摘　　要：为评估左房主动脉转流作为左心辅助循环在心内直视术后顽固性左心衰竭的应用效果，为２７例术后出现顽固性左心衰竭的病人，经左心房辅助泵主动脉建立左心辅助循环，结果２３例脱离人工心肺机，２０例痊愈出院。死亡原因主要为顽固性心衰、心律失常、出血、多器官功能衰竭等。结果：左心辅助疗效肯定。Aim:This study was undertaken to evaluate the effect of left ventricular assist circulation for left heart failure during cardiac operation.Clinical material and method:From 1994 to 1997,1085 patients underwent open heart surgery.Among them,27 patients developed uncontrollable heart failure requiring left ventricular assist.There were 16 man and 11 women with a mean age of 41.75 years(range,16 to 61 years).The heart function was class III to cluss IV(NYHA).LVEF was 32.78%±10.06%.The mean pulmonary artery pressure was 59.21±16.18mmHg.Result:The mean time of left ventricular assist was 118.36±101.70 minutes(range,25 to 450 minutes).Four patients died during left ventricular assist.The causes of death were uncontrollable arrhythmia and heart failure.3 patients died on postopeatsive day 1,3 and 8,respectively.Overall hospital mortality rate was 25.9%.20 patients survived and recovered excellently.Conclusion:This study suggest that left ventricular assist is an effective technigue for uncontrollable heart failure following open heart surgery.The high hospital mortality rate is closely related to uncontrollable heart failure and arhythmia.
