Transcatheter diagnosis and intervention for iatrogenic right-to-left shunts decades after surgical repair of partial anomalous pulmonary veins and an atrial septal defect.
A 57-year-old man presented with symptomatic right-to-left shunts decades after surgical closure of an atrial septal defect and partial anomalous pulmonary veins. Two sources of shunting were identified: a baffle leak from the right superior vena cava (RSVC) to the left atrium secondary to complete occlusion of the RSVC-to-right atrium connection and an acquired previously unpublished coronary sinus to the left atrial shunt secondary to inadvertent closure of the coronary sinus. The diagnosis and transcatheter management of these unusual right-to-left shunts are reported.
