An Unreported Type of Coronary Artery Anomaly in Congenitally Corrected Transposition of Great Arteries

Congenitally corrected transposition of the great artery (ccTGA) is a rare congenital anomaly, accounting for 0.05% of congenital heart malformations (1). Most patients have associated cardiac anomalies, including ventricular septal defects, pulmonary stenosis, and systemic atrioventricular (AV) valve, conduction abnormality, and coronary anomalies (2). The identification of the coronary artery anatomy is essential in the preoperative evaluation for optimal surgical outcome (3) and can be evaluated using cardiac computed tomography (CT). Here, we describe a 51-year-old woman who had ccTGA with a new type of coronary artery anomaly detected on cardiac CT. This study was approved by the Institutional Review Board of our hospital. The requirement for patient informed consent was waived because of the retrospective nature of the study. CASE REPORT
