Objective To summarize successful experience in three of orthotopic homoplastic heart transplantation,to explore some problems for donor myocardial protection,the application of immunosuppressive drugs,anti-infection and prevent acute rejection.Methods From 2000.11.to 2001.3,we performed successful three cases orthotopic homoplastic heart transplantation;one case of hypertrophic myocardosis in terminal phase, one case of dilatanay myocardosis and one case of geneogenous tricuspic valve atresia.Postoperation,cyclosporin A,methylprednisolone,prednisolone and other immunosuppressive drugs have been used.Results Three patients have survived for three and six months with normal heart function and a good life quality.Conclusion Successful keys of heart transplantation are donor myocardial protection,technology of anastomosis and treatment of peroperation.
