Libelle of note
The vestibulum of the right atrium is the smooth-walled part that supports the hinges of the leaflets of the right atrioventricular valve (Ueda A, et al. 2013. Europace 15:728-734).
This isthmus is the inferior part of the septal surface of the right atrium. It extends from the wall of the inferior vena cava to the hinge of the inferior leaflet of the tricuspid valve (Saremi et al. 2008 Radiology 247:658-668).
The inferior pyramidal space is occupied by fibroadipose tissue of the inferior atrioventricular groove, which fills the space between the atrial floor of the atrioventricular nodal triangle and the crest of the muscular interventricular septum (Mori et al. 2015 Clin Anat 28:878-887).
