Anomalous coronary artery, aortic dissection, and acute myocardial infarction.

The combination of acute coronary occlusion and aortic dissection because of involvement of one or other coronary vessels in the dissection flap is uncommon. Furthermore, the occurrence of an anomalous coronary artery and its involvement in acute myocardial infarction is even more uncommon. We describe a patient with acute myocardial infarction in whom an acute aortic dissection involved the ostium of an anomalous circumflex artery.
