Abnormal drainage of inferior vena cava to left atrium together with a partial abnormal pulmonary venous drainage to right atrium in the presence of atrial septal defect

摘要

The direct abnormal drainage of the inferior vena cava ( IVC ), while rare, is well‐recognized anomaly of systemic venous drainage. It has been reported both in isolation and in association with other cardiac defects. This is a case of an abnormal drainage of IVC into left atrium ( LA ) together with partial abnormal pulmonary venous drainage to the right atrium ( RA ) and atrium septal defect ( ASD ).
