3. V e n t ricular A s s i s t D e v i c e s A surgically implanted MCS device that is intended for use outside the hospital. The purpose of a VAD is to support patients with HF by increasing perfusion and reducing the filling pressures in the heart. However, VADs only assist the pumping action of the diseased ventricle, which can fill and contract, albeit at a reduced cardiac output. In patients with advanced HF who undergo VAD placement, the device augments but does not completely replace the function of the heart.

4. Typically, VADs consist of an "inlet cannula" (ie, a rigid metal tube) that directs blood from the left ventricle (LV) into an electrical motor, which continuously pumps blood into the aorta via a flexible "outflow graft" . The VAD motor receives power via a n insulated cable that extends through a tunnel in the skin to an external controller connected to batteries. The patient and their caregiver team use the controller to receive basic information about the pump’s settings, power consumption, and battery life. The controller also generates alarms indicating low battery power or other abnormalities that require the attention of the patient or their caregiver.

7. L o n g -term management consists of: Frequent follow-up to assess for device-related complications and residual HF Lifelong maintenance of anticoagulation and antiplatelet therapies Self-care such as battery management as well as driveline wound maintenance Optimal treatment of chronic conditions (eg, chronic kidney disease, depression) Appropriate assessment for heart transplantation
