[Angiogenesis and heart vasculogenesis]

The first sketch of coronary arterial vascularization settles down in human embryos of the stadium 14 of O'Rahilly starting from endothelial islands that contain dense eritoblastes formations that don't present connection with the cavity ventricular willing subepicardial. The presence of this primitive plexus is in intimate dependence with the Jelly acellular of Davies and not with the increase and structuring of the myocardium. Each coronary artery is developed starting from two anlages: one distal that makes it starting from the net subepicardial, and another proximal coming from the evagination of the endocardium of the breasts Valsalva. The final period of the process of coalition of both anlages, and consequently the coronary vascular pattern's determination, it is established in the stadium 20 of O'Rahilly.
