Question: Where does anterior cardiac veins drain?

The anterior cardiac veins are a group of parallel coronary veins that course over the anterior surface of the right ventricle, draining it and entering directly into the right atrium. They may occasionally drain into the small cardiac vein.

Where do the cardiac veins drain?

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 do coronary veins drain into?

The coronary sinus drains into the right atrium, at the coronary sinus orifice, an opening between the inferior vena cava and the right atrioventricular orifice or tricuspid valve.

What does the anterior cardiac vein do?

The anterior cardiac veins (or anterior veins of right ventricle) comprise a variable number of small vessels, usually between two and five, which collect blood from the front of the right ventricle and open into the right atrium; the right marginal vein frequently opens into the right atrium, and is therefore …

What cardiac vein drains the anterior portion of ventricles?

The anterior wall of the left ventricle and the interventricular septum are drained by branches of the anterior interventricular vein, known as the great cardiac vein on the annulus.

What is the largest vein that drains the heart?

Anterior Interventricular Vein and Great Cardiac Vein

The great cardiac vein, the longest venous vessel of the heart, consists of the anterior interventricular vein and its continuation along the atrioventricular groove [4,7].

What are the 3 cardiac 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).

Is there a coronary vein?

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.

Where does the middle cardiac vein drain blood 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.

How many veins drain directly into the coronary sinus vein?

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.

Is there a vein in your heart?

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.

What is cardiac anatomy?

The cardiovascular system consists of the heart, which is an anatomical pump, with its intricate conduits (arteries, veins, and capillaries) that traverse the whole human body carrying blood.

What may occur if there was a blockage to a coronary artery?

A completely blocked coronary artery will cause a heart attack. The classic signs and symptoms of a heart attack include crushing pressure in your chest and pain in your shoulder or arm, sometimes with shortness of breath and sweating.
