This case features the classic association of an atrial septal defect (ASD), upper sinus venosus type, with partial anomalous pulmonary venous return (PAPVR) into superior vena cava.
This patient had a cardiac ultrasound examination beforehand which found: ASD septum secundum and most likely sinus venosus as well, with a gap of 26mm. No posterior bank, hence surgical indication. The cardiologist was then looking for associated PAPVR.
No posterior bank between both atria, SVC and the PAPVR: this means that percutaneous closure would most likely fail, hence the surgical indication.
