“…The subsinuous interventricular branch in boars was the continuation of the circumflex branch of the right coronary artery in 100% of the subjects, close to the results observed in swine, in 96.7% (VIEIRA et al, 2008) and in 100% of the samples (MOURA JUNIOR et al, 2008;BALLESTEROS, 2013). Nevertheless, in goats (MOURA JUNIOR et al, 2009) and in half-breed bovines (CORREIA-OLIVEIRA et al, 2013), this branch had its origin through the left circumflex branch.…”

The heart of a domestic swine is similar to that of a human regarding anatomy, blood perfusion, and distribution of nurturing arteries. In addition to the similarities, its low cost compared with other species is also one of the reasons these animals have been increasingly used in medical schools and in clinical, surgical, and pharmacological studies. Therefore, we aimed to identify the origin and distribution of the right and left coronary arteries of boars, emphasizing the configuration and macroscopic representativity of their branches while characterizing a possible dominance concerning the type of circulation and the potential use of this animal as an experimental model, hence boars are the ancestors of the domestic pigs. The left coronary artery has bifurcated into paraconal interventricular branch and circumflex branch; or it has trifurcated into paraconal interventricular branch, the oblique branch, and into the left circumflex branch. The right coronary artery has originated the marginal branches to the right ventricle and the right circumflex branch, which has branched out in the subsinuous interventricular branch. Anastomoses have stood out among the paraconal and subsinuous interventricular branches – where a right dominant coronary artery occurred – and between the right and left circumflex branches. We concluded that the morphology and the distribution of the coronary arteries of boars resemble those of a human and, thus, our results are useful for the conception of experimental hemodynamics and possible use as process models.

“…the meeting point between the interatrial, posterior (subsinuosus) interventricular and coronary sulci. Since then, other criteria have also been suggested: the lengths of arteries like the right coronary and left marginal branch (Baroldi & Scomazzoni, 1967); the layout of the arteries at the apex of the heart (James, 1961); the length of the paraconal interventricular artery (Ilia et al, 2001); and the number of branches to the ventricles (Vieira et al, 2008). Our aim was to investigate the various indicators suggested, in order to indicate which coronary artery is dominant in the hearts of dogs.…”

SUMMARY:In humans, the right coronary artery is dominant. However, we did not find any citations in the literature concerning anatomical indicators of dominance among dogs. We used 30 hearts from mongrels of both sexes, fixed in 10% formalin. The branches of the coronary arteries were dissected with special attention to the levels that were considered to be reference points. In 96.7%, the circumflex branch of the left coronary artery reached or went beyond the crux cordis. The subsinuosus interventricular artery, ended before reaching the apex in 21 cases, at the apex in five cases and after the apex in four cases. The paraconal interventricular artery, ended before reaching the apex in two cases, at the apex in 11 cases and after the apex in 17 cases. The region of the heart apex was irrigated by branches of the left coronary artery, through the paraconal interventricular branch or through both of the interventricular branches. The mean length and number of ventricular branches of the left coronary artery were greater than those of the right coronary artery. The subsinuosus interventricular branch is a branch of the circumflex branch of the left coronary artery. In the hearts of dogs, the left coronary artery is dominant. The dominance pattern in dogs is different from the dominance pattern in human that is mentioned in the specialized literature.

“…[9] In a study by Abuchaim DC et al [7] in 25 human hearts the most common form of coronary circulation was found to be the right dominant. In a study in swine by Vieira TH et al [10] the arterial pattern was found to be right dominance based on crux cordis and the subsinuosal interventricular branch. In a study on pigs by Sahni D et al [11] the RCA was found to be dominance in all hearts.…”

With the advent of coronary angiography, coronary artery diseases can be well combated; but with time sedentary life style and stress as our constant partner have kept coronary artery disease as one of the major causes of death. Revascularization procedures demand a sound knowledge of the course of coronary arteries and their branches, both normal and their quite common variations. In this regard, posterior inter-ventricular artery (PIVA) deserves a special importance; PIVA determines the coronary dominance depending on its parent artery. Dominance can be right, left or of balanced type. Balanced type means that PIVA is derived from both right & left coronary arteries. Circulation can occur when both the coronary arteries emit a branch in that area. These and other variations form a very important repertoire of information based on which coronary bypass surgery and angioplasty can be safely and effectively performed. The aim of this study therefore is to document the coronary dominance pattern in this East Godavari district of Andhra-Pradesh. 60 adult human hearts were collected from museum of Anatomy department during the tenure of 5 years (2009 to 2014) and were preserved in 10% formalin. The hearts were dissected carefully to observe the posterior inter-ventricular artery in the posterior inter-ventricular sulcus of each heart and dominance pattern was recorded. In our present study right dominance type was the commonest (46 out of 60) followed by left dominance (10 out of 60). Only 4 out of 60 were of the balanced type. Present study, though not of the only member of its kind will definitely add up to the already existing vast knowledge, based on which various diagnostic and therapeutic intervention of coronary artery diseases can be done effectively and safely.
