The moderator band (also known as septomarginal trabecula[1]) is a band of cardiac muscle found in the right ventricle of the heart.[2][3][4] It is well-marked in sheep and some other animals, including humans. It extends from the base of the anterior papillary muscle of the tricuspid valve to the ventricular septum.[2]
