Why Is the Septomarginal Trabecula Important?

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.

What is the purpose of the moderator band?

Function. The moderator band is important because it carries part of the right bundle branch of the atrioventricular bundle of the conduction system of the heart to the anterior papillary muscle.

What is the function of the papillary muscles?

Background— The papillary muscles (PMs) play an important role in normal cardiac function, helping to prevent leakage through the AV valves during systole. The nature of their attachment to the heart wall can affect the understanding of their function.
