Central fibrous body (heart, anatomy)

The right fibrous trigone is an extensive thickening of the most inferior part of the arch of the fibrous skeleton of the heart underlying the right posterior leaflet of the aortic valve. It is the largest thickening of the cardiac skeleton, and for this reason it is termed also the central fibrous body.

It is connected to numerous other components of the fibrous skeleton:

  • the posterior fila coronaria of the mitral valve annulus
  • both fila coronaria of the tricuspid valve annulus
  • the pars membanacea septi
  • the tendon of Todaro within the right atrium

Therefore, the right fibrous trigone forms a link between the aortic, mitral and tricuspid valves.
