Myocarditis is inflammation of the heart.

Idiopathic granulomatous myocarditis is dealt with in a separate article.

General

  • Uncommon.

Gross

  • Not apparent on gross.

Grossing:

  • Requires 10 sections to exclude;[1] sections should include right ventricle and left ventricle.
    • It is often missed with five.[2]

Microscopic

Features:

  • Inflammation.
  • Myocyte necrosis - disputed.[3]

Classification

Classified by the inflammatory cells present:[4]

  • Eosinophilic - hypersensitivity myocarditis - most common.
    • May be assoc. with peripheral blood eosinophilia.[5]
  • Lymphocytic - viral, autoimmune.
  • Granulomatous - infectious, idiopathic.
  • Neutrophilic.
  • Reperfusion (associated with myocardial infarction).

Images

  • Myocarditis (viral) - 1 (WC)

  • Myocarditis (viral) - 2 (WC)
