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
