A technical modification of heart-lung transplantation in rats.

Hemodynamic studies were carried out on a series of rats undergoing heart-lung transplantation according to the technique of Sun Lee. The results suggested a new hypothesis of blood circulation in the heart-lung block by demonstrating the lack of necessity for the venovenous anastomosis. A new technique, with just one aortoaortic anastomosis, was therefore evaluated. Its value and reliability in a series of 30 rats are discussed.
