Tóm tắt

We report a case of 52-year-old male with chest pain where computed tomography coronary angiography (CTCA) demonstrated rare variant of dual left anterior descending artery (LAD) with anomalous origin and intramyocardial trans septal course of long LAD and normally arising shorter LAD from left main coronary artery terminating in proximal interventricular groove. We propose that this anatomy represents a new variant of dual LAD (Type VI-B). Our case highlights the role of CTCA in identifying such variant anatomy which can attribute to patients' symptoms and guide further management.
