In January, it was confirmed that the patient who received the world's first genetically engineered pig heart in the United States died two months later.



The University of Maryland Medical Center said that 57-year-old David Bennett, who underwent a pig heart transplant, died on the 8th.



While the exact cause of death is still unknown, it is said that the medical staff only revealed that the patient's condition began to deteriorate a few days ago.



Previously, in January, the University of Maryland Medical Center transplanted a genetically modified pig heart with the consent of Mr. Bennett, a terminally ill heart patient who had no other options because he could not receive human organs.



At that time, the researchers reported that the patient did not show any rejection and was recovering three days after the transplant operation, and Mr. Bennett received worldwide attention.



However, controversy arose when it was later revealed that he was a heinous criminal who was sentenced to 10 years in prison for committing a felony.



With Mr. Bennett's death, the full success of an animal organ transplant remains a challenge.
