“…They are also a known entity in humans but having only little clinical significance (Angelini 1989). In our study, the proportion of lynx with an accessory coronary orifice or other variation of its formation was similar to that of domestic cats, 19% and 20%, respectively (Barszcz et al 2016). In domestic cats, additional ostia were most commonly found in conjunction with the right coronary ostia, whereas in the present study they were located in the left.…”

“…However, excessive diffuse networks of ventricular bands have been associated with heart failure and death in cats (Liu et al 1982;Robinson and Robinson 2015). The presence of accessory coronary orifices has been reported in other mammalian species, including the domestic, shorthair cat (Barszcz et al 2016) and the Syrian hamster (Durán et al 2007). They are also a known entity in humans but having only little clinical significance (Angelini 1989).…”

“…In domestic cats, additional ostia were most commonly found in conjunction with the right coronary ostia, whereas in the present study they were located in the left. The differences in the locations of the coronary orifices or the presence of additional orifice in other mammalian species and the possible effect on the coronary circulation have been discussed extensively by Barszcz et al (2016).…”

Anatomical variations and pathological changes in the hearts of free-ranging Eurasian lynx (Lynx lynx) in Finland

The Eurasian lynx (Lynx lynx) despite the wide distribution has fragmented populations with possibly decreased genetic variability. Reports from Central Europe have raised cardiac health as possible risk factor for lynx populations. The knowledge on normal anatomic variations of lynx heart is crucial to assess emerging pathological or hereditary disorders. The aim of this study was to give a detailed description of the cardiac anatomy and circulation of the Eurasian lynx and to report the cardiac health of the lynx in Finland. The cardiac anatomy and pathology were studied post mortem from 63 legally hunted lynx. In general, the cardiac anatomy of Eurasian lynx corresponded with that described for other felids. In the ventricles, varying number of thin ventricular bands was a common feature and their histological appearance was characterized by a fibromuscular pattern. The size of the heart varied between males and females, but the relative size was similar to that described for most domesticated carnivores. No marked pathologic lesions were observed in the lynx hearts. Fibrosis was observed in 56% of the hearts, but it was focal and mild in degree and unlikely to affect cardiac function or to have clinical significance. In conclusion, the cardiac health of the Finnish Eurasian lynx population is good with no signs of heritable cardiac disorders. Furthermore, we were able to give a detailed anatomic description of the lynx heart, which can serve as a reference for further epidemiological investigations on cardiac diseases in lynx populations.

“…There were a stronger paraconal interventricular branch and a weaker circumflex branch. This type of trunk morphology has also been described in ruminants (Nickel et al 1981;Barone 1996), roe deer (Frąckowiak et al 2007), Bactrian camel (Yuan et al 2009), donkey (Ozgel et al 2004), porcupine (Atalar et al 2003), ringed seal (Smodlaka et al 2008), chinchilla (Ozdemir et al 2008), cat (Barszcz et al 2014(Barszcz et al , 2016b and European bison (Kupczyńska et al 2015). Whereas Bahar et al (2007) reported that in the Angora rabbit, the common trunk of the left coronary artery was divided into the paraconal interventricular branch, the circumflex branch and the proximal branch of the left atrium.…”

The aim of this study was to investigate the morphology of the coronary arteries of the goat's heart. The study was carried out on 36 hearts of adult females dairy goats, belonging to two breeds, aged 7-12 years, with an average body weight of 37 kg. A distinct view of coronary arteries and their branches was obtained by filling them with dyed synthetic latex (LBS 3060) or Batson's No. 17. In all studied goats the common trunk of the left coronary artery was divided into the interventricular paraconal branch and the circumflex branch. The branch of the interventricular septum originated in the interventricular paraconal branch. In 25 individuals (69%) the circumflex branch ended with small ramifications on the atrial surface of the heart. In 11 individuals (31%), the vessel extended in the subsinuosal interventricular groove into the subsinuosal interventricular branch. The right coronary artery was less developed than the left coronary artery. In 35 individuals (97%) the right coronary artery ended with small ramifications on the atrial surface of the heart. In one goat (3%) the vessel reached the subsinuosal interventricular groove and extended into the subsinuosal interventricular branch.

The aim of the study was to investigate the morphology and morphometry of ramifications of the aortic arch in domestic shorthair cats in relation to the sex of the animals. The morphological study was performed on 61 hearts of adult domestic shorthair cats of both sexes, preserved in the 10% solution of formalin. Measurements of the area of openings of basic branches and distances between them were performed. In cats we can observe a double type of direct ramification of the aortic arch: the brachiocephalic trunk and the left subclavian artery. In all studied cases, the surface area of the ostium of the brachiocephalic trunk (SABT) was greater 4.94 ± 1.35 mm2 than the surface area of the ostium of the left subclavian artery (SALSA) 2.38 ± 0.88 mm2. The average difference between the opening area of the above vessels (r) amounted to 2.56 mm2. In the studied group of cats, the distance between the openings (d) varied between 0.5 and 4.37 mm. In the post hoc comparison of the mean values no statistically significant differences were found between the population of males and females. Fundamental changes in the structure of openings were found in two females. The first one concerned a secondary division of the brachiocephalic trunk opening and the second one – a secondary division of the opening of the left subclavian artery in the area of their parting from the aortic arch. CT angiography or MRI angiography is the method of choice for diagnosis of vascular disorders or malformations. The knowledge of the aortic arch morphology in various species of animals is a prerequisite for a correct assessment of the results of imaging tests.
