    Abstract:
    The effect of intra-aortic balloon pumping (IABP) on the graft of coronary artery bypass grafting (CABG) was examined. These patients needed IABP when they were weaned from cardiopulmonary bypass. The flow wave pattern in the graft was acquired and analyze by the slope, peak flow rate and area of systolic phase and diastolic phase. The flow wave pattern different between graft to a left anterior branch and the graft to the right coronary artery. IABP was significantly effective for the flow to the left anterior branch. However, the effect of IABP on the graft flow to the right coronary artery was not significant. In the natural heart, the flow rate of the left coronary artery predominates during the diastolic phase. However this predominance is not clear in the right coronary artery. Our results suggested that this phenomenon in the natural state caused a difference the flow wave pattern between graft of left coronary artery and that of the right coronary artery.
