title: Dual left anterior descending artery arising from left circumflex artery with an intramyocardial coronary aneurysm.
abstract: Dual left anterior descending (LAD) artery is a rare anomaly conventionally classified into 4 types. We present a case of dual LAD artery in which the long LAD artery has arisen from the left circumflex (LCx) artery, a condition not previously included in the 4 defined types. Moreover, the long LAD artery specified here is associated with an intramyocardial coronary aneurysm. To our best knowledge, it is the first time such a coronary artery anomaly has been reported. This case suggests the important role of coronary computed tomography angiography (CTTA) for diagnosis and therapeutic planning for such an anomaly.
