Significance of thyroid dysfunction in human cardiac allograft procurement.

J A Macoviak, I R McDougall, M F Bayer

    Transplantation
    |June 1, 1987
    PubMed
    Summary

    Thyroid function abnormalities in potential heart transplant donors did not correlate with graft outcomes. However, undetected myocardial microinfarcts were found in some donor hearts, impacting transplant suitability and allograft success.

    Area of Science:

    • Cardiology
    • Transplant Surgery
    • Endocrinology

    Background:

    • Cardiac allograft transplantation is a life-saving procedure.
    • Donor selection critically impacts graft survival.
    • Thyroid dysfunction in donors is a potential concern.

    Purpose of the Study:

    • To evaluate the correlation between donor thyroid function and cardiac allograft outcomes.
    • To identify potential undetected cardiac pathologies in potential donors.

    Main Methods:

    • Thyroid function tests were performed on 22 potential cardiac allograft donors before cardiectomy.
    • Graft function and failure were monitored post-transplantation.
    • Histopathological examination of myocardial tissue was performed.

    Main Results:

    • Statistically significant abnormal thyroid function was observed in donors.
    • No correlation was found between donor thyroid function and graft function or failure.
    • Multiple myocardial microinfarcts, undetected during donor selection, were identified in two hearts.
    • A potential link between microinfarcts and allograft failure was suggested.

    Conclusions:

    • Donor thyroid function does not appear to influence cardiac allograft success.
    • Undetected myocardial microinfarcts pose a risk to successful transplantation.
    • Improved donor screening for myocardial pathology is warranted.
