“…It is generally assumed that coronary artery anomalies are relatively rare, occurring in about 1% of patients. In most cases, they affect the LCA ( 28 , 40 ). However, this is not confirmed by findings from veterinary medicine.…”

“…Morphological variations related to the location of coronary ostia may lead to myocardial ischaemia, infarction, and sudden death. It should be emphasised that the presence of accessory coronary vessels or a single coronary artery (SCA) are recognised as rare anomalies in about 1% of patients ( 15 , 28 , 40 ). Variations associated with the location of coronary ostia were found in 0.3% of cadavers in a necropsy series and in 1.6% of patients undergoing coronary angiography ( 27 ).…”

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.

“…A study concluded that it is not always easy to differentiate dual RCA from high splitting of PLV branch. In reality it is a split RCA, wrongly labelled as dual RCA [ 6 ]. Another study has shown that during coronary angiography, right anterior oblique (RAO) view can help in differentiating the dual RCA from the large right ventricular artery [ 7 ].…”

There is a significant variation in the mapping of epicardial coronary arteries. This variation may present as different anomalies. These anomalies are usually asymptomatic and can be present at birth. Some might become symptomatic during adulthood and subsequently, result in sudden death. The anomalies, in turn, present a challenge to clinicians during therapeutic intervention. Therefore, there is a growing need to have knowledge about the various forms of the coronary artery anomalies. In our case report, we present the case of a patient who had one such anomaly and provide a hint at one strategy that was used to tackle the challenge.
