Abstract :
Despite the progresses in developing pulsatile impeller pump and impeller total heart, as well as in applying streamlined impeller vanes, the best results in application of artificial heart pumps have been achieved by nonpulsatile univentricular assist pump with straight impeller vanes until now. It seems all efforts and successes have been done in vain because artificial heart rejects HiTech! This paper recalls some important achievements in R&D of artificial heart in past 25 years and shares author´s experiences with the readers.
