The left ventricle shows aneurysmal dilatation of the anterior wall extending from the apex to a
point just beyond the halfway mark. The ventricular wall in this area is largely formed by fibrous
tissue. The endocardium shows fibrous thickening with a little adherent blood clot.
This man, aged 72, was found dead in bed. He had last been seen alive two days before
when he was reportedly in good health. At autopsy he showed bronchopneumonia. His heart
weighed 500 grams and there was complete atheromatous occlusion of the descending branch of
the left coronary artery at a point 2.5 cm from the origin of the vessel.
