The angiographic study of the parietal band (distal conus) is an important part of the investigation of certain cardiac malformations. In this presentation we have tried to determine the angiographic appearance of the normal parietal band as well as the angiographic aspect of certain conal malformations. Different anomalies of the parietal band may be distinguished: --1) An abnormally developped parietal band may be hypertrophied. 2) The parietal band may be underdevelopped. 3) A well developped parietal band may be in an abnormal position in relation to the interventricular septum. In determining an angiographic relationship between the parietal band, be it normal or abnormal, and the ventricular septal defect, we have tried to establish an angiographic classification of ventricular septal defects.
