Gross processing
Heart specimens are generally not inked.
Basic microscopic screening
Generally check for signs of myocardial infarction. Further information: Autopsy of myocardial infarction
(For myocardial biopsies:
- Evaluate specimen adequacy. An adequate amount of tissue is generally 4 fragments (or 3 if each fragment is high quality).
- Evaluate on H&E, trichome stain (to better evaluate any fibrosis) and Congo red (to exclude any amyloid).)
Common findings
Myocardial lipofuscin reflects normal ageing rather than any cardiac pathology,[1] and does not need mentioning in the elderly.
Ruptured intercalated discs. Further information: Ruptured intercalated discs
Fibrosis. Further information: Myocardial fibrosis
Rectangular "Boxcar" nuclei: Look for myocardial hypertrophy, especially when enlarged. Otherwise, ruptured intercalated discs can cause square shaped nuclei.
Other conditions to look for
