[Standardization in the evaluation of acute rejection in heart transplantation]

The author presents a review of acute rejection classifications from the point of view of histology. She examines the relationship between conventional and cyclosporin immunosuppression and the differences in clinical practice and morphology. The article includes Stanford, Texas, Hannover and Brigham's classifications. Because of the inconsistent use of classifications in endomyocardial biopsy evaluation, the Society for Heart Transplantation has developed a standard biopsy classification system also presented in the article.
