一種臨時心臟能夠幫助正在等待心臟供體的患者，這些患者往往面臨著死亡的威脅。

CardioWest臨時完全人工心臟(TAH-t)為那些左右兩側心室不可逆衰竭的患者，提供循環功能恢復，使他們能夠等到移植的時刻。TAH-t設計用于填補切除病變心室的空間，適合大多數成年人和絕大多數較大的青少年。該系統使用部分灌注和完全射血機制；當患者活動的時候，他們的肌肉和血管收縮導致更多的血液灌注入心室，然后隨著每一次人工心臟的跳動而完全射血。該設備還能夠將大量血液(最大9.5升/分鐘)安全的泵入整個機體，同時將與非人體表面接觸降至最低。

TAH-t是由SynCardia公司(Tucson, AZ, USA)生產制造的。

Artificial Hearts Prolong Transplant Candidates Lives
 
A temporary artificial heart helps patients who are waiting for a donor human heart and who are at imminent risk of death.

The CardioWest temporary Total Artificial Heart (TAH-t) provides circulatory restoration in morbidly ill patients with irreversible biventricular failure, bridging them to transplantation. The TAH-t is designed to fit in the space of the removed diseased ventricles, and fits in a majority of adults and some larger adolescents. The system utilizes a partial fill and full eject mechanism; as patients exercise, their muscles and blood vessels contract causing more blood to fill the ventricles which is then fully ejected with each artificial heart beat. The device is able to pump high volumes of blood (up to 9.5 l/min) safely through the body while minimizing contact with non-human surfaces.

TAH-t is manufactured by SynCardia (Tucson, AZ, USA).
