The heart is sectioned to display both the left and right ventricular cavities. There is an extensive
area of myocardial infarction involving the posterolateral wall of the left ventricle, extending up to
involve the left atrium and auricular appendage. Sectioning of the ventricle in this area shows that
the infarction is transmural. There is also a mild fibrinous pericarditis extending from the anterior
wall of the left ventricle to the posterior wall of the right ventricle.
The patient was an elderly diabetic and the myocardial infarction had occurred three
weeks prior to death
