Seattle dentist Barney Clark received the first artificial heart implant in 1982. He died in March 1983, having survived 112 days with the world's first permanent, pneumatic, totally artificial heart. NOVA follows the case with the surgeon, William DeVries, and looks at the prospects for this technology to save lives. It also explored the work of Dr. William F. Bernhard on the Left Ventricular Assist Device (LVAD) ongoing at the Cardiovascular Surgical Research Laboratories, Boston Children's Hospital Medical Center.
