Implantation of the wearable Novacor electrically powered left ventricular assist system was performed on March 16, 1993, in a 44-year-old man hospitalized for an acute episode of myocardial decompensation after a 6-year history of dilated cardiomyopathy. He was rehabilitated fully and became ambulatory, awaiting a suitable cardiac graft for 59 days. He is now back to work, enjoying a normal life. This case illustrates the progress made by miniaturization of the external components of the system. General acceptance of the system and psychological adaptation to the new way of life were remarkable.
