Insights

Marginal donor hearts with valvular disease can be used in cardiac transplantation. A bicuspid aortic valve in a donor heart was successfully replaced during surgery, expanding donor heart eligibility.

Area of Science:

  • Cardiology
  • Transplantation Surgery
  • Cardiac Surgery

Background:

  • Critical donor shortages necessitate expanding donor heart eligibility criteria.
  • Marginal donor hearts, previously deemed unsuitable, are increasingly considered.
  • Donor valvular disease was historically an absolute contraindication for heart transplantation.

Observation:

  • A 39-year-old male patient with end-stage non-compaction cardiomyopathy (INTERMACS II, LVEF 8%) underwent orthotopic heart transplantation.
  • During donor graft examination, a congenital, calcified bicuspid aortic valve was identified.
  • This finding presented a potential challenge to utilizing the donor heart.

Findings:

  • The donor's native bicuspid aortic valve was surgically excised.
  • Annular calcification associated with the valve was debrided.
  • A #21 bioprosthetic aortic valve was successfully implanted into the donor heart.

Implications:

  • This case demonstrates the feasibility of addressing donor valvular disease during heart transplantation.
  • It suggests that marginal donor hearts with specific valvular abnormalities can be utilized.
  • Expanding donor heart eligibility criteria may help alleviate donor shortages and improve patient outcomes.
