This photograph shows a cross-section of left and right ventricle. The left ventricle has ruptured through the free wall on the lower left, to cause a hemopericardium, cardiac tamponade, and death. Typically, this occurs a week or more into the clinical course of a myocardial infarct, because macrophages have begun to digest infarcted debris, whereas fibroblasts have not yet completed their task of laying down collagen.
