On March 16, a team of skilled surgeons at MGH performed the revolutionary surgery, transplanting a genetically-edited pig kidney into Slayman’s body. The four-hour procedure was deemed a success, offering new hope for thousands of people awaiting transplants.


Slayman, who had been living with type 2 diabetes and hypertension for years, had previously undergone a kidney transplant from a deceased human donor in 2018. However, the transplanted kidney failed five years later, forcing him to resume dialysis in May 2023.

Despite the challenges he faced, Slayman remained optimistic and courageous, inspiring his loved ones and the medical community with his determination. His family praised his kindness, sense of humor, and dedication to those around him, saying, “Rick accomplished his goal of providing hope for others, and his legacy will endure forever.”

Slayman’s pioneering spirit and selflessness have opened doors to new possibilities in organ transplantation, offering a beacon of hope for those waiting for a life-saving transplant. His memory will live on through the countless lives he has touched and the medical advancements that will continue to evolve as a result of his bravery.
