Groundbreaking Heart Repair Surgeries at Duke Health Save Lives, Improve Organ Stewardship

Strategic Insights -

Researchers at Duke Health have made significant strides in heart repair surgeries, pioneering two world-first procedures: living mitral valve replacement and heart reanimation. These innovations have not only saved young lives but also emphasized the importance of organ stewardship. The team's work involves developing novel techniques to assess and utilize donor hearts from children, overcoming current limitations in perfusion technologies. The results of these advancements are exemplified in the case of an adolescent girl who received a full heart transplant and donated her healthy valves, which were then used to save two other girls' lives. Additionally, a 3-month-old patient received a reanimated donor heart earlier this year, thanks to the team's on-table heart reanimation technique.

Key Takeaways:

  • The Duke Health team has successfully performed two world-first heart repair surgeries: living mitral valve replacement and heart reanimation.
  • The living mitral valve replacement procedure uses healthy valves from a donor heart, which were obtained after a 14-year-old girl received a full heart transplant at Duke University Hospital.
  • The adolescent girl who donated her healthy valves is from Gastonia, North Carolina, while the other two recipients are from Greensboro and another part of North Carolina, showcasing the team's ability to utilize donor hearts from various regions.
  • The novel technique developed by the Duke team, on-table heart reanimation, temporarily reanimates the donor heart outside the body, enabling surgeons to assess its viability before transplant.
  • Partial heart recipients at Duke receive immunosuppression at a dosage considered non-life-altering and have continued to grow and thrive since the first partial heart procedure three years ago.
  • Paediatric heart surgeon Douglas Overbey, MD, MPH, was part of the team performing the operations, highlighting the multidisciplinary approach to these innovations.
  • Both techniques have the potential to save as many young lives as there are viable paediatric donor hearts currently going unused, with current statistics indicating a significant number of unused donor hearts.
  • Duke has performed over 25 partial heart transplants to date, including domino and living Ross procedures, demonstrating the centre's experience and success in paediatric heart surgery.
  • The current standard of care for paediatric heart valve replacement uses preserved non-living tissue or mechanical valves, which do not grow along with the child, requiring multiple future surgeries and blood thinners.

Statistics:

  • 3 patients benefited from one donor organ in the living mitral valve replacement case, with all three recipients doing well and the adolescent recipient returning to competitive running.
  • The adolescent recipient of the full heart transplant who donated her valves is from Gastonia, North Carolina.
  • 25 partial heart transplants have been performed at Duke to date, including domino and living Ross procedures.
  • Over 100 paediatric donor hearts are unused each year in the United States, with the potential for these new techniques to save many young lives.
