Pathologic findings in long-term cardiac transplants.

C J Uys, A G Rose

    Archives of Pathology & Laboratory Medicine
    |February 1, 1984
    PubMed
    Summary

    Long-term cardiac transplant survivors often experience advanced chronic rejection, primarily due to obliterative arteritis. This vascular damage, mimicking atherosclerosis, frequently leads to graft failure or death in heart transplant recipients.

    Area of Science:

    • Cardiology
    • Transplantation Immunology
    • Pathology

    Background:

    • Cardiac transplantation has advanced significantly, leading to more long-term survivors.
    • Monitoring and treatment protocols have improved patient outcomes post-transplant.

    Purpose of the Study:

    • To define the pathological features of cardiac transplants with survival exceeding one year.
    • To identify the primary causes of graft failure and mortality in long-term heart transplant recipients.

    Main Methods:

    • Retrospective analysis of 14 cardiac transplant explants from patients surviving over one year.
    • Histopathological examination to identify rejection and other pathological changes.

    Main Results:

    • 13 out of 14 long-term survivors showed advanced chronic rejection.
    • Obliterative arteritis, resembling atherosclerosis, was the most prominent vascular lesion.
    • Graft failure or death was attributed to chronic rejection in 11 patients; other causes included malignancy and embolism.

    Conclusions:

    • Advanced chronic rejection is a significant issue in long-term cardiac transplant survivors.
    • Obliterative arteritis is a key pathological finding, often leading to graft dysfunction.
    • Vascular lesions develop over years and are the main cause of late graft loss.
