Massive Calcification in Infarcted Myocardium

Abstract
14 cases with calcification within myocardial infarcts are reported. In 8 of the cases calcification was visible in life. Such calcification is most likely to be noted within the fibrosed myocardium of patients with large myocardial infarctions, who survive for 6 yrs. or more. It is most frequent in the region of the cardiac apex, and may be differentiated from pericardial calcification by its position within the heart muscle rather than on the contour of the silhouette. Calcification of infarcted myocardium, as in ventricular aneurysm, occurs in individuals with a predominant right coronary artery pattern, or with a balanced pattern, but is infrequent when the chief source of blood supply is from the left coronary artery. The clinical course in these patients is the same as in other patients with similar grades of infarction who have no calcification.
