Anatomical terminology

The moderator band (also known as septomarginal trabecula) is a structure located in the right ventricle of the heart. The moderator band consists of conductive tissue branching off of the right bundle branch (within the ventricular septum) and wrapped in working cardiac muscle. Depending on the location of the anterior papillary muscle, the moderator band can range from readily apparent to difficult to discern.
