Resumo: | 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. |

Tendo um menor custo para sua aquisição quando comparado a outras espécies, e dada sua similaridade apresentada, o uso desses animais nas escolas de medicina, em estudos clínicos, cirúrgicos e farmacológicos tem aumentado. Portanto, objetivou-se identificar a origem e distribuição das artérias coronárias direita e esquerda de javalis com ênfase na configuração e representatividade macroscópica dos ramos derivados das mesmas, caracterizando uma possível dominância quanto ao tipo de circulação e o potencial uso deste suídeo como modelo experimental, visto que são considerados ancestrais dos suínos domésticos. A artéria coronária esquerda bifurcou-se e deu origem aos ramos interventricular paraconal e circunflexo esquerdo, ou trifurcouse nos ramos interventricular paraconal, oblíquo e circunflexo esquerdo. Já a artéria coronária direita deu origem aos ramos marginal para o ventrículo direito e circunflexo direito que, por sua vez, ramificou-se no ramo interventricular subsinuoso. Foram evidenciadas anastomoses entre os ramos interventriculares paraconal e subsinuoso, e entre os ramos circunflexos direito e esquerdo e, conforme tal origem do ramo interventricular subsinuoso, a forma de dominância coronariana foi predominantemente direita. Conclui-se que a morfologia e distribuição das artérias coronárias de javalis se assemelham à do homem e, desse modo, nossos resultados são úteis para sua concepção da hemodinâmica experimental, e possível utilização como modelos processuais.Universidade de São Paulo.

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. |
