“…In addition to presenting differences in origin and insertion, the number of insertions and shapes of the ST can differ between species. Although structural composition of the ST structure has a significant cardiac physiology and clinical importance, few papers precisely describe its histological composition 24 . Although some publications present the ST histological characterization, there is no detailed analysis of the quantification and distribution of the tissues which constitute the ST.…”

The moderator band (MB) is a common fibromuscular anatomical structure for the right ventricle of most animals. The histomorphometric and immunohistochemical analysis of the MBs of Egyptian Baladi cattle in relation to age was the aim of this study. Eighteen clinically healthy animals of both sexes were used for this study. The animals were divided into three groups depending on age, group I (N = 4, <1 year), group II (N = 8, 1–2 years) and group III (N = 6, 4–8 years). Cross sections of the MBs from all groups were stained with H&E, Masson's trichrome and anti‐connexin43 (Cx43) antibody for histological and immunohistochemical examinations. Also, measurements for the thickness of the endocardium of the MB as well as, the wall of its muscular artery were conducted. Bundles of Purkinje fibres (PFs) were identified peripherally in the endocardial layer and among the myocardial fibres in the core of each MB. The infiltration of endocardial adipocytes was the characteristic for MBs of old animals. All morphometric data showed a significant increase with the advancement of age. Immunohistochemical findings revealed the localization and distribution of Cx43 in the PFs and intercalated discs of all examined MBs. However, variation of Cx43 immunoreactivity was found among the groups depending on the age. On the basis of this study, this conclusion of different histomorphometry and Cx43 expression of the MBs in relation to age was drawn. These interesting findings provide further insight into age‐related physiological and pathological heart conditions.

The left ventricular false tendons (LVFTs ) are fibrous or fibromuscular bands crossing the left ventricle in human hearts ,they arise mainly from the ventricular septum to the free wall or to a papillary muscle .They are considered as normal anatomical variant with different numbers, location and type. LVFTs had been associated with many clinical studies and discussions regarding their function . Literatures were reviewed and their incidence ,morphology , histology and clinical correlation were discussed .This study was intended to evaluate the existence LVFTs in Basrah city , and to compare the findings with other data verified in literatures. A prospective autopsy study of the prevalence and morphology of LVFTs in 215 cadaveric human hearts was performed to estimate the number ,types and location .of these bands .10 out of 215 samples were undergo routine histopathological processing to obtain 4 micrometer thickness slides stained with hematoxylin and eosin and examined for histological characteristics . LVFTs of varying number, types and different attachment were recorded in 62 ( 28.8% ) of 215 adult human cadaveric hearts studied. A complete morphologic assessments were done. No significant differences was found regarding age or gender. , Majority of LVFTs are single , commonly between the ventricular septum and papillary muscle .Fibrous and fibro muscular type is predominant . In our community false tendons are frequent anatomic variants of normal human LV which may be identified at routine examination and should not be mistaken as pathologic structures such as flail chordae tendineae or thrombi, further radiological and clinical studies are suggested to ensure their role and function
