Experience and procedure of the model of rat heterotopic heart transplantation / 中国医师杂志

ABSTRACT

ObjectiveTo summarize the method and experience of the model of rat heterotopic heart transplantation and to improve the rate of success of the experiment.Methods120 heterotopic heart transplantations were performed by Ono's way,including 60 prepared transplantations and 60 formal transplantations.ResultsRate of success of prepared transplantations was 45％,and formal transplantation was 85％.Mean time of formal operation was (74.3±17.1)min,removal time of the donor heart was (7.9±4.2)min,ischemia time was (29.6±10.3) min and the survival time of allograft was (11.1±5.7)days.5 of the recipients had a long-term survival,and the maximum weight was 740 g.ConclusionsGood surgical technique and rigorous perioperative management is very important in setting up the rat model of heterotopic heart transplantation.
