Acute Myocardial Infarct with Rupture

Acute Myocardial Infarct with Rupture •Transverse section positioned such that the anterior surface faces upward, and the view is of the superior surface of the section. •Note the irregular but distinct margins of the tan lesion which contrasts with the intact bright red myocardium. •The anterior and lateral walls are involved, sparing the posterior wall and interventricular septum. •Note the foci of hemorrage in the anterior wall where the infarct is transmural. These foci mark the tract (arrows) of a rupture through necrotic muscle and epicardium causing a lethal hemopericardium. (Description By:J. Hasson, M.D. ) (Image Contrib. by: A93-70 )
