    Journal: Anat Anz; 1983; 154(2):133-44. PubMed ID: 6228160.
    Abstract:
    The configuration and morphological features of the coronary sinus (c.s.) were studied on 54 human adult hearts. The c.s. has on an average 36 mm in length and 9 mm in diameter. The most frequent is the cylindrical configuration (67%), then follows the so-called "wafer" form (19%) and the funnel shaped c.s. (13%). The valve of Vieussens was present in 78%, but well developed only in 6% of the cases. The classical opening of the middle and small cardiac veins into c.s. was remarked in 28%; for the rest the particular forms described in this work make themselves obvious. The large tributaries of c.s. are provided with ostial valves in a percentage of 41%. The form and dimensions of the Thebesius valve are very variable; it is absent in 9% of the cases. The Marshall's vein appears as an obturated cord in a proportion of 20%. In each case there was found on the surface of the c.s. a myocardial coat, consisting of two layers, which form a device having probably a constrictive function during the atrial systole.
