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.
Which veins open into coronary sinus?
The coronary sinus receives blood mainly from the
small, middle, great and oblique cardiac veins
. It also receives blood from the left marginal vein and the left posterior ventricular vein. It drains into the right atrium.
Which veins drain into the coronary sinus?
In summary, the following tributaries drain into the coronary sinus:
Great cardiac vein
.
Oblique vein of the left atrium
.
Posterior vein of the left ventricle
.
Does middle cardiac vein drain into coronary sinus?
The middle cardiac vein
drains into the coronary sinus
or directly into the right atrium [4]. The small cardiac vein, also known as the right cardiac vein [12], commonly drains the inferior and lateral wall of the right ventricle.
Where do coronary veins drain to?
The great cardiac vein, the middle cardiac vein, and the small cardiac vein all drain into
the coronary sinus
(which opens into the right atrium). The anterior cardiac veins drain directly into the right atrium.
Where does small cardiac vein drain?
The small cardiac vein is a vein of the heart which accompanies the acute marginal artery from the RCA. It courses in the right posterior atrioventricular groove and drains into the coronary sinus close to its termination but may drain directly into the right atrium. It drains
the right ventricle
.
What are the major coronary veins?
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).
What are the three major veins that empty into the coronary sinus?
- Great cardiac vein.
- Oblique vein of the left atrium.
- Posterior vein of the left ventricle.
- Middle cardiac vein.
- Small cardiac vein.
How do you access the coronary sinus?
Access to the coronary sinus is best made by
two combination systems with a steerable electrophysiology catheter or a telescoping inner catheter
. Furthermore, special guiding catheters for the access from the right subclavian vein particularly to upgrade right-sided pacemakers and ICD systems have been developed.
Where does the coronary sinus open?
The function of the coronary sinus is to drain the venous blood from the majority of the heart. It opens
into the right atrium between the opening of inferior vena cava, the fossa ovalis and the right atrioventricular orifice
.
Where does the middle cardiac vein drain from?
The middle cardiac vein or posterior interventricular vein is a vein of the heart which accompanies the posterior interventricular artery. It courses in the posterior interventricular groove and drains
directly into the coronary sinus
close to it’s termination.
What does not drain into the coronary sinus?
What cardiac veins do not drain into the coronary sinus?
Anterior cardiac veins and the Thebesian veins
. The anterior cardiac veins open directly into right atrium and receive blood from the surface of right ventricle. What vessels drain the myocardium and open directly into cavities, mostly atria?
Which artery of heart is responsible for cardiac dominance?
The artery that supplies the posterior third of the interventricular septum –
the posterior descending artery (PDA)
determines the coronary dominance. If the posterior descending artery is supplied by the right coronary artery (RCA), then the coronary circulation can be classified as “right-dominant.”
Is there a coronary vein?
Coronary veins can be organized into two groups:
the greater and smaller cardiac venous system
. Also known as the obtuse marginal vein, the left marginal vein drains the myocardium of the left ventricle. [2] This vein travels along the left oblique marginal surface of the heart.
What is the main function of the coronary veins?
Coronary arteries
supply blood to the heart muscle
. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away. The coronary arteries wrap around the outside of the heart.
Where do Thebesian veins drain?
Smallest cardiac veins (Thebesian veins) The smallest cardiac veins, also known as the Thebesian veins, are small vessels of the heart that drain
the inner surface of the myocardium
.
