Gross specimen of heart, myocardial infarction

Myocardial infarction. Sectioned heart showing an area of myocardial infarction (dark region, bottom left) in the left ventricle. The walls of this ventricle are also very enlarged, (ventricular hypertrophy) as compared with those of the right ventricle. Infarction usually results from a blockage in one of the two coronary arteries which provide the heart with its blood supply. Atherosclerosis of the coronary arteries is the cause in most cases. Plaques of atheroma (fatty substances) develop on the inner lining of the arteries restricting blood flow and encouraging the formation of clots. Damage to the heart muscle may be so severe that it leads to heart failure
