Abstract: In order to explore the application value of two-dimensional and three-dimensional echocardiography in evaluating cardiac function and morphological changes after heart transplantation,a total of 41 patients underwent heart transplantation were selected as the observation group, and 41 patients underwent healthy physical examination during the same period were selected as the control group. 7 days after surgery, two-dimensional and three-dimensional ultrasound examinations were performed. It was found that the left atrial inner diameter (LAD), left ventricular end-systolic diameter (LVESD) of the observation group were greater than those of the control group at 7 days after operation, and the left ventricular ejection fraction (LVEF) was lower than the control group (P<0.05). After 3 months of follow-up, LAD, LVESD and left ventricular mass(LVM) of those occurred rejection in the observation group were greater than those without rejection, and LVEF and left ventricular stroke volume (LVSV) were less than those without rejection (P<0.05). After 3 months of follow-up, LAD, LVESD, LVM of the deceased in the observation group were greater than those of the survivor, and LVEF and LVSV were less than those of the survivor(P<0.05). The combination of LAD, LVESD, LVEF, LVM and LVSV to predict the rejection and prognosis of patients after heart transplantation had the largest AUC. It is suggested that two-dimensional and three-dimensional ultrasound parameters have a certain evaluation value for cardiac function and morphology after heart transplantation, and they are expected to become a potential method to predict rejection and prognosis after heart transplantation, and to guide the reasonable treatment to improve the prognosis of patients.
