A 12 month-old boy with tricuspid atresia underwent cardiac catheterization prior to undergoing a bidirectional Glenn shunt (BDG) procedure. A late-phase aortography image showed retrograde blood flow through the left superior vena cava, and selective coronary angiography revealed coronary sinus ostial atresia (CSOA). CSOA associated with single ventricle physiology is a potentially fatal condition because of the resultant disturbance of coronary circulation. An accurate evaluation of angiographic findings is necessary to identify CSOA.
