“…The number of these muscles in our study was one-four, only one had two heads. Literature documented the number of the anterior papillary muscles to be one [5,15,21,46,58], one-two [2], one-three [22,34] or one-four [29]. This number was one in each sample examined in this study, and the muscle possessed no heads or bellies, contrary to some literature [21,29,35,46].…”

“…There are two different views on determining the number of the cusps of the right atrioventricular valve. Some literature [12,15,34,55,58,59,65] indicated that the right atrioventricular valve possesses anterior, septal and posterior cusps, with the posterior one displaying sectional nature. Yet, other reports [5,26,29,43,60,[64][65][66] showed that the anterior and posterior cusps may occasionally fuse.…”

Morphology of the atrioventricular valves and the intraventricular related structures were observed and the findings were compared broadly to the literature, in the 7 hearts of the wild pigs (Sus scrofa) by applying macroscopic and microscopic techniques. In all hearts examinated, the tricuspid and mitral valves were precise, composing three and two cusps resepectively. The papillary muscles observed in mammalian heart in general were found in both the ventricles, additionaly there were small unnamed papillary muscles in the left ventricle of the three samples. The septomarginal trabecula and false chords were present in the right ventricles, microscopically possessing myocardial fibers, connective tissue and purkinje cells while the false chords were located in all the left ventricles but the septomarginal trabecula was found in the three samples only. Both the connective tissue and purkinje cells were present in these two structures but the myocardial fibers. Presence of the myocardial fibers in the right ventricle may have an effect on the ventricle geometry.

“…Sakon et al [57] found that approximately half of the tricuspid valves had multiple scallops localized in the inferior/posterior leaflet. Conversely, Kujur et al [58] found three leaflets in all 42 formalin-fixed adult human hearts dissected. Recently, Hahn et al [59] introduced a novel nomenclature system for the description of the number of tricuspid leaflets and for determining the relative incidence of each morphological type.…”

Even though the tricuspid valve is no longer “forgotten”, it still remains poorly understood. In this review, we focus on some controversial and still unclear aspects of tricuspid anatomy as illustrated by noninvasive imaging techniques. In particular, we discuss the anatomical architecture of the so-called tricuspid annulus with its two components (i.e., the mural and the septal annulus), emphasizing the absence of any fibrous “ring” around the right atrioventricular junction. Then we discussed the extreme variability in number and size of leaflets (from two to six), highlighting the peculiarities of the septal leaflet as part of the septal atrioventricular junction (crux cordis). Finally, we describe the similarities and differences between the tricuspid and mitral valve, suggesting a novel terminology for tricuspid leaflets.
