Endomyocardial biopsy and rejection

  • The endomyocardial biopsy (EMB) is an established clinical procedure used for obtaining myocardial tissue. It is typically performed under local / general anesthesia by passing a bioptome through the right internal jugular vein (more often vein access) across the tricuspid valve and into the right ventricle. The biopsy is considered adequate if at least 3 pieces of myocardium are present, 50% of which must be evaluable
  • Grade Cellular rejection:
    • Grade 0R- No evidence of cellular rejection
    • Grade 1R, mild – Focal perivascular or interstitial infiltrate without myocyte injury
    • Grade 2R, moderate – Two or more foci or dense infiltrate with myocyte injury
    • Grade 3 R, severe – Diffuse, dense, infiltrates with myocyte injury +/- edema+/- hemorrhage+/- vasculitis
  • Histopathologic changes of AMR, seen on light microscopy, are endothelial cell swelling, macrophages filling small vessel lumens and edema. Staining for the complement split product C4d is generally used to identify the presence of AMR by immunohistochemistry or immunofluorescence.
