“…The location of the coronary ostia was symmetrical in only 44/91 dogs (48%). In contrast, similar observations showed symmetrical positions in most cats (50/65; 77%) ( 3 ), horses (45/70; 64%) ( 36 ), and sheep (42/58; 72%) ( 35 ). Symmetry in a minority of subjects was also observed in pigs: only 27% of these animals had such coronary ostia (16/60) ( 35 ).…”

“…The location of the structures was assessed using the method proposed by Cavalcanti et al . ( 14 ), which has been applied both in human and veterinary medicine in domestic cats ( 3 ), sheep and swine ( 35 ), and equines ( 36 ). In the present study, the ostia was most commonly located below the intercommissural line (type I).…”

“…Both coronary arteries demonstrated three types of ostia position in relation to the intercommissural lines, i.e . type I – below the intercommissural line, type II – on the intercommissural line, and type III – above the intercommissural line ( 3 , 14 , 35 , 36 ).…”

“…In veterinary medicine, studies on aortic valve structure and the topography and morphometry of ostia have been carried out in various mammalian species, such as equines ( 36 ), sheep and swine ( 35 ), donkeys ( 34 ), domestic cats ( 3 , 4 ), cattle ( 19 , 20 ), European bison ( 6 ), and chickens ( 9 ). The most commonly observed differences include the location of the ostia in the area of specific aortic sinuses, the symmetry of the ostia, the presence of accessory ostia, and variability in the structure of the common trunk of coronary arteries.…”

Introduction The purpose of this study was to perform a morphometric examination of the coronary ostia, including their location in the area of the aortic sinuses, and to describe variations in ostia structure in the domestic dog. Material and Methods The study was conducted on the hearts of 91 pedigree dogs of both sexes, aged 1 to 18 years (median 9 years), with a body weight from 1.2 to 65 kg (median 20.7 kg). Morphometric examinations of the coronary ostia were performed in the studied individuals, and the location of the structures in relation to the intercommissural lines was determined. Results Three types of location of the coronary ostia were distinguished, i.e. below the intercommissural line (type I), on the intercommissural line (type II), and above the intercommissural line (type III). In the studied dogs, the most common location of the ostia was type I – found in the left coronary artery of 74/91 dogs (81%) and in the right coronary artery of 42/91 dogs (46%). Morphological variations were shown in 36/91 dogs (40%) in the structure of the coronary ostia, including the presence of accessory ostia. The most common variation was the presence of an accessory ostium near the ostium of the right coronary artery, which was found in 28/91 dogs (31%). Conclusion The results may be useful in developing standards for procedures to replace the whole or part of the aortic valve and repair the coronary artery.
