A Pioneering Spirit Extinguished: Lisa Pisano's Journey Ends After Groundbreaking Xenotransplant
In a heart-wrenching turn of events, Lisa Pisano, the trailblazer who became the first person to receive a mechanical heart pump and a gene-edited pig kidney, has passed away. Pisano's extraordinary journey, which captured the world's attention and ignited hope for countless individuals awaiting life-saving organ transplants, came to an end on Sunday, as confirmed by NYU Langone Health, where her groundbreaking surgery took place.
Pisano's courageous decision to undergo the pioneering procedure on April 12 marked a significant milestone in the realm of xenotransplantation, the field that explores the use of animal organs for human transplantation. Tragically, her transplanted pig kidney failed due to limited blood flow, necessitating its removal on May 29, just over a month after the historic surgery.
Dr. Robert Montgomery, the director of the NYU Langone Transplant Institute, paid a heartfelt tribute to Pisano, describing her as "brave and altruistic." In a poignant statement, he acknowledged the profound impact of her contributions, stating, "Lisa's contributions to medicine, surgery, and xenotransplantation cannot be overstated. Lisa helped bring us closer to realizing a future where someone does not have to die for another person to live."
Pisano's unwavering determination and selfless spirit were evident even in the face of adversity. During a news conference following the procedure, she expressed her resolute hope, stating, "At least somebody is going to benefit from it," even if the organ transplant did not ultimately work for her.
The dire shortage of available donor organs is a harsh reality that plagues the medical community. According to the Organ Procurement and Transplantation Network, every eight minutes, another person is added to the transplant waiting list, and tragically, 17 individuals from this list succumb to their condition each day while awaiting an organ. Xenotransplantation, the practice of using organs from other species, presents a potential solution to this critical shortage, offering a glimmer of hope for those in desperate need.
In Pisano's case, the FDA granted permission for the groundbreaking procedure through its expanded-access or "compassionate use" policy, which allows terminally ill patients with no other treatment options to access experimental medical products. Faced with heart failure and end-stage kidney disease that required routine dialysis, Pisano could not undergo a standard transplant, making her an ideal candidate for this pioneering approach.
The pig kidney she received was genetically altered to evade human antibodies, which typically detect and attack foreign organs. Additionally, the pig's thymus gland, crucial for immunity, was strategically placed beneath the kidney's cover to further aid Pisano's body in accepting the organ.
Despite the ultimate outcome, Pisano's bravery and determination have left an indelible mark on the medical community. As Dr. Montgomery aptly stated, "Her legacy as a pioneer will live on, and she will forever be remembered for her courage and good nature."
Pisano's journey, though cut short, has paved the way for future advancements in xenotransplantation, offering a beacon of hope to the thousands of individuals living with end-stage kidney or heart failure who could soon benefit from an alternative supply of organs. Her pioneering spirit will continue to inspire generations to come, serving as a testament to the resilience of the human spirit and the unwavering pursuit of medical progress.
