Primary dissecting aneurysm of the right coronary artery

Coronary arterial dissection is extremely rare. Such dissections have been reported to occur secondary to atherosclerosis, trauma, the postpartum state, and cystic medial necrosis and to be iatrogenically induced during catheterization. The clinical picture of coronary arterial dissection is usually sudded death. A review of the literature reveals that our case is the second in which a spontaneous coronary arterial dissection has been diagnosed during life and documented by coronary arteriographic studies. This report describes a 31-year-old man who presented with an acute inferior myocardial infarction. Coronary arteriographic studies demonstrated a dissection of the right coronary artery.
