The treatment of heart transplantation includes in situ heart transplantation, where the patient’s diseased heart is removed and the allogeneic donor heart is replaced in its original location, with biventricular anastomosis and biventricular anastomosis. The biventricular anastomosis sutures the left atrium, the right atrium, and then the aorta and pulmonary artery. Biventricular anastomosis is anastomosis of the left atrium of the donor with the pulmonary vein of the recipient, and the upper and lower vena cava are anastomosed to the right atrium alone, which can maintain the shape of the heart, improve the function of the atrioventricular valve, preserve the function of the sinoatrial node, and improve right heart failure and tricuspid valve insufficiency, and is suitable for inconsistent donor size. There is also an ectopic heart transplant, which is a heart implant that is placed next to the patient’s own heart without removing the autologous heart and can serve as an adjunct to the original heart.
