If you have reached a stage of advanced heart failure where your heart is no longer able to pump enough blood to meet your body’s needs, your may recommend LVAD (left ventricular assist device) implant surgery. Today’s LVADs are used in three different ways:
An LVAD is a surgically implanted mechanical pump that is attached to the heart. An LVAD is different from an artificial heart. An artificial heart replaces the failing heart completely whereas an 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 moving it to the aorta, which then delivers oxygen-rich blood throughout the body.
The LVAD has both internal and external components. The actual pump sits on or next to your heart’s left ventricle with a tube attached that routes the blood to your aorta. A cable called driveline extends from the pump, out through the skin, and connects the pump to a controller and power sources worn outside the body.
The driveline must be connected to the controller, and the controller must be connected to power at all times to keep the pump working properly. The pump is powered by batteries or electricity. Some LVADs have an adaptor that also allows them to run off the car battery. Each device has specific carrying cases to allow you to move about freely with your equipment.

There are several different LVAD models available today. Each has unique engineering characteristics and different external equipment, but they all serve the same function. Today’s LVADs are quite different from earlier models, which were larger, noisier and less durable, with bulkier power sources. Now LVAD model is much lighter and smaller and also easy to handle. we had implanted LVAD mechanical pump to 4 patients since one year and all of them are living normal life as per we planned. We are using the brand from Heart mate 2 and heart ware which is from American based company. As LVAD technology continues to improve, so does the quality and quantity of life for LVAD patients: today’s LVAD patients. Today's LVAD patients have at least an 85% one-year survival rate* and can enjoy fulfilling lives and in many cases even return to work. By contrast, advanced heart failure with medical therapy alone is known to have a 25–50% one-year survival rate.
