Ventricular Assist Devices
What is a Ventricular Assist Device?
A ventricular assist device (VAD) is a mechanical heart pump that can be implanted in the chest or worn outside the body. VADs can also be called a ventricular assist system (VAS), heart pump, or left ventricular assist device (LVAD).
This surgically implanted medical device is for patients who have a weakened heart or heart failure. If your heart is too weak to pump sufficient blood throughout your body on its own, the VAD takes over much of the work.
Dr. Niloo Edwards, Chief of Cardiac and Vascular Services at St. Peter's Hospital, is a national leader in VAD research, placement, and the long-term management of these devices.
