Background— Sinus venosus atrial septal defect (SVASD) differs from secundum atrial septal defect by its atrial septal location and its association with anomalous pulmonary venous connection (APVC).

Background and Purpose— Sinus venosus defect is a rare cardiac abnormality, provoking an interatrial shunting outside the interatrial septum. Echographic diagnosis is difficult and may require ...

Superior sinus venosus atrial septal defect (SSV-ASD) is an uncommon abnormality of the interatrial septum that is usually accompanied by partial anomalous pulmonary venous drainage (PAPVD) of the ...

Sinus venosus atrial septal defect (SVASD) represents an uncommon subtype of atrial septal defects (ASDs), comprising approximately 5%–10% of cases (1). It is characterized by a defect located outside ...

Background: Superior sinus venosus atrial septal defect (SV-ASD) is an interatrial defect with partial anomalous pulmonary venous connection (PAPVC) draining into the right atrium. The principle for ...
