Values are presented as n, n (%), median (interquartile range). Continuous variables were compared using the independent-samples Mann–Whitney U test and categorical variables with Fisher exact test
AVR, aortic valve replacement; ECMO, extracorporeal membrane oxygenation; ICU, intensive care unit
^aTimes of the three patients, who died and one LVAD-receiving patient are excluded
^bIn one case peritoneal dialysis had already been instated prior AVR
^cIn one case ECMO had already been implanted prior AVR
