Ruptured intercalated discs
Ruptured intercalated discs of myocytes of the heart have two main causes:
- Microtome processing, thereby being a visual artifact, not needing reporting.
- Forceful myocardial contraction, at least in case of heart autopsy. This is mainly caused by ventricular fibrillation or electric shock,
If a lab often cause it as a visual artifact, it may be ignored in the report.[notes 2] If not, look for signs indicating forceful myocardial contraction, and thereby the mentioning of the findings in the report. Such signs are:
- Alternating bundles of hypercontracted myocytes with hyperdistended ones.
- Square-shaped myocardiocyte nuclei.
- Hyperdistended myocardiocytes with detached sarcomeres, and in proximity of hypercontracted myocardiocytes.
