Key Features/Anatomical Relations

The right fibrous trigone connects the atrioventricular fibrous rings to the aortic ring.


The right fibrous trigone provides structural support to the atrioventricular and aortic valves and aids in the structural support of the membranous septum and serves as a direct attachment for the myocardium. It helps to separate the atria and ventricles and thus the electrical activities between the chambers by insulating the propagation of electrical impulses in a heartbeat.
