Artificial Heart (Left Ventricular Assist Device)

Several models of ventricular assist devices (VADs) — also called artificial heart devices
— exist.

Device selection depends on many criteria, such as:

  • Blood type
  • Medical history
  • Presence of a bleeding disorder
  • Body size

Devices provide left, right, or both left and right heart support.

Your doctors will know which one is right for you. In some cases, your condition will dictate your doctor's decision.    

From recovery to repair to replacement pie chart.
UPMC has implanted 722
ventricular assist devices
from a variety of manufacturers.
