“…During exercise, approximately 10% of the blood is ejected during systole and distributed through the coronary arteries (Schummer et al, 1981). This functional significance has stimulated anatomical studies on the coronary arteries and their main branches in Canis lupus familiaris (Andretto et al, 1973; Biasi et al, 2013; Büll & Martins, 2002; Donald & Essex, 1954; Moore, 1930; Oliveira et al, 2011; Pianetto, 1939), Felis catus (Biasi et al, 2012; Borelli, 2014; Monfared et al, 2013), Panthera tigris (Pérez & Lima, 2007), Felis silvestris , Vulpes vulpes (Hadžiselimović et al, 1974), Panthera leo (Schiller, 1957), Panthera pardus , Arctonix collaris (Zhang et al, 2008), Mustela nigripes (Truex et al, 1974), Mustela putorius (Evans & An, 2014), Arctocephalus australis (Pérez et al, 2008), and Pusa hispida (Smodlaka et al, 2009). Among domesticated species, coronary artery anomalies are more commonly described in dogs and cattle, but they are not always associated with significant dysfunctions as in humans (Scansen, 2017).…”
