Marvin J Slepian and Jack G Copeland present their Viewpoint on the University of Arizona's experience with the CardioWest™total artificial heart (TAH-t) in patients with protracted refractory cardiogenic shock accompanying acute myocardial infarction. The authors assert that the TAH-t could provide a lifeline to patients whose prognosis would otherwise be bleak.
