One of the landmarks of the atrioventricular nodal triangle is formed by a fibrous continuation of the valve of the inferior vena cava, also known as the tendon of Todaro (Ho and Anderson 2000 J Cardiovasc Electrophysiol 11:83-89; Mori et al. 2015 Clin Anat 28:878-887).
|

The term skeleton fibrosum cordis is a general term for the fibrous scaffold supporting the valves and muscle fibres and electrically isolating the atria from the ventricles. It comprises a fibrous centre, two trigones, four anuli, three ligaments, the membranous septum and some related structures (Saremi et al. 2017 Radiographics 37:1330-1351 and Zimmerman 1966 Ann R Coll Surg Eng 39:348-366).
|

The right fibrous trigone together with the adjacent membranous septum and the insertion of the tendon of Todaro (currently listed as tendo spatii pyramidalis inferioris) form the so-called central fibrous body of the heart (Saremi et al. 2017 Radiographics 37:1330-1351).
|
| 15764 |
Fila coronaria are fibrous subendocardial cords, extensions of the fibrous trigones, forming about 75% of the anuli fibrosi (Kachlik et al. 2021 Bosn J Basic Med Sci 21:208-220).
|
| 15768 |
Clinical term for a fibrous area between the fibrous trigones, the anulus fibrosus sinister and the anulus aorticus, important in aortic valvular replacement surgery (Saremi et al. 2017 Radiographics 37:1330-1351).
|
| 15769 |
Fila coronaria are fibrous subendocardial cords, extensions of the fibrous trigones, forming about 75% of the anuli fibrosi (Kachlik et al. 2021 Bosn J Basic Med Sci 21:208-220).
|
| 15770 |
The anulus aorticus and anulus trunci pulmonalis are integrated parts of the fibrous skeleton of the heart, encircling the corresponding ostia, and forming a scaffold for the corresponding valves (Saremi et al. 2017 Radiographics 37:1330-1351; Kachlik et al. 2021 Bosn J Basic Med Sci 21:208-220).
|
| 15771 |
The tendo infundibuli is an inconstant fibrous band within the crista supraventricularis, arising at the level of the membranous part of the interventricular septum and extending cranially to connect with the infundibulum. It forms no real component of the fibrous skeleton of the heart (Saremi et al. 2017 Radiographics 37:1330-1351; Kachlik et al. 2021 Bosn J Basic Med Sci 21:208-220).
|
| 15772 |
The tendon of the conus is an inconstant fibrous band at the level of contact between the pulmonary trunk and the ascending aorta (Saremi et al. 2017 Radiographics 37:1330-1351).
