Following a myocardial infarct one year previously, this 59 year old man developed angina pectoris. He was admitted to hospital after a bout of severe chest pain and died three days later.
The heart has been sliced to display the left ventricle. At the lower left of the specimen, in the antero-septal region, near the apex of the left ventricle, is an irregular yellow necrotic area 4 cm in length. A thin zone of congestion surrounds this area and a mural thrombus is adherent to the overlying endocardium. The left ventricle is hypertrophied. This is an antero-septal infarct.
