Where is the anterior interventricular artery?

Where is the anterior interventricular artery?

The anterior interventricular artery, often clinically termed the left anterior descending artery, is a branch of the left coronary artery. It originates at the left margin of the pulmonary trunk, anterior to the left atrial auricle.

Where are the coronary arteries and veins located?

The heart receives its own supply of blood from the coronary arteries. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood.

Where do Thebesian veins drain into?

The anterior cardiac veins drain directly into the right atrium. There are also tiny veins in the walls of each of the chambers called the thebesian veins or venate cordis minimi, which drain directly into their own relevant chamber.

Where is the posterior cardiac vein?

The middle cardiac vein, also known as the posterior interventricular vein, is a vessel located on the posterior aspect of the heart. It arises at the cardiac apex and runs within the posterior interventricular groove. It ends by draining into the right atrium via the coronary sinus.

Which vessel is situated on the anterior interventricular groove?

The anterior interventricular sulcus is situated on the sternocostal surface of the heart, close to its left margin. The anterior interventricular branch of the left coronary artery runs in the sulcus along with the great cardiac vein….

Where is the ostial LAD located?

It’s called the LAD because is on the left side of the heart (left) it runs down the front wall of the heart (anterior descending). The Left anterior descending artery typically supplies over half of the heart muscle with blood, so twice as much as the other coronary arteries.

What is Venae Cordis Minimae?

The venae cordis minimae (singular: vena cordis minima), meaning “smallest cardiac veins”, also known as Thebesian veins (variably capitalized in the literature) are a small group of valveless myocardial coronary veins within the walls of each of the four cardiac chambers that drain venous blood directly into each of …

Where does venae cordis minimae flow?

What is the largest vein that drains the heart?

The coronary sinus is the largest cardiac vein in terms of diameter. Various landmarks have been described as the location of the coronary sinus origin, including where the oblique vein of the left atrium meets the great cardiac vein and at the valve of Vieussens [4,7].

What are the 3 main cardiac veins?

great cardiac vein.

Where is the interventricular groove located?

the heart
The interventricular groove runs anteriorly toward the apex and contains the great cardiac vein. Posteriorly, it continues along the inferior surface of the heart toward the right margin and contains the middle cardiac vein. The heart has five surfaces, anterior, posterior, inferior, and a right and left.
