A heart pump is a medical device designed to assist or replace the function of the heart. It helps circulate blood throughout the body, ensuring that vital organs receive the oxygen and nutrients they need. Heart pumps are often used in patients with severe heart conditions, such as heart failure, where the heart cannot pump effectively on its own. There are different types of heart pumps, including ventricular assist devices (VADs) and total artificial hearts. These devices can be temporary solutions while patients await a heart transplant or long-term options for those who are not candidates for surgery. Heart pumps can significantly improve the quality of life for individuals with serious heart issues.
