence, timing, temporal trends, and predictors of stroke after TAVI and evaluate the outcomes of patients with stroke. METHODS AND RESULTS:The CENTER-Collaboration is an international collaboration consisting of 3 national registries and 7 local registries or prospective clinical trials, selected through a systematic review. Accordingly, a total of 10 982 patients undergoing transfemoral TAVI between 2007 and 2018 were included in the current patient-level pooled analyses. A total of 261 patients (2.4%) experienced stroke during the first month after TAVI. The median time between TAVI and stroke was 1 day (interquartile range, 0–6 days). The stroke rate was comparable in procedures performed in the early years of TAVI (2007–2012) to those in the more recent years of TAVI (2013–2018; both 2.4%; P=1.0). Independent predictors of stroke at 30 days were a history of cerebrovascular events (odds ratio, 2.2; 95% CI, 1.4–3.6; P=0.0012) and a glomerular filtration rate of
