The correct answer is (D) USA
In January 2022, doctors in the United States successfully transplanted a genetically modified pig’s heart into a human patient in a historic first-of-its-kind surgery.
The transplant was performed at the University of Maryland Medical Center by a team led by Dr. Bartley Griffith.
The recipient, David Bennett Sr., was a 57-year-old man who had end-stage heart disease and was not eligible for a traditional human heart transplant.
Information Booster:
The pig used for the transplant was genetically modified to reduce the risk of organ rejection by the human immune system.
This groundbreaking procedure is part of the field of xenotransplantation, which involves transplanting organs from animals to humans.
Although the patient survived for about two months, the transplant provided valuable insights into overcoming organ shortages.
The heart came from a pig developed by Revivicor, a biotechnology company specializing in genetically engineered animals for medical use.
