Abstract
The position of an implanted artificial heart inside a calf was evaluated using a new and innovative method of necropsy. In the past the conventional method of necropsy with the calf on its back or side has failed to reveal the significance of these problems concerning positioning of the artificial heart. Using a new method introduced here, with the calf suspended as if it were standing on its four legs, a better understanding and evaluation of the artificial heart inside the thoracic cavity is possible.
It was found that the major cause of distortion of the Kwan-Gett artificial heart from the desired position was the lack of space available due to its large ventro-dorso dimension. A new Jarvik artificial heart with a shorter ventro-dorso diameter was shown, by the new method of autopsy, to solve the problem of distortion (impingement on the great veins).
