A Ventricular Assist Device (VAD) is a mechanical pump used to support heart function in patients with severe heart failure. It helps the heart pump blood more effectively, either as a temporary solution while waiting for a heart transplant or as a long-term treatment for those who are not candidates for surgery. VADs are typically implanted in the chest and connected to the heart's ventricles. They can improve blood flow to vital organs, enhance quality of life, and increase survival rates. Patients with a VAD often require ongoing medical care and monitoring to ensure the device functions properly.
