The Italian Artificial Heart Program.
In Italy, artificial heart development was promoted by virtue of a special program on technological and industrial development in areas related to cardiology and cardiosurgery. A first prototype series of electromechanical total artificial hearts (TAHs) and ventricular assist devices (VADs), with ball-screw-based actuation technology, has been developed, and preliminary bench tests and short-term animal implant experiments were performed. The project started with analysis and development of existing TAH and VAD models, and it included a fill-sensor-free control scheme and anatomical fitting studies using a three-dimensional computer model of the chest cavity. Second-generation prototypes are currently being developed, and they are scheduled for medium-term bench and in vivo testing by early 1994.
