[Sources of the vascularization of the human interatrial septum of the heart with different variants of the atrial blood supply].
Angiograms of 110 preparations of the human hearts at various ages have been studied. In order to reveal vessels of the coronary bed, roentgen contrast lead mass has been used. Peculiarities of vascularization have been described in all parts of the interatrial septum and in the fossa ovalis area at various variants of branching of the atrial vessels: right coronary, left coronary and even. With age, in the fossa ovalis area certain decrease in the number of the blood vessels is observed and the network they form becomes less dense. In the interatrial septum its middle part and the fossa ovalis area are the regions which contain the least amount of vessels. In the antero-inferior part of this septum a comparatively dense vascular network is revealed.
