Surgeons perform first combined heart pump and pig kidney transplant
New Jersey's NYU Langone Health has completed the first transplant surgery to combine a mechanical heart pump and a gene-edited pig kidney. Lisa Pisano, 54, had heart failure and end-stage kidney disease that required routine dialysis. She couldn't have a standard heart or kidney transplant due to other chronic medical conditions and an overall lack of donor organs in the US. Experts believe xenotransplants, transplants of animal organs into people, are crucial to solving the organ shortage. Gene editing makes precise edits to a pig's DNA to help keep the human body from recognizing the animal's organs as foreign and rejecting them. Pisano received the heart pump on April 4 and then received a gene-edited pig kidney along with the pig's thymus gland. Her case is the first reported organ transplant in a person with a mechanical heart pump, and the second known transplant of a gene-edited pig kidney into a living recipient and the first transplanted along with the thymus. The kidney came from a pig genetically engineered to disrupt a gene responsible for the production of a sugar found on the surface of animal cells called alpha-gal, which can be recognized by human antibodies and attacked.
