Abstract
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.
Highlights
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)
The paraconal interventricular branch was a strong vessel which was branched from the left coronary artery
There were a stronger paraconal interventricular branch and a weaker circumflex branch. This type of trunk morphology has 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, 2016b) and European bison (Kupczyńska et al 2015)
Summary
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). 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). The similarity of organ size between goats and humans makes these animals widely used. They are used in human medicine in research such as cardiac, orthopedic, model for infectious diseases or many others (Shiraishi et al 2012; Chen et al 2015; Zhang et al 2015; Lukovsky-Akhsanov et al 2016; Du et al 2018; Vandersteene et al 2018)
