BackgroundIdentifying transcatheter aortic valve replacement (TAVR) patients at high risk for cerebrovascular events (CVE) is of major clinical relevance. However, predictors have varied across studies.ObjectivesThe purpose of this study was to analyze the predictors of 30-day CVE post-TAVR.MethodsA systematic review of studies that reported the incidence of CVE post-TAVR while providing raw data for predictors of interest was performed. Data on study, patient, and procedural characteristics were extracted. Crude risk ratios (RRs) and 95% confidence intervals for each predictor were calculated.ResultsSixty-four studies involving 72,318 patients (2,385 patients with a CVE within 30 days post-TAVR) were analyzed. Incidence of CVE ranged from 1% to 11% (median 4%) without significant differences between single and multicenter studies, or according to CVE adjudication availability. The summary RRs indicated lower risk for men (RR: 0.82; p = 0.02) and higher risk for patients with chronic kidney disease (RR: 1.29; p = 0.03) and with new-onset atrial fibrillation post-TAVR (RR: 1.85; p = 0.005), and for procedures performed within the first half of center experience (RR: 1.55; p = 0.003). The use of balloon post-dilation tended to be associated with a higher risk of CVE (RR: 1.43; p = 0.07). Valve type (balloon-expandable vs. self-expandable, p = 0.26) and approach (transfemoral vs. nontransfemoral, p = 0.81) did not predict CVE.ConclusionsFemale sex, chronic kidney disease, enrollment date, and new-onset atrial fibrillation were predictors of CVE post-TAVR. This study provides effect estimates to identify high-risk TAVR patients for early CVE, providing possible guidance for tailored preventive strategies.
