An artificial heart is a device that is implanted to replace a failing biological heart. This synthetic replacement of the heart is distinct from external devices that are developed to provide the functions of a mammalian heart. According to scientists, a functional synthetic heart would greatly benefit modern medicine, lowering the demand for heart transplants. Learn more about the device, its development and similar inventions as well as researchers that have contributed to the creation of a synthetic heart in this book.
