The moderator band (also known as septomarginal trabecula) is a band of cardiac muscle found in the right ventricle of the heart. It is well-marked in sheep and some other animals. It extends from the base of the anterior papillary muscle to the ventricular septum.
Where is the moderator band located?
The moderator band (MB, also known as the septomarginal trabecula) found in all human hearts is derived from the muscle band of the interventricular septum, begins below the septal end of the supraventricular crest, and runs toward the anterolateral wall of the ventricle [1].
What is the role of the septomarginal trabecula?
Its main function is to convey the right branch of the atrioventricular bundle of the conducting system. The septomarginal trabecula forms the anteroinferior border between the superior, smooth outflow tract of the ventricle and the trabeculated inflow tract.
