A 9-month-old baby girl, with a history of a “heart murmur” for the past 6 months, was admitted for diagnosis and treatment. Physical examination revealed a cyanosis, an acropachy, and a heart murmur (level 3/6) on the left side of the sternum. An echocardiography showed a Tetralogy of Fallot, a patent ductus arteriosus (PDA), a persistent left superior vena cava (PLSVC) and a suspected double-outlet right ventricle (DORV). Cardiac CT examination was requested to specify the diagnosis of a DORV.
