Left atrial appendage occlusion implantations were identified on the basis of the International Classification of Diseases, 10th Revision, Clinical Modification code of 02L73DK. The study sample was stratified on the basis of the CHA2DS2-VASc score into three groups (scores of 3, 4, and \u22655). The outcomes assessed in our study included complications and resource utilization. A total of 73 795 LAAO device implantations were studied. Approximately 63% of LAAO device implantations occurred in patients with CHA2DS2-VASc scores of 4 and \u22655. The crude prevalence of pericardial effusion requiring intervention was higher with increased CHA2DS2-VASc score (1.4% in patients with a score of \u22655 vs. 1.1% in patients with a score of 4 vs. 0.8% in patients with a score of 3, P &amp;lt; 0.01). In the multivariable model adjusted for potential confounders, CHA2DS2-VASc scores of 4 and \u22655 were found to be independently associated with overall complications [adjusted odds ratio (aOR) 1.26, 95% confidence interval (CI) 1.18\u20131.35, and aOR 1.88, 95% CI 1.73\u20132.04, respectively] and prolonged length of stay (aOR 1.18, 95% CI 1.11\u20131.25, and aOR 1.54, 95% CI 1.44\u20131.66, respectively).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>A higher CHA2DS2-VASc score was associated with an increased risk of peri-procedural complications and resource utilization after LAAO.
