Ex Vivo Perfusion: Keeping Hearts Alive Outside the Body

Yes, a human heart can be kept alive and beating outside of the body for a short period of time through a procedure called ex vivo perfusion. This involves connecting the heart to a machine that provides oxygen and nutrients, and removes waste products, in a similar manner to how a heart-lung machine works during surgery.

This technique has been used for various purposes, such as studying the heart's function, testing new drugs and medical devices, and performing transplant procedures. However, it's important to note that the heart cannot survive indefinitely outside of the body and must be transplanted or returned to the body after a certain period of time.

Scientists and researchers have made advancements in ex vivo perfusion techniques, allowing hearts to be preserved and maintained outside the body for longer durations. This has opened up possibilities for complex surgeries, organ preservation, and further research on heart diseases.
