Case report of coexisting transposition of the great arteries with supracardiac total anomalous pulmonary venous connection: focus on computed tomography features

Abstract Background The coexisting of transposition the great arteries (TGA) with total anomalous pulmonary venous connection (TAPVC) is one rare anomalies. incidence TAPVC and TGA unknown very few cases ever reported. Case presentation We reported a case 13-month-old female toddler history cyanosis. Echocardiography revealed atrioventricular ambiguity atresia, all PVs drain into innominate vein via vertical (VV), ostium secundum atrial septal defect (ASD) ventricular (VSD) were observed. CT scan confirmed co-occurrence TAPVC. All four confluence behind small left atrium (LA), drains an ascending lateral large VV, coursing to without any PV access LA. superior vena cava, right ventricle (RV) dilated. RV origin aortic root. aorta continues on side, arterial aberrant artery at level arch. Main originates from LV appears atretic only artery. Large ASD VSD identified. Conclusions are combination should be suspected in mild-cyanotic levocardia situs solitus. angiography modalities choice characterize vasculature
