Abstract
Congenital absence of the left circumflex artery is a rare coronary anomaly with few reported cases in literature. These patients are usually diagnosed incidentally when they undergo either a conventional or a computed tomography (CT) coronary angiography to rule out an underlying coronary artery disease. Coronary CT angiography is a useful noninvasive imaging modality which can be used to diagnose and confirm coronary anomalies reliably. In this article, we report a case of a 55-year-old female who was incidentally found to have a congenitally absent left circumflex artery after a workup was initiated for nonspecific chest pain.
