Coronary Sinus Anatomy

Chambers of the heart the body respectively and the coronary sinus draining blood from the heart itself. In human cardiovascular system.

Coronary Sinus And Ventricular Veins It Is Essential To

This atrial ostium can be partially covered by a thebesian valve although the anatomy of this valve is highly variable.

Coronary sinus anatomy. Knowledge of the anatomy of the coronary sinus. The coronary sinus courses along the posterior wall of the left atrium into the left atrioventricular groove. The main vein of the greater venous system is the cs that runs in the posterior aspect of the coronary groove.

Imaging of the coronary sinus. The great cardiac vein terminates in the coronary sinus a junction defined by the presence of the left atrial oblique vein. 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.

Conventional coronary venous anatomy. 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.

It returns blood from the heart muscle and is protected by a semicircular fold of the lining membrane of the auricle. 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. Another important branch is the middle cardiac vein.

The tributaries of the greater and smaller cardiac veins or the thebesian veins. This transition point is usually marked by the presence of intravenous valves which can obstruct catheter and lead placement. Normal anatomy and congenital abnormalities abstract.

Blood flows from the right atrium to the right ventricle. 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. Coronary sinus gross anatomy.

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. The coronary sinus develops from one of the two sinus horns of the sinus venosum. Describe the normal anatomy of the cardiac venous system.

Coronary sinus anatomy the myocardium drains mainly by two groups of veins. 85 of venous drainage occurs via the coronary sinus which is formed from the cardiac veins. Imaging of the coronary venous system has traditionally been.

The great cardiac vein runs with the lad the middle cardiac vein follows the pda.
