WHAT IS THE LVAD?

LVAD - is surgically implanted mechanical pump that is attached to the heart. LVAD is different from the artificial heart. Artificial Heart replaces the heart completely, while LVAD works with the heart to help it pump more blood with less work. It does this by continuously taking blood from the left ventricle and the aorta moves it, which then delivers oxygen-rich blood throughout the body. 
LVAD has both internal and external components. In fact, the pump sits on or near the heart of the left ventricle of the heart and connected to the tube that directs the blood to the aorta. Cable called transmission. It comes from the pump, through the skin, and connects the pump to the controller and a power source outside the body. 
Transmission must be connected to the controller and the controller must be connected to the power supply all the time that the pump worked fine. The pump is powered by batteries or electricity. Some LVAD have an adapter that allows them to work on the car battery. Each device has cases to allow you to move freely with the equipment.
