Septomarginal trabecula (heart, anatomy)

The septomarginal trabecula of the right ventricle, originally termed the moderator band because wrongly it was thought to limit the expansion of the chamber, is a muscular thickening extending from the interventricular septum to the base of the anterior papillary muscle. 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. At its septal attachment, it may be continuous with the supraventricular crest.
