The authors examinated 30 adult heart specimens and found that:(1)the longitudinal and transverse diameters of the orifices of coronary sinus are 17.79±4.66mm and 8.75±3.39mm respectively;(2)70.00% of the orifices or coronary sinus directs upwards of laterally and 30. 00%of them faces downwards;(3)the valves of the orifices appear in 5 forms,i.e.,crescent,semilunar, netlike,cribriform and crest;(4)the height and width of the valves are 5.31±4.18mm and 8.62±2.44mm respectively:(5)the length and the most narrow part of the coronary sinuses measure 31.33±10.22mm and 5.60±1.05mm respectively;(6)amgulation,stenosis and hypoplasia of the coronary sinus were also found;(7)73.33% of middle cardiac veins and 10.00% of small cardiac veins open near the orifice of coronary sinus.The clinical significance of these data for coronary sinus catheterization were also discussed.
