Atrial septation
Several techniques have been described for construction of interatrial baffles. When the left superior caval vein is unroofed, septation has been achieved using an obliquely positioned patch. In association with anomalous pulmonary venous return, some have used one patch for direction of the pulmonary veins to the systemic ventricle, and a second patch to complete atrial septation. When the orifice of the left superior caval vein is further from the midline, the coronary sinus has been reconstructed using a xenopericardial patch, again with a separate patch used to complete atrial septation.14-25
