The impact of postoperative delirium (POD) on these long-term complications remains controversial. We intended to illustrate the neurological and neuropsychiatric outcome associated with the occurrence of POD in patients undergoing elective cardiac surgery or percutaneous valve replacement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We included 179 patients who underwent elective cardiac surgery or percutaneous valve replacement. Patients were evaluated postoperatively for delirium status. Neurological (score A) and neuropsychiatric (score B) outcomes were assessed using a structured examination protocol and interview at 1 year postoperatively and combined into a composite neurological and neuropsychiatric score (score A\u2009+\u2009B). Cognitive function was examined using the Montreal Cognitive Assessment (MoCA). Depression, fatigue and quality of life were assessed using the Beck's Depression Inventory (BDI), the Fatigue Impact Scale (FIS) and the Short-Form Health Survey (SF-12). Clinical outcome was assessed using the Barthel-Index (BI) and Frailty Index (FI). All data were collected prospectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      One year after cardiac surgery or percutaneous valve replacement, a high number of patients suffered from neurological and neuropsychiatric symptoms with depressive symptoms (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200936, 20.1%) and symptoms of fatigue (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200972, 40.2%).
