One of the most dramatic milestones in artificial organ medicine has been achieved: a patient has survived for roughly 100 days supported by a fully implanted total artificial heart, marking a major step forward in the future of cardiac care. Unlike ventricular assist devices, which help a weakened heart pump, a total artificial heart is designed to fully replace the heart’s function, taking over 100% of blood circulation. These devices often rely on advanced biocompatible materials such as medi
