2023年7月13日 · The coronary arteries are responsible for carrying nutrient-rich, oxygenated blood from the left ventricle to the myocardium; while the coronary veins take nutrient – poor deoxygenated blood away from the myocardium and to the right atrium.

2024年11月24日 · The coronary veins return deoxygenated blood from the myocardium back to the right atrium. Most venous blood returns via the coronary sinus. Coronary venous anatomy is highly variable, but is generally comprised of three groups: cardiac veins which drain into the coronary sinus: great cardiac vein. middle cardiac vein / posterior ...

2024年1月8日 · Overview of the branching structure of the coronary arteries. The venous drainage of the heart is mostly through the coronary sinus – a large venous structure located on the posterior aspect of the heart. The cardiac veins drain into the coronary sinus, which in turn, empties into the right atrium.

Coronary Venous Anatomy. Coronary venous flow occurs during diastole and systole, and the coronary venous system drains the myocardium of oxygen-depleted blood. The coronary venous system dominates the arterial system; there are at least twice as many veins as arteries in human myocardial tissue [1, 2].

The major venous vessels of the human heart are: coronary sinus, the anterior interventricular veins, left marginal veins, posterior veins of the left ventricle, and the posterior interventricular veins (see also the Coronary System Tutorial).

2023年7月24日 · Coronary veins are responsible for draining deoxygenated blood from the myocardium into the cardiac chambers. Comprised of two venous systems, coronary veins classify into either the greater cardiac venous system or the smaller cardiac venous system.

2012年11月23日 · Knowledge of the anatomy of the coronary arteries and subjacent cardiac veins as displayed with maximum intensity and volume-rendered projections is important for correct image interpretation of coronary CT angiography examinations.

2023年7月24日 · The coronary venous network drains deoxygenated blood from the myocardium into one of two systems: the greater cardiac venous system and the smaller cardiac venous system. These systems are comprised of many complementary veins, the majority of which coalesce to form the coronary sinus.

Coronary venous anatomy can be divided into the greater cardiac venous system and the lesser cardiac venous system. With protocol optimization, including appropriate contrast bolus timing, coronary veins can be depicted with excellent detail on CT.

2014年7月7日 · ANATOMY OF THE CORONARY VENOUS SYSTEM. The coronary sinus ostium is located in the posteroseptal area of the right atrium and is the final part of the coronary venous system.
