Absence of Left Circumflex Artery: A Rare Congenital Disorder of Coronary Arteries

Abstract EN

Congenital absence of left circumflex artery is a rare occurrence and very few cases have been reported in literature.

It is a benign incidental finding; however some patients present with sudden onset chest pain mimicking acute coronary syndrome often resulting in detection of this rare anatomy on coronary angiography.

Coronary computed tomography angiography is a relatively new noninvasive imaging modality which can be used to confirm this suspicion and diagnose this unique morphology reliably.
