A left ventricular assist device (LVAD) is a mechanical pump that is implanted into the chest to help the heart pump blood to the rest of the body. This device is typically used in patients with advanced heart failure who are awaiting a heart transplant, or in some cases, as a permanent therapy for those who are not eligible for transplantation. LVADs can significantly improve the quality of life and survival of patients with severe heart failure. They work by taking blood from the left ventricle of the heart and pumping it into the aorta, which then delivers oxygen-rich blood to the rest of the body. Research in the field of LVADs focuses on improving the technology and design of these devices to make them more durable, reliable, and efficient. Additionally, studies are also being conducted to better understand the long-term impact and outcomes of using LVADs as a treatment for heart failure.
