A ventricular assist device (VAD) is a mechanical circulatory device that supports blood flow from the left ventricle to the rest of the body, and is typically used in cases of weakened heart or heart failure. Its primary function is to provide temporary circulatory support for patients awaiting heart transplantation, but in some cases, may be used as a permanent solution for advanced heart failure. This article will focus on Left Ventricular Assist Devices (LVADs), placed most frequently in the left ventricle, which provide continuous flow of blood from the heart to the body. The implantation of an LVAD involves major open-heart surgery and carries significant risks, however, it is a potentially lifesaving treatment option for severe heart failure.
