Insights

Utilizing valve repair in donor hearts with valvulopathy can expand the donor pool for heart transplantation. This approach can decrease waiting list mortality for patients needing an orthotopic cardiac transplant.

Area of Science:

  • Cardiology
  • Transplantation Surgery
  • Cardiac Surgery

Background:

  • Donor heart shortage leads to prolonged waiting times and increased mortality for transplant candidates.
  • Traditionally, donor heart valvulopathy was a contraindication for organ donation, limiting the available donor pool.
  • Expanding donor criteria is crucial to address the organ shortage in heart transplantation.

Purpose of the Study:

  • To evaluate the outcomes of aortic and mitral valve surgery in marginal donor hearts with valvulopathy prior to orthotopic heart transplantation.
  • To determine the feasibility and efficacy of using donor hearts with valvular disease for transplantation.

Main Methods:

  • Analysis of 53 heart transplantations performed between January 2012 and November 2015.
  • Echocardiography identified valvular disease in four donors: three with mitral regurgitation and one with aortic stenosis.
  • Conventional valvular procedures (mitral repair, aortic valve replacement) were performed on these marginal donor hearts.

Main Results:

  • Surgical procedures on donor hearts included mitral repair (mean 18 min) and aortic valve replacement (mean 78.7 min cross-clamp time).
  • Intraoperative echocardiography confirmed successful valve repair/replacement and good ventricular function.
  • One patient experienced a fatal outcome due to pneumonia; however, the remaining patients achieved long-term recovery and returned to an active lifestyle.

Conclusions:

  • Conventional surgical techniques for mitral and aortic valve pathology in donor hearts are effective.
  • Utilizing these "marginal" donor hearts can significantly expand the donor pool for cardiac transplantation.
  • This strategy has the potential to reduce mortality rates among patients awaiting a heart transplant.
