What drains into the coronary artery?

Capillary blood flow enters venules that join together to form cardiac veins that drain into the coronary sinus located on the posterior side of the heart, which drains into the right atrium….Coronary Anatomy and Blood Flow.

Anatomic Region of Heart	Coronary Artery (most likely associated)
Posterior	Right coronary artery

Which veins drain into coronary sinus?

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.

What happens when the right coronary artery is blocked?

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.

How do you access the coronary sinus?

Access to the coronary sinus is best made by two combination systems with a steerable electrophysiology catheter or a telescoping inner catheter. Furthermore, special guiding catheters for the access from the right subclavian vein particularly to upgrade right-sided pacemakers and ICD systems have been developed.

Where does each coronary artery supply?

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.

Which coronary artery supplies the apex of the heart?

left anterior descending artery
The left anterior descending artery (LAD) is the largest coronary artery runs anterior to the interventricular septum in the anterior interventricular groove, extending from the base of the heart to the apex.

What does coronary sinus drain?

The coronary sinus is the major venous tributary of the greater cardiac venous system; it is responsible for draining most of the deoxygenated blood leaving the myocardium.

What is coronary sinus in heart?

The coronary sinus is a collection of smaller veins that merge together to form the sinus (or large vessel), which is located along the heart’s posterior (rear) surface between the left ventricle and left atrium.

What causes dilated coronary sinus?

A dilated CS can result from increased blood flow due to abnormal venous drainage in the left superior vena cava, total anomalous intra-cardiac pulmonary venous drainage, severe tricuspid regurgitation, CS diverticulum, or a coronary artery to CS fistula.

What is coronary sinus rhythm?

A superior and leftward P axis, the so-called coronary sinus rhythm, has been reported in various congenital cardiac lesions. It has most commonly been reported in association with sinus venosus atrial septal defects.
