    AbstractAn 11-year-old boy with X-linked alpha-thalassaemia/ mental retardation symptom underwent gastrostomy. After the surgical procedure, insertion of a central venous (CV) catheter via the left subclavian vein was performed under X-ray radioscopy. However, the catheter did not move toward the right side of the heart shadow but descended caudally through the left side of the heart shadow. Transesophageal echocardiography (TEE) showed thickening of the coronary sinus, suggesting the existence of a persistent left superior vena cava (PLSVC). Contrast echocardiography using infusion of agitated saline into the CV catheter was performed. Microbubbles flowing from the coronary sinus into the right atrium were observed, and a diagnosis of PLSVC was made. TEE is useful for diagnosis of PLSVC when passage of a CV catheter via the left subclavian vein or left internal jugular vein is incorrect in a pediatric patient.
