(a, b, c) The 3D volume-rendered and (d, e) multiplanar reformat CT images of the heart showing coronary venous anatomy. The CS is located in the posterior atrioventricular groove and opens into the right atrium via the CS ostium. It is a continuation of the great cardiac vein and collects blood from the tributary veins of both ventricles and atria. The main ventricular venous tributaries include the anterior interventricular vein, lateral cardiac vein, posterior ventricular vein (not shown), middle cardiac vein (also known as the posterior interventricular vein) and small cardiac vein. (f) Axial CCT images demonstrating the valve of Thebesius. RA, right atrium; CS, coronary sinus; GCV, great cardiac vein; SCV, small cardiac vein; MCV/PIV, middle cardiac vein/posterior interventricular vein; LCV, lateral cardiac vein; AIV, anterior interventricular vein; LAD, left anterior descending artery; LM, left marginal artery; RCA, right coronary artery; PDA, posterior descending artery; AtV, atrial vein; TV, valve of Thebesius
