AKI was defined according to the \u2018Kidney Disease Improving Global Outcome\u2019 (KDIGO) initiative. Variables on co-morbidities, intra-\/post-interventional complications and course of renal function up to 6\u2009months after index-hospitalization were assessed. In multivariate regression analyses, risk factors for the development of AKI, complicated AKI, renal non-recovery from AKI and in-hospital mortality were determined.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Incidence of AKI was 13.8% (111\/804); in-hospital mortality after TAVI was 2.3%. AKI was an independent risk factor for in-hospital mortality, odds ratio (OR) 10.3 (3.4\u201331.6), P\u2009&amp;lt;\u20090.001, further increasing to OR = 21.8 (6.6\u201371.5), P\u2009&amp;lt;\u20090.001 in patients with AKI complicated by hyperkalaemia, pulmonary oedema or metabolic acidosis, n\u2009=\u200957\/111 (51.4%). Potentially modifiable, interventional factors independently associated with complicated AKI were infection [OR = 3.20 (1.61\u20136.33), P\u2009=\u20090.001] and red blood cell transfusion [OR = 5.04 (2.67\u20139.52), P\u2009&amp;lt;\u20090.001]. Valve type and size, contrast volume and other intra-interventional characteristics, such as the need for tachycardial pacing, did not influence the development of AKI. Eleven of 111 (9.9%) patients did not recover from AKI, mostly affecting patients with cardiac decompensation. In 18\/111 (16.2%) patients, information concerning AKI was provided in discharge letter. Within 6\u2009months after TAVI, higher proportion of patients with AKI showed progression of pre-existing chronic kidney disease compared with patients without AKI [14\/29, 48.3% versus 54\/187, 28.9%, OR = 2.3 (95% confidence interval 1.0\u20135.1), P\u2009=\u20090.036].<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>AKI is common and may impede patient outcome after TAVI with acute complications such as hyperkalaemia or metabolic acidosis and adverse renal function until 6\u2009months after intervention.
