A new technique of heterotopic heart transplantation in abdomen was developed on Wistar rats with fifteen experiments. This technique is characterized by termino-lateral anastomosis of donor aorta to recipient abdominal aorta cranially to renal arteries, and anastomosis of pulmonary artery of donor to left renal artery of recipient.

The advantages of this technique are:

  • the abdominal aorta of rats proximally to renal arteries is characterized by a well developed adventitia and its caliber is double of that of infrarenal aorta;
  • the left renal vein is more easily access of caval vein with similar caliber;
  • the use of left renal vein and the widening of pulmonary artery permits a wide anastomosis;
  • the so obtained heart position is better than the transversal one;
  • the calibers of all anastomosis is so wide to permit the realization of this technique without extreme optical magnification.
