2. Defective at Base 



(a) Ventricular Septum Defective Below the Aorta. — The 

 large majority of interventricular septum defects are of the base 

 and of these the most frequent site of arrested development is 

 the posterior part of the anterior septum (Rokitansky). It has 

 been impossible to determine the percentage of defects in either 

 group because observers so frequently make no report as to the 

 portion of the base involved. This list and the one immediately 

 following, represent only a small part of the cases of defective 

 septum reported; for other cases see the clinical classification of 

 ventricular defects.
