Assistant artificial heart is generally used to release the workload of a bio-heart whereby to help a patient survive longer. However, due to the difficulty in directly carrying out in vivo experiment on the human body, evaluating the performance of an artificial heart has long been a problem. This paper proposes a mathematical model with which to evaluate the hemodynamic impact of implanting an artificial heart on the bio-heart and the circulatory system. In the model, the human circulatory system is represented by a lumped parameter model and an artificial heart is described by a series of parameters. With the model, the performance of an implanted artificial heart is examined under several cardiac disease conditions in terms of the total cardiac output, the change of bio-heart volume, etc. Given further development, the present model might be expected to contribute as a useful mathematical adjunct for designing patient-specific artificial heart.
