An artificial heart is a medical device designed to replace a failing human heart. It helps pump blood throughout the body, ensuring that vital organs receive the oxygen and nutrients they need. Artificial hearts can be temporary solutions while patients await a heart transplant or serve as permanent replacements for those who are not candidates for surgery. These devices can be either total artificial hearts, which replace the entire heart, or ventricular assist devices (VADs), which support the existing heart. Advances in technology have improved the design and functionality of artificial hearts, making them more effective and increasing patient survival rates.
