Malalignment of the Interventricular Septum with Atrioventricular Septal Defect: Its Implications Concerning Conduction Tissue Disposition

Summary

Malalignment of the interatrial and interventricular septal structures is rarely seen associated with atrioventricular septal defects. Such malalignment gives rise to an anomalous disposition of the conduction tissue specifically in regard to the siting of the atrioventricular node. Recognition of this abnormality prior to (or at) surgery is important if post-operative rhythm problems are to be avoided.
