Open heart surgery without cross clamping aorta under normothermic or hypothermic cardiopulmonary bypass was performed in 167 patients in which there were more than ten kinds of cardiac diseases. The characteristics of the procedure included only vena cava blocked and aorta unclamped with beating heart or artificial evoked ventricular fibrillation. It diminished myocardial ischemia and reperfusion injuries maximally. There were no low cardiac output syndrome, severe arrhythmia and complications of brain except two patients died postoperatively. The operative mortality rate was 1.1% (2/167). The advantages, disadvantages and safety of this method are discussed briefly in this paper.
