Aortic X-clamp-time = aortic cross-clamp time; CPB time = cardiopulmonary by-pass time; ECMO = extracorporeal membrane oxygenation; ICU = intensive care unit; LOS = cardiac low output syndrome; MOF = multi organ failure; PM = pacemaker.1 Continuous variables are expressed as median and interquartile range.
