Abstract:
Objective To study the advantage and disadvantage of two types of rat heart trans- plantation models.Methods Twenty Wistar rats served as donors and 20 SD rats as recipients ran- domly in two groups.Abdominal working and nonworking cardiac transplantation models from Wistar to SD rats were established.In the working model,the donors pulmonary artery was anastomosed to the left atrial appendage.The left ventricle ejected volume through an end to side anastomosis of the donor's aorta to the recipient's abdominal aorta.In the nonworking cardiac transplantation model,the donor's pulmonary artery was anastomosed to the recipient's inferior vena cava and the donor aorta was anastomosed to the recipient aorta.Results Working model and nonworking model were successfully established.The survival rate of both models was 90 %.Total operating time of the working model was 10 min shorter than the nonworking model.Postoperative UCG demonstrated the working trans- planted hearts had ejection.Conclusions Rat abdominal working cardiac transplantation model was used perfectly with high rate of survival and shorter total operating time.The working model approached cardiac physiological functions more than the nonworking model.
