Abstract:
Objective To study the characteristics of heterotopic heart transplantation by echocardiographyand evaluate the heart function and acute rejection.Methods Five male 49-61 years old patients with heterotopic heart transplantation were studied using echocardiography pre-,intra-,post～operation and at follow-up.The anastomoses of great vessels of recipient with donor heart,chamber size,left ventricular wall thickness with wallmotion.left ventricular ejection fraction(LVEF),valvular function,pulmonary artery pressure,pericardial and pleural effusion were observed.Results All patients were end-stage coronary artery disease with NYHA class of received heterotopic heart transplantation with coronary artery bypass grafting.Some patients received mitral valvuloplasty,ventricular aneurysmectomy and stem cell transplantation simultaneously.During the operation,intra-operation transesophageal echocardiography was used to monitor and evaluate the surgical procedure with chamber sizes,anastomoses,native with donor heart ventricular and valvular function,and air bubble in chambers.The cardiac functions of donor heart backed to normal post operation,while the functions of recipient heart were increased gradually.All patients survived in 6 months and one year follow-up,with significantly improved functions of heart in situ[LVEF(44.0±15.6)%].The main reject reaction was small pericardial perfusion and pleural effusion.Conclusions Heterotopic heart transplantation has distinctive characteristics with echocardiography study,which is also an important technique in evaluation at pre-,intra-,post-operation and also at follow-up.
