Due to our interest in clarifying the congenic problems at the origin of the coronary arteries, we have published in the early 70´s a theory (Borges et al., 1974) in which the coronary arteries would be the last pair of aortic arches that, at the beginning of the embryogenesis, would be connected with the previous arch, trunk of the lung's artery through a duct which we named "ductus coronarius".
