The authors report two cases selected from a series of 61 cases of coronary embolism observed over an 18 year period at the Cardiovascular Hospital (Lyon) out of 4,860 autopsies of adult patients who died of cardiovascular causes. These two cases underwent coronary angiography, the results of which correlated with the autopsy findings. The authors review the causes and clinical manifestations of coronary embolism and compare their results with previously reported data, to establish the radiological features of coronary embolism. They notice the regular appearance of obstruction due to embolism and underline the importance of the associated negative signs (normality of the rest of the coronary circulation, absence of collateral vessels...) which makes the angiographic diagnosis one of elimination.
