In the blood supply of the heart, the right coronary artery (RCA) is an artery originating above the right cusp of the aortic valve, at the right aortic sinus in the heart. [1] [2] It travels down the right coronary sulcus, towards the crux of the heart.
The coronary arteries are the arterial blood vessels of coronary circulation, which transport oxygenated blood to the heart muscle. The heart requires a continuous supply of oxygen to function and survive, much like any other tissue or organ of the body. [1] The coronary arteries wrap around the entire heart.
Transposed vessels can present with atriovenous, ventriculoarterial and/or arteriovenous discordance. The effects may range from a slight change in blood pressure to an interruption in circulation depending on the nature and degree of the misplacement, and on which specific vessels are involved.

In anatomy, the venae cavae (/ ˈ v iː n i ˈ k eɪ v i /; [1] sg.: vena cava / ˈ v iː n ə ˈ k eɪ v ə /; from Latin 'hollow veins') [2] are two large veins (great vessels) that return deoxygenated blood from the body into the heart. In humans they are the superior vena cava and the inferior vena cava, and both empty into the right atrium ...
Posterior wall of the pericardial sac, showing the lines of reflection of the serous pericardium on the great vessels. (Transverse sinus labeled at center. (Transverse sinus labeled at center. Oblique sinus not labeled, but visible inferior to transverse sinus between the right and left pulmonary veins )
For all structures except the heart, the images are usually taken using a technique called digital subtraction angiography or DSA. Images in this case are usually taken at 2–3 frames per second, which allows the interventional radiologist to evaluate the flow of the blood through a vessel or vessels. This technique "subtracts" the bones and ...
Angiogenesis is the physiological process through which new blood vessels form from pre-existing vessels, [1] [2] [3] formed in the earlier stage of vasculogenesis. Angiogenesis continues the growth of the vasculature mainly by processes of sprouting and splitting, but processes such as coalescent angiogenesis , [ 4 ] vessel elongation and ...
The procedure was developed to treat transposition of the great vessels, eponymously known as blue baby syndrome. This is a condition in which the aorta and pulmonary artery are attached to the heart in an opposite order from what is usually present at birth, resulting in the aorta being the outflow tract for the right ventricle and the ...
