Iatrogenic diversion of IVC to left atrium after surgical closure of ASD

Abstract

Iatrogenic diversion of the inferior vena cava (IVC) to the left atrium during surgical closure of an atrial septal defect (ASD) is a very rare complication in the era of cardiopulmonary bypass. The eustachian valve could be mistaken for the margin of the ASD. We report a case with this complication after closure of a sinus venosus ASD of the IVC type.
