text: In this type of<unk>  septal defect the common wall between the coronary<unk>  and the left atrium is not developed.
  Some patients with coronary<unk> <unk>  septal defects may also have a persistent left superior vena cava.
  A<unk><unk>  ASD is a type of<unk>  septum defect in which the defect in the septum involves the<unk>  inflow of either the superior vena cava or the inferior vena cava.
  It involves the superior portion of septum<unk> <unk>  ASD is posterior to the fossa ovalis
  A<unk><unk>  ASD that involves the superior vena cava makes up 2 to 3% of all interatrial communication. It is located at the junction of the superior vena cava and the right atrium. It is frequently associated with anomalous drainage of the right-sided pulmonary veins into the right atrium (instead of the normal drainage of the pulmonary veins into the left atrium).
