History
- Fully vaccinated
- Sudden death at home
- No other clinical abnormalities
Imaging
Haematology/Biochemistry
Gross Pathology
The following data and pictures were taken at post-mortem examination:
Cardiovascular system:
- Heart has a globoid shape
- Ventricular wall measurements:
- Interventricular septum; 12mm
- Right ventricular wall; 3mm
- Left ventricular wall; 10mm
- Pericardium is fatty, shiny and intact
No embolic thrombi were found in the abdominal aorta.
The other body systems were examined. No further abnormalities were found.
Histopathology
Samples were taken for histological examination (Stained with H and E):
- The cardiac myocytes are multifocally widely spaced and infiltrated by streams of spindle shaped cells (fibroblasts).
Some sections were stained with Massons Trichrome:
- This confirmed the presence of large, multifocal areas of fibrosis within the inner third of the myocardium and extending to the endocardial surface.
- Multifocally the fibrosis surrounds individual atrophied myocytes.
- There is mural thickening (smooth muscle hypertrophy) of the intramyocardial arteries.
