Coronary Sinus Anatomy

The circumference of the vein is larger than average and is big enough to allow blood to be deposited by most veins that enter the heart. In human cardiovascular system.

Coronary Arteries And Cardiac Veins Anatomy And Branches

This transition point is usually marked by the presence of intravenous valves which can obstruct catheter and lead placement.

Coronary sinus anatomy. The coronary sinus empties directly into the right atrium near the conjunction of the posterior interventricular sulcus and the coronary sulcus crux cordis area located between the inferior vena cava and tricuspid valve. The coronary sinus develops from one of the two sinus horns of the sinus venosum. 85 of venous drainage occurs via the coronary sinus which is formed from the cardiac veins.

The great cardiac vein runs with the lad the middle cardiac vein follows the pda. Conventional coronary venous anatomy. 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.

Describe the normal anatomy of the cardiac venous system. The great cardiac vein terminates in the coronary sinus a junction defined by the presence of the left atrial oblique vein. The other horn becomes part of the right atrium.

The right ventricle the right inferior portion of the heart is the chamber from which the pulmonary artery carries blood to the lungs. Normal anatomy and congenital abnormalities abstract. The coronary sinus is a collection of smaller veins that merge together to form the sinus or large vessel which is located along the hearts posterior rear surface between the left ventricle and left atrium.

Another important branch is the middle cardiac vein. The main vein of the greater venous system is the cs that runs in the posterior aspect of the coronary groove. This atrial ostium can be partially covered by a thebesian valve although the anatomy of this valve is highly variable.

Imaging of the coronary venous system has traditionally been. Coronary sinus gross anatomy. Chambers of the heart the body respectively and the coronary sinus draining blood from the heart itself.

The tributaries of the greater and smaller cardiac veins or the thebesian veins. The coronary sinus courses along the posterior wall of the left atrium into the left atrioventricular groove. Blood flows from the right atrium to the right ventricle.

Knowledge of the anatomy of the coronary sinus. Imaging of the coronary sinus. Coronary sinus anatomy the myocardium drains mainly by two groups of veins.

It returns blood from the heart muscle and is protected by a semicircular fold of the lining membrane of the auricle.
