The study heterogeneity was substantial. The pooled mean incidence of POD after TAVR in all included studies was 9.8% (95% CI: 8.7%\u201311.0%), whereas that in studies using validated tools to assess for delirium at least once a day for at least 2 consecutive days after TAVR was 20.7% (95% CI: 17.8%\u201323.7%). According to the level of evidence and results of meta\u2010analysis, independent preoperative risk factors with a high level of evidence included increased age, male sex, prior stroke or transient ischemic attack, atrial fibrillation\/flutter, weight loss, electrolyte abnormality, and impaired Instrumental Activities of Daily Living; intraoperative risk factors included non\u2010transfemoral access and general anesthesia; and acute kidney injury was a postoperative risk factor. POD after TAVR was associated with significantly increased mortality (pooled unadjusted RR: 2.20, 95% CI: 1.79\u20132.71; pooled adjusted RR: 1.62, 95% CI: 1.25\u20132.10), particularly long\u2010term mortality (pooled unadjusted HR: 2.84, 95% CI: 1.91\u20134.23; pooled adjusted HR: 1.88, 95% CI: 1.30\u20132.73).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>POD after TAVR is common and is associated with an increased risk of mortality.
