A heart, opened to show the posterior and lateral wall of the left ventricle. At the apex of the
specimen, you can see the posterior cusp of the mitral valve. The apical and lateral part of the left
ventricular wall is extremely thin, and bulges laterally as an aneurysm. At the margins of the
aneurysm, there is scarring in the myocardium. There are flecks of thrombus adherent to the wall
of the aneurysmal sac.
