Abstract

A 29-year-old African American man presented with atypical chest pain. Coronary computed tomographic angiography (64-slice) showed a previously not described variant of dual (duplicated) left anterior descending artery (LAD). Duplication of LAD is a rare anomaly and has been categorized into 4 angiographic subtypes based on the origin, course, and termination of the short and long LAD. Our case is unique in that, unlike previous subtypes, the short LAD originates independently from the left coronary sinus and that the long LAD arises from the right coronary sinus and has an intramyocardial course before reaching the distal interventricular groove. It can be, thus, considered a new variant of dual LAD (type V). © 2010 Society of Cardiovascular Computed Tomography.
