“…In the studied goats the right coronary artery was single and was found to be less developed than the left coronary artery. Similar observations were made in ruminants (Nickel et al 1981;Barone 1996), reo deer (Frąckowiak et al 2007), Bactrian camel (Yuan et al 2009), European bison (Kupczyńska et al 2015) and Angora rabbit (Bahar et al 2007). However, in dog was described the additional right coronary artery (Bezuidenhout 2013) while in chinchilla the right coronary artery was absent Ozdemir et al (2008).…”

“…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.…”

“…Coronary vessels have been studied in domestic and wild ruminants including Angora and Akkamaran goats (Besoluk and Tipirdamaz 2001), roe deer (Capreolus capreolus Linnaeus, 1758) (Frąckowiak et al 2007), Bactrian camel (Camelus bactrianus Linnaeus, 1758) (Yuan et al 2009), one-humped camel (Camelus dromedarius Linnaeus, 1758) (Ghazi and Tadjalli 1993), European bison (Bison bonasus Linnaeus, 1758) (Kupczyńska et al 2015). However, the available literature provides little information on the topography of coronary arteries and their ramifications in the goats (Capra hircus Linnaeus, 1758) (Nickel et al 1981;Barone 1996;Besoluk and Tipirdamaz 2001). More information on its anatomy is needed.…”

Topography of coronary arteries and their ramifications in the goat

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.

“…In this study population of cats, only one individual lacked the main trunk of the LCA. A similar situation was reported in a single dog, suggesting independent origins of the ramus circumflexus sinister and the ramus interventricularis paraconalis (Noestelthaller et al., ; Barszcz et al., ). However, the absence of LCO and the arising of the LCA (then named as circumpulmonary coronary artery) from the RCA was described in three English bulldogs and a boxer (Buchanan, ).…”

Diagnosis and treatment of heart diseases due to changes in the coronary vascularization need a detailed knowledge on the morphology and possible variations of the aortic valves and coronary ostia. This study was performed to clarify details on morphology of these structures in domestic cats. The tricuspid aortic valve was examined in 65 domestic shorthair cats. The location of coronary ostia was determined either inferior to (26 and 20%, left and right coronary ostium - LCO and RCO), at (65 and 66%) or superior to the intercommissural line (9 and 14%). In 13 cats (20%), accessory ostia were found either for left, right or both coronary arteries (LCA and RCA). Their position varied between specimens. They were located beyond the main ostium, at its edge, or inside just below the edge. In one cat, no main trunk of the LCA was found. In one cat, two accessory ostia next to the RCO were observed. Coronary ostia in cats show anatomical variants and morphological anomalies. This study provides basic data useful for, for example, angiography performed for diagnosis of cardiac diseases and as a basis for surgical interventions.

“…The septal branch originating from the paraconal interventricular branch in all P. concolor individuals in the present study follows the pattern described in 60 % of the twenty domestic dogs analyzed by Noestelthaller et al (2007); and 62.5 % of the eight C. thous individuals dissected by Souza et al (2015b). The other possibilities describe the septal branch originating in the left coronary artery, in the aorta, or in the circumflex branch (Noestelthaller et al).…”

Morphol., 35(3):925-930, 2017. SUMMARY: This study described the anatomy of the coronary arteries and their main branches in Puma concolor. The hearts of six individuals of Puma concolor, were analyzed. The A. coronaria sinistra formed the ramus interventricularis paraconalis and the ramus circunflexus. A ramus septal was formed close to the origin of the ramus interventricularis paraconalis and yielded from six to eight ventricular branches. The circumflex branch originated from two to five atrial branches and from three to seven ventricular branches. The right coronary artery formed two to six atrial branches, and four to nine ventricular branches. In half of the individuals, an accessory coronary artery was identified as the first branch of the right coronary artery. In all individuals, the subsinusal interventricular branch originated in the right coronary artery. It could be inferred that coronary circulation in Puma concolor is balanced, as each coronary artery yielded an interventricular branch and there was no significant difference in the total number of branches that originated from each coronary artery. These findings are different from the descriptions of most carnivore species, and may aid a better understanding of the phylogenetic relationships and synapomorphies of carnivore coronary circulation, especially in the Felidae family.
