Therefore, knowledge about coronary anatomy remains key.<h4>Case summary</h4>A 5-day-old girl with prenatal diagnosis of Taussig-Bing anomaly (double outlet right ventricle with TGA and large subpulmonary ventricular septal defect) along with aortic arch hypoplasia and coarctation of the aorta underwent the arterial switch operation with closure of the ventricular septal defect and aortic arch repair. On preoperative echocardiography, the right (R) and left coronary artery (LCx) connected both to aortic sinus 1, suggesting 1RLCx coronary anatomy according to the LeiEuropean heart journal.
