Abstract
In our institute, we had the 215 clinical cases that were supported by two types of assisted circulation, (IABP: 199, VAD: 16), after severe cardiac operation. Post-operative courses and the complication were examined, in detail, and post-operative management for these cases was studied. The prognosis in early application cases of assist device was better than that in late application cases. The dead cases that had been complicated multiple organ failure (MOF) were suffered from low cardiac out-put, and had the tendency of the right ventricular failure. In addition, MOF cases had the deterioration of major organ failure, even in during support. Opportunistic infection of VAD cases occured after the removal of VAD. These results suggest that, in order to get the long survival of assisted circulation cases, early application, prevent MOF, and the management for infection are necessary.
