Abstract
In congenital heart diseases, almost all assisting ways were not effective, and the results were mainly depending on the operative indication, techniques and procedures. In acquired valvular heart diseases, prophil ctic use of IABP for postoperative low cardiac output syndrome would improve the operative outcome. By the cases, in that the bypass flow rate above 2.4l/min/m2 and bypass time more than 100 minutes were needed, the prognosis was very poor. As for the combined use of IABP and V-A bypass or ECMO, the combination therapy was considered effective, and particularly early introduclion of IABP for weaning from the extracorporeal circulation was most effective. However, even by the combination assist some cases could not be improved as in almost all cases of ECMO. Then, some other more effective and active assisting ways, such as the left ventricular or biventricular assist devices, and/or heart transplantation will be indicated when a high bypass flow rate is needed for many hours.
