[Sources of vascularization of the interventricular septum and septal papillary muscles in various types of blood supply in humans].

Using the preparation method, roentgenoangiography by means of contrast lead mass and polychromic injection of the coronary vessels, vascularization of the interventricular septum (IVS) and the septal papillary muscles (SPM) has been studied on 49 preparations of human hearts (age 19-89) The data are presented on distribution pattern of the IVS and SPM of the coronary arteries branches at various types of the cardiac blood supply. Angioarchitectonics of the IVS is described along its whole length. Topographic peculiarities of the SPM blood supply on dependence of their position on the IVS are noted.
