This is more commonly known as a piggy-back heart.
What is a ghost organ?
This scaffold of connective tissue – called a “ghost organ” for its pale and almost translucent appearance – can then be reseeded with a patient’s own cells, with the goal of regenerating an organ that can be transplanted into the patient without fear of tissue rejection.
How many hearts does a human body have?
The heart is one of the body’s most essential organs.
