Abstract—Objective: Study of Septomarginal trabaculae in the ventricular chambers of the heart. Methods: The muscular ridges in the wall of ventricle is called Trabaculae carneae, a modified well-defined muscular band connecting like a bridge is known as moderator band. The length, breadth and number of these routinely existing moderator bands along with the additional bands were measured to compare the same in different cadaveric hearts. Results: Morphologically there was no significant pattern of variations were found in gross appearance of Septomarginal trabaculae, but some additional bands were recognized only in 2 hearts. Conclusion: Among 20 cadavers only 2 hearts were found with the additional bands. These additional bands may paly a significant role, if they support in carrying any additional conducting fibers or blood vessels to wall of the heart. Such contributions may play an important functional role to prevent any possible damage during myocardial ischemia.

Index Terms—Atrio-ventricular node, Sinuatrial node, Trabaculae carneae
