Overview
The ventricles of the heart are separated by two grooves, one of which, the anterior longitudinal sulcus (or anterior interventricular sulcus), is situated on the sternocostal surface of the heart, close to its left margin. The other groove separating the ventricles is the posterior interventricular sulcus.
