Background and aim of the study: The human tricuspid valve is conventionally thought to have a fibrous annulus in the septal region. The study aim was to conduct morphological and histological analyses of the right atrioventricular junction (RAVJ), in particular to investigate the fibrous/collagenous content of this structure in the adult human heart. |
Results: There were no significant amounts of fibrous or collagenous structures along the free wall segment of the RAVJ. Muscular bars, measuring about 2-4 mm in diameter, were seen to run between the wall of the right ventricle and the RAVJ on its ventricular aspect. The relationship between the base of the tricuspid valve leaflet to the right atrial and right ventricular muscle head varied significantly within, and between, hearts. |
