Approximately 10 – 20% of heart transplant recipients will develop AMR. Standardized nomenclature has improved the diagnosis. This single center study revisits the risks of Class I and II DSA to C4D +IF and graft failure. C4d staining correlated better with graft failure in patients with DSA to only Class I or DSA to both Class I and II when compared to patients with DSA to Class II only. The role of DSA complement binding vs non_complement binding and its correlation with positive C4D IF staining remains to be elucidated.
