[Classification of ventricular septal defects].

The hearts were examined from 125 patients with isolated ventricular septal defects (VSD) who had died at the age of 0-14 years before or without operation. One hundred twenty five heart showed 178 defects: 103 with isolated, 22 with multiple VSD. Five major defect types were identified: (1) perimembranous; (2) sinus; (3) central trabecular; (4) boundary muscular trabecular; (5) infundibular.

[The anatomy of the interventricular septum of the heart and the anatomical nomenclature].

With the aim to study interrelations of the interventricular septum (IVS) and systematization of their definitions, 151 preparations of hearts of persons died from causes having no connections with cardio-vascular diseases have been studied. The IVS consists of inflow and outflow septa. The inflow septum includes the sinusal (posterior) and trabecular septa, the outflow one--the anterior and conoid septa.
