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
