Two slices of heart muscle showing an extensive infarct in the intra-ventricular septum. There are
areas of haemorrhage close to the endocardium of the left ventricle, with soft-looking grey-brown
areas related to these. The endocardium appears thickened. Towards one end of the infarct there
is scar tissue. The history of this patient is not known but the macroscopic appearance of the infarct
suggests that it is 2-3 days old.
