Interventricular septum (or ventricular septum, or during development septum inferius), abbreviated IVS, is the stout wall separating the lower chambers (the ventricles) of the heart from one another.
The ventricular septum is directed obliquely backward and to the right, and is curved with the convexity toward the right ventricle: its margins correspond with the anterior and posterior longitudinal sulci.
