Where is the coronary sinus vein located?

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.

Where is the coronary sinus located in the heart?

Coronary Sinus | Atlas of Human Cardiac Anatomy. Location: The coronary sinus is located in the posterior portion of the coronary sulcus on the diaphragmatic or posterior surface of the heart.

Where does blood go from coronary sinus?

The function of the coronary sinus is to receive deoxygenated blood from the epicardial ventricular veins, which are the veins of the heart muscle. The coronary sinus delivers this blood to the right atrium before it eventually travels back to the lungs to be oxygenated again.

Where is the left vena cava?

Background. Persistent left superior vena cava (PLSVC) is a rare vascular anomaly that begins at the junction of the left subclavian and internal jugular veins, passes through the left side of the mediastinum adjacent to the arcus aorta. It mostly drains into the right atrium via the coronary sinus (CS).

How do you know you have coronary sinus?

The coronary sinus starts at the junction of the great cardiac vein and the oblique vein of the left atrium. The end of the great cardiac vein and the coronary sinus is marked by the Vieussens valve. The coronary sinus runs transversely in the left atrioventricular groove on the posterior side of the heart.

Which vein continues as the coronary sinus?

great cardiac vein
The great cardiac vein commonly continues until it merges with the coronary sinus [7]. The lateral veins, also known as the left marginal veins or the obtuse marginal veins, course along the left side of the heart and drain the left ventricular myocardium into the great cardiac vein or coronary sinus [7].

Which coronary artery is the Widowmaker?

The widow-maker is a massive heart attack that occurs when the left anterior descending artery (LAD) is totally or almost completely blocked. The critical blockage in the artery stops, usually a blood clot, stops all the blood flow to the left side of the heart, causing the heart to stop beating normally.

Can you live without a vena cava?

Absence of the inferior vena cava is a rare vascular anomaly, which usually remains asymptomatic in childhood. It is recognized as the risk factor for deep venous thrombosis, since the collateral circulation does not provide adequate drainage of the lower limbs.

Where does left SVC drain?

Typically, the left superior vena cava drains to the right atrium via the coronary sinus, but occasionally it drains directly into the left atrium. Duplication of the superior vena cava is more common and is even more often associated with congenital heart disease.

Do all cardiac veins drain into the coronary sinus?

The coronary sinus is a collection of veins joined together to form a large vessel that collects blood from the heart muscle (myocardium). It delivers less-oxygenated blood to the right atrium, as do the superior and inferior venae cavae….

What is a sinus in the heart?

The sinus node is an area of specialized cells in the upper right chamber of the heart. This area controls your heartbeat. Normally, the sinus node creates a steady pace of electrical impulses.
