The 2024 European Society of Cardiology guidelines introduced the CHA 2DS2-VA score, removing female sex as a risk modifier, with potential implications for non-cerebral embolic risk stratification. We systematically synthesized evidence on VEE incidence, mortality, and risk predictors in AF patients. Methods: We searched PubMed, Embase, Scopus, and Web of Science through September 2024 for studies reporting VEE in AF populations. Study quality was assessed using the Newcastle–Ottawa Scale (NOS) . Due to substantial heterogeneity when pooling all prevalence studies (I2 = 99.6%), we performed event-definition-based subgroup analyses. Random-effects meta-analyses were conducted using DerSimonian–Laird methods with 95% prediction intervals. Sensitivity analyses excluded studies with NOS scores \u003C 7 to assess robustness. Results: We identified 12 studies including 329,128 patients. Quality assessment revealed a mean NOS score of 6.7 ± 1.6 (range: 4–9), with 75% of studies achieving good-to-excellent ratings. For non-AMI visceral embolic events (splenic, renal, mesenteric infarctions), subgroup meta-analysis of three studies (n = 548) yielded a pooled prevalence of 1.6%(95% CI: 0.0–3.2%, I2 = 45.4%, p = 0.160), representing a 54.2 percentage point reduction in heterogeneity compared to pooling all event types. Sensitivity analysis excluding moderate-quality studies confirmed robust findings (pooled prevalence 2.7%, 95% CI: 0.0–6.8%, I2 = 70.3%) . Incidence rates ranged from 0.36 to 3.48 per 1000 personyears across three cohort studies (I2 = 99.4%), reflecting temporal and geographic variation. Mortality varied substantially by patient population: 64.0% in-hospital mortality among elderly patients with concurrent acute myocardial infarction (AMI) versus 17.4% in younger cohorts with isolated non-AMI VEE. Potential predictors included left atrial enlargement (OR range: 2.1–4.3), elevated D-dimer ","cbCaicTB45iY69KK","https://ap.wps.com/l/cbCaicTB45iY69KK","pdf",2230231,29,"English","# Abstract\n## Background\n## Methods\n## Results\n## Conclusions\n# 1.
