This cross section reveals a large myocardial infarction involving the anterior left ventricular wall and septum. The color of the infarct is whitish-yellow. This is an example of pale (anemic) infarction.
MI involving LV anterior free wall and septum


There is yellowish discoloration of the myocardium. Note the anterior scar (arrowhead), indicative of old infarct. The myocardial hemorrhage at the Lt. ventricular lateral wall (asterisk) is due to ventricular rupture and was the acute cause of death in this patient (specimen is oriented with the posterior wall at the top).
