title: [Features of the contour of the inner surface of the cardiac ventricles and Thebesius-Vieussens vessels].
abstract: Using certain morphological methods, relief peculiarities of the cardiac ventricle chambers, form and extent of the intertrabecular spaces, connections with the myocardial blood bed have been studied in 92 human hearts. Foramina, fissurae and excavations on the internal surface of the ventricles are the beginnings of the intertrabecular spaces, in their deep parts elements of the microcirculatory blood bed of the myocardium have openings. As demonstrate serial sections, there are not any immediate anastomoses between the myocardial arteries, veins and the intertrabecular spaces. This fact does not confirm the existing opinion that the smallest cardiac veins (Viessen-Thebesian vessels) belong to the arterio-venous anastomoses. A propose is made to use the term "the smallest cardiac veins" only to the veins that directly open into the auricular chambers.
