“Dead” Infant Heart Revived for Life-Saving Transplant
Duke surgeons pioneer technique to resuscitate organs
Surgeons at Duke University have successfully revived a heart that had ceased beating for over five minutes, performing a groundbreaking transplant on a three-month-old infant. The child is now showing normal cardiac function six months post-operation, demonstrating the potential of “on-table reanimation” for infant heart transplants.
Innovation in Organ Resuscitation
This pioneering procedure involved custom-designing equipment to restart the small donor heart. The system, featuring an oxygenator, centrifugal pump, and hanging reservoir, was specifically adapted because existing organ preservation systems are too large for infant organs. This advancement offers hope in a critical shortage, where as many as 20 percent of infants awaiting heart transplants in the U.S. die.
Navigating Ethical Complexities
The technique utilized organs from donors declared brain dead. However, it also demonstrated success with hearts from donors after circulatory death (DCD), a category representing only 0.5 percent of pediatric heart transplants. DCD occurs when the heart stops beating and blood circulation ceases.
While some critics question the ethical implications of reanimating a heart after circulatory death, proponents argue that performing such procedures outside the donor’s body mitigates these concerns. They also highlight that utilizing DCD organs could expand the donor pool by up to 30 percent.
Vanderbilt’s Alternative Approach
Meanwhile, a separate team at Vanderbilt University has developed a distinct method to address ethical considerations by focusing on organ preservation rather than immediate reanimation. This technique involves clamping the aorta and administering a cold-preserving fluid.
Heart transplantation is a miracle, but what happens when a donor heart stops beating? A groundbreaking new study shows that a ‘dead’ heart can be revived on the operating table and successfully transplanted, offering hope for a generation of babies waiting for a life-saving procedure. https://t.co/XQ9uTqj28k #organdonation #medicalinnovation #transplant

“Our technique flushes oxygenated preservation solution to the donor heart only, without reanimation of the heart and without systemic or brain perfusion,” the Vanderbilt team explained. This approach ensures that the procedure remains distinct from the donor’s brain activity, thereby avoiding potential ethical debates surrounding resuscitation.
Promising Early Results
Initial surgeries using the Vanderbilt method have yielded “excellent early postoperative outcomes,” with all three donor hearts successfully transplanted and functioning healthily. The researchers believe this recovery method has the potential for widespread application.
Both the Duke and Vanderbilt research findings were published in the New England Journal of Medicine.
This dual approach in organ recovery highlights significant progress in transplant medicine, offering new avenues to save lives while meticulously addressing ethical considerations in the donation process.
