BACKGROUND: Right heart failure after heart transplantation represents a life-threatening complication. When conventional therapy including NO-inhalation fails the only choice to reach sufficient haemodynamic conditions may be the implantation of a right ventricular support system. METHODS: In all cases the Biomedicus centrifugal pump was implanted by cannulation of the right atrium and pulmonary artery. RESULTS: Since March 1989 950 heart transplant procedures were performed at our center. In nine cases (7 male, 2 female, mean age 52 years) implantation of a right ventricular support system was necessary because of deterioration of right ventricular function. The implantation was carried out in 7 cases immediately after transplantation, in 2 cases after 2 days. The support time ranged from 4-348 hours. Six patients could be weaned, 2 patients underwent retransplantation and died and 1 patient died on the support system. Three of the six weaned patients died in the further course because of multiorgan failure. CONCLUSIONS: Mechanical right ventricular support is often the only therapeutical tool to reach adequate haemodynamic conditions in post-transplant right heart failure. The Biomedicus centrifugal pump provides good conditions in these cases. Weaning is often possible after short-term support. The mortality rate is determined by multiorgan failure in immuno-suppressed patients. Retransplantation seems not to be successful despite maximal treatment.
