Dual left anterior descending coronary artery and anomalous origin of left circumflex artery: a novel coronary anomaly revealed by CCTA

Abstract

In the rare coronary anomaly of Dual LAD, two segments of the vessel reside within the anterior interventricular sulcus. In our case, the short LAD originated from the Left Coronary Sinus (LCS), while the long LAD emerged from the Right Coronary Sinus (RCS). The LCx arose from the RCS, and the RCA displayed typical features. This anomaly was deemed incidental, prompting routine follow-up. It underscores the significance of integrating CCTA for a thorough assessment, offering crucial insights for patient management.
