A ghost heart is an incredible new piece of medical technology invented Doris Taylor, Ph.D., FACC, FAHA. She is an American scientist working in regenerative medicine and tissue engineering. A ghost heart is a biohybrid heart, which combines a pig heart and mechanical parts. It gets injected with hundreds of millions of stem cells from a person who needs a heart transplant, and then placed in a bioreactor. Then artificial lungs and tubes pump oxygen and blood into it and it begins to mature into a new, beating heart. Science is beautiful. This is truly amazing and could be a game changer once perfected:
