Angiography to detect diversion of superior vena cava flow secondary to surgical repair of sinus venosus atrial septal defect

Redirecting superior vena cava [SVC] flow to left atrium [LA] is an iatrogenic complication following surgical repair of sinus venosus atrial septal defect. This case report describes a patient who continued to have hypoxia following the surgical repair of sinus venosus atrial septal defect. Transesophageal echocardiogram and right heart catheterization did not reveal any abnormality. Contrastangiography was performed from right internal jugular vein which confirmed flow from SVC to LA. Emergent corrective surgery then resulted in an uneventful hospital course
