The coronary sinus (CS) refers to a collection of veins that join together to form a large blood vessel. This vein is located between the left atrium and the left ventricle of the heart.

The right coronary artery (RCA) arises further caudal, at the right aortic sinus. The RCA runs through the atrioventricular groove, encircling the tricuspid orifice, reciprocal to the LCX (Figure 4).
