was planned for the next day when the patient suddenly collapsed.
Resuscitation efforts were unsuccessful.
- Macroscopically: collapsed dark area in the interior layer of
the left posterior wall with 90% stenosis of the proximal right
- Inner part of myocardium: degenerated muscle fibres. Loose connective
tissue with several macrophages partly loaded with lipofuscin. Small
clusters of lymphocytes. Wide, thin-walled blood vessels. Directly
under the endocardium, a rim of muscle fibres remain.
- The outer layer is intact with mildly hypertrophied muscle fibres.
Epicardium lacks noticeable changes.
