[Intra-abdominal transplantation of the heart in rats].

3 variants of microsurgical intraabdominal heart transplantation technique in rats are described. In the first variant heart transplantation was performed with anastomosis of the transplant aorta and pulmonary artery with the abdominal aorta and v. cava caudalis of the recipient. In the second variant heart was transplanted in complex with the lungs, performing anastomosis of the transplant aorta with the abdominal aorta of the recipient. The lungs acted as a shunt for venous coronary blood flow from the transplanted right heart into the left heart and further into the aorta of the recipient. The third variant included transplantation of the heart with a right lung lobe. A total of 68 intraabdominal heart transplantations was performed with 57 (84%) successful cases. Maximal term of follow up was 9 months.
