The coronary sinus arises upon the posterior aspect of the heart between the left atrium, and left ventricle. [1] The coronary sinus commences at the union of the great cardiac vein, and the oblique vein of the left atrium.

Nov 3, 2023 · The coronary sinus is the largest cardiac venous structure. It arises from the confluence of the oblique vein (of Marshall) of left atrium and the great cardiac vein. The sinus then courses for about 2 or 3 cm within the inferior atrioventricular groove, between the left atrium and left ventricle.

Nov 17, 2022 · The coronary sinus describes a major coronary vein located in the rear section of the heart. Many smaller cardiac veins connect to it to make it the largest vein of the heart.

The coronary sinus (CS) is the cardiac venous system that begins at its ostium in the right atrium and ends at the origin of the great cardiac vein.

Oct 27, 2024 · The coronary sinus is the largest cardiac venous structure. It returns the majority of the blood supply for the left ventricle to the right atrium. The coronary sinus courses along the posterior wall of the left atrium into the left atrioventricular groove. It …

Jan 12, 2024 · The coronary sinus is a large vein that returns deoxygenated blood from the heart muscle to the right side of the heart so that it can be replenished with oxygen. The coronary sinus is located on the heart’s posterior (behind) surface …

The coronary sinus is a large venous structure in the heart that collects deoxygenated blood from the heart’s myocardium. [7] It serves as the main drainage vessel for the coronary veins and channels the blood back into the right atrium .

Jul 24, 2023 · At a length varying from 3 to 5 cm and a caliber of 1 cm, the coronary sinus is the largest coronary vein. It arises along the posterior aspect of the heart between the left atrium and the left ventricle.

The coronary sinus receives drainage from most epicardial ventricular veins, including the oblique vein of the left atrium (and other left and right atrial veins), the great cardiac vein, the posterior vein of the left ventricle, the left marginal vein, and the posterior interventricular vein.

The coronary sinus (CS) is a significant component of the heart’s circulatory system. It is the largest vein of the heart, responsible for draining over half of the deoxygenated blood from the heart muscle into the right atrium.
