From: Anomalous pulmonary venous drainage: a pictorial essay with a CT focus
Anomalous right-sided pulmonary venous drainage with a superior sinus venosus defect. a Axial oblique CT MPR images show an anomalous right superior pulmonary vein (RSPV) draining into the superior vena cava/right atrium (SVC/RA) junction (white arrow) with an associated superior sinus venosus defect (SSVD, arrowhead) connecting the left atrium (LA) and right atrium (RA). b Post surgical repair the right superior pulmonary vein is now directed into the left atrium with closure of the SSVD. c Sagittal oblique CT images showing the SVC overriding a SSVD between the two atria. d Post surgery the SSVD has been repaired, the SVC (black arrow) drains directly into the right atrium
