[Anatomical observations of the coronary artery vascularization in the guinea pigs (Cavia porcellus, L.)].
Through an examination of the subepicardial part of the heart in the guinea pig it was characterized a duality concerning to the origin and branching of the 2 coronary arteries which are represented by 4, and not by 2, aortic branches: the R. circumflexus sinister and the R. interventricularis paraconalis to the left coronary artery; the A. coronaria dextra and the R. coni arteriosi to the right coronary artery. The heart of the guinea pig was considered of the "left coronary pattern", but the whole characteristics of its arterial vascularization seem to be concerning to the "intermediate coronary pattern".
