Coronary arteriovenous fistula (CVAF) is usually an asymptomatic, incidental finding observed in 0.1%–0.2% of patients undergoing coronary angiography. Myocardial infarction (MI) secondary to a CVAF has been rarely reported. We herein describe a case of a young male presenting with acute inferior wall MI without any underlying cardiovascular risk factors and normal coronaries except for the presence of a small CVAF arising from the proximal right coronary artery. This report deliberates on the possibility of this fistula being an incidental finding as a bystander or as a culprit in this special clinical scenario, after careful exclusion of other possible nonatherosclerotic etiologies.
