Figure 2 Histologic evidence of vasculitis. Endomyocardial biopsy specimen 1 month after heart transplantation in patient #10. A myocardial arteriole demonstrates evidence of vasculitis with intimal proliferation and edema almost obliterating the lumen (hematoxylin and eosin, x200). In addition to vasculitis, there was an evidence of ISHLT grade 3A parenchymal rejection (B). This patient demonstrated anterior myocardial perfusion abnormality in thallium perfusion scan. He was treated with increased immunosuppressive therapy with complete resolution of perfusion defect. This patient demonstrated normal coronary arteries at 34 months, when he died of a cerebrovascular accident.
