ABSTRACT
Selective phlebographies of the azygos vein and of the internal mammary veins have shown the existence of spiral movements of the hematic currents coming from the venae cavae into the RAA and toward the tricuspidal ostium. Indeed, the contrasted blood coming from the venae cavae, rather than becoming immediately assimilated with the noncontrasted endoatrial blood, appears lo be directed to fill the RAA selectively. Subsequently, the hematic current is pushed by the energetic, contraction of the RAA towards the tricuspidal ostium below, describing a suggestive irregular spiral image, which is partly visible also in the afflux chamber of the right ventricle. The interpretative hypotheses of the genesis and meaning of these ‘spiral’ currents is shown, particularly in relation to the dynamics of the RAA. The findings make clear the active function of the RAA; because of its strong and differentiated muscular structure and its close relations with the sinoatrial node, the RAA appears suggestively interpretable as the true motor in the dynamics of the right atrium.
