Haemoadsorption During Heart Transplantation

To investigate whether the use of haemoadsorption (HA) on cardiopulmonary bypass during heart transplantation (HTX) has an effect on circulating cytokine levels for the first 120 hours after HTX and induces a decreased inflammatory response, increased anti-inflammatory response or immunosuppressive response. Additionally, the influence of HA on primary graft dysfunction, postoperative cerebral dysfunction, postoperative fluid accumulation, renal dysfunction, duration of mechanical ventilation, length of ICU-stay and 30-day mortality should be investigated
