Sinus Venosus ASD with Eisenmenger Syndrome
Imaging findings
CT chest shows severe dilatation of the main pulmonary artery, right ventricular hypertrophy, and diastolic septal flattening. A superior sinus venosus atrial septal defect (ASD) is present, associated with anomalous pulmonary venous return of the right upper lobe vein into the SVC.
Key takeaways
A superior sinus venosus ASD is a congenital defect located near the SVC entry into the right atrium, almost always associated with partial anomalous pulmonary venous return. If left untreated, the chronic left-to-right shunt leads to severe pulmonary hypertension and shunt reversal (Eisenmenger syndrome).
