Learning objectives The Coronary Sinus (CS) is the largest cardiac venous structure. Anterior interventricular vein, great cardiac vein, left marginal vein and posterior vein and middle cardiac vein or posterior interventricular veins are the main branches of CS. The average width of the CS, which varies with width, it ranges from 5 mm to 16 mm at the level of the ostium. The thebesian valves, where the CS opens into the right atrium, protect the CS. Small valves may also be found...
Read more Background It is important to demonstrate CS anatomy as well as cardiac anatomy, as it is necessary for planning in electrophysiological procedures such as ablation, cardioplegia, stem cell therapy, and cardiac surgery [1-3].Echocardiography, computed tomography (CT) and magnetic resonance imaging are used for imaging. However, the most useful technique is CT angiography (CTA). The delay time is typically higher than in coronary artery CTA to provides acceptable venous enhancement. In daily practice, it perform venous studies with an additional delay of...

Read more Conclusion The CS has many variants and congenital anomalies.When radiological methods for the thoracic region are obtained in the appropriate protocol, the anatomy of the CS; variations and pathologies can be identified. When radiologists detect extensive CS, they should reveal accompanying abnormalities [1-6].
