Cardiologists and doctors usually recommend ventricular assist device (VAD), a type of mechanical pump, for individuals who have weakened hearts or suffer from severe heart failure. Patients awaiting a heart transplant or undergoing a long-term treatment find these devices useful. These mechanical pumps are surgically placed to support heart function and blood flow in people with heart failure (HF). The equipment is used in combination with other specialized treatments such as mechanical circulatory support system; the device does not replace the native heart but prolongs its life. The device takes blood from the lower chambers of the heart and pumps it to the vital organs of the body.
Basically two types of VAD are used—left ventricular assist device (LVAD) and right ventricular assist device (RVAD)—the former being most commonly used for treating HF. RVADs are usually used after LVAD surgeries or other heart surgeries, particularly for short-term support functions. RVAD, also called a "bridge to transplant," is often used in longer-term therapies. It helps the right ventricle to pump blood to the pulmonary artery. Increasing incidence of advanced HF across regions is a key factor boosting the growth of the VAD market. Growing use of the device in ‘destination therapy’ where it is surgically inserted for long-term support in patients who cannot undergo transplantation is expected to create ample growth opportunities in the market in the developed regions.
