Ventricular assist device (VAD) - Mayo Clinic


Although a VAD can be placed in the left, right or both ventricles of your heart, it is most frequently used in the left ventricle. When placed in the left ventricle it is called a left ventricular assist device (LVAD). You may have a VAD implanted while you wait for a heart transplant or for your heart to become strong enough to effectively pump …

Between June 1996 and March 1997, 42 children (aged 2 days-13 years) undergoing elective cardiac surgery were assigned to either centrifugal or roller pump bypass.

Ventricular assist device - Wikipedia


Pumps. The pumps used in VADs can be divided into two main categories—pulsatile pumps, that mimic the natural pulsing action of the heart, and continuous flow pumps. Pulsatile VADs use positive displacement pumps. In some pulsatile pumps (that use compressed air as the/an energy source), the volume occupied by blood varies during the pumping cycle.If the pump …
