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 partially or completely, depending on the patient's needs. VADs can be used as a temporary solution while waiting for a heart transplant or as a long-term treatment option. These devices 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 for patients with advanced heart conditions. Regular monitoring and follow-up care are essential for patients with VADs.
