“…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 paraconal interventricular branch in boars ranged from the paraconal interventricular groove to the cardiac apex, just as recorded in swine (MOURA JUNIOR et al, 2008;BALLESTEROS, 2014) and goats (MOURA JUNIOR et al, 2009). The left branch to the conus arteriosus was the first branch emerging to the right of the paraconal interventricular branch for the right ventricle in all of the samples, just as described in swine (SAHNI et al, 2008) and in humans (LIMA JÚNIOR et al, 1993).…”

“…The oblique branch of the left coronary artery, originated in the angle between the paraconal interventricular branch and the left circumflex branch, takes on different synonymies in the animals when the trifurcation of the left coronary artery is present. In swine, the oblique branch is described as the diagonal branch (MOURA JUNIOR et al, 2008) and as the diagonal artery (GÓMEZ; BALLESTEROS, 2014); in goats, it is described as the angular branch (MOURA JUNIOR et al, 2009); and still, it has been observed as the left marginal branch in rabbits (CORREIA-OLIVEIRA et al, 2014). For boars, the arterial denomination adopted is based on the oblique distribution in a dorsal-ventral and caudal organization.…”

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.

“…However, this variation was not found in the present study. The absence of signs of sexual dimorphism in coronary circulation was also reported by Moura Junior et al (2008) in pigs; Biasi et al, and Borelli in domestic cats;Biasi et al in domestic dogs;and Correia-Oliveira et al (2014a) in New Zealand rabbits.…”

Coronary Irrigation in Puma concolor (Carnivora: Felidae)

et al. 2017

Morphol., 35(3):925-930, 2017. SUMMARY: This study described the anatomy of the coronary arteries and their main branches in Puma concolor. The hearts of six individuals of Puma concolor, were analyzed. The A. coronaria sinistra formed the ramus interventricularis paraconalis and the ramus circunflexus. A ramus septal was formed close to the origin of the ramus interventricularis paraconalis and yielded from six to eight ventricular branches. The circumflex branch originated from two to five atrial branches and from three to seven ventricular branches. The right coronary artery formed two to six atrial branches, and four to nine ventricular branches. In half of the individuals, an accessory coronary artery was identified as the first branch of the right coronary artery. In all individuals, the subsinusal interventricular branch originated in the right coronary artery. It could be inferred that coronary circulation in Puma concolor is balanced, as each coronary artery yielded an interventricular branch and there was no significant difference in the total number of branches that originated from each coronary artery. These findings are different from the descriptions of most carnivore species, and may aid a better understanding of the phylogenetic relationships and synapomorphies of carnivore coronary circulation, especially in the Felidae family.

“…En una caso (2%), se observó a nivel de la bifurcación de las ramas interventricular paraconal y circunfleja, el origen de una tercera rama, formando una trifurcación arterial llamada rama diagonal, la cual se ha observado en corazones de cerdo con una frecuencia del 20% (Jordão et al, 1999) y en humanos en 45,3% (Moura Junior et al, 2008), 42,5% (Baptista et al, 1991) y 20% de los casos (Didio & Wakefield, 1975). La literatura relacionada con vascularización de aves, no menciona esta tercera rama, por lo que consideramos que en ninguno de ellos se encontró esta trifurcación en la arteria coronaria izquierda En cuanto a las anastomosis, según la clasificación realizada por Baroldi et al (1956), las uniones del mismo tronco coronario como homocoronario, y las que corresponden a dos troncos coronarios como anastomosis intercoronarias.…”

RESUMEN:Consideramos importante conocer la irrigación cardíaca del avestruz, debido a la poca investigación realizada; por lo cual se ha hecho un estudio descriptivo del patrón de distribución de las arterias coronarias y sus ramas ventriculares determinando la presencia, origen, longitud y distribución de ellas. Identificamos ramas ventriculares, las anastomosis, tipo de dominancia y realizamos una comparación del corazón del avestruz con mamíferos y humanos. Se estudiaron 50 corazones de avestruz, de la clase African Black, fueron preparados e inyectadas las coronarias con Látex Neopreno, con distinto color, y tratadas en formol al 10% por 10 a 12 días para la disección de las arterias y las ramas ventriculares. Las arterias coronarias del corazón de avestruz se originan en los senos aórticos derecho e izquierdo. La derecha se encuentra en un 98%, con una longitud promedio de 127,1 mm, recorre el surco coronario llegando al interventricular subsinuoso donde origina la rama interventricular subsinuosa en el 92%, además origina la rama del cono en un 98% y ramas ventriculares. La izquierda está presente en el 100%, presenta una longitud promedio de 40,19 mm, las ramas que se originan de ella, son la arteria interventricular paraconal en un 100%, la arteria circunfleja en un 100%, la arteria del cono en el 96%, una rama diagonal presente solo en el 2%, la arteria interventricular subsinuosa presente en un 8%, y además presenta ramas ventriculares. De las anastomosis, en el 6% no se encontró, con una un 42%, con dos un 22% con tres un 30%. La más frecuente es entre la arteria interventricular subsinuosa y la circunfleja presente en un 42,1%, La dominancia derecha, es un 56%, el balance en un 36%, y la dominancia izquierda solo en un 8%. Se observó que la irrigación sanguínea superficial presente en el corazón de avestruz, el tipo de dominancia y la gran cantidad de anastomosis superficiales, se semejan al corazón humano y de mamíferos.PALABRAS CLAVE: Arterias coronarias; Corazón; Avestruz. INTRODUCCIÓNEn el siglo II desde que Galeno describió los vasos que irrigan el corazón, en el hombre, estos han sido clásica-mente estudiados por diversos autores (
