  1. 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. The coronary arteries wrap around the entire heart. The two main branches are the left coronary artery and right coronary artery. The arteries can additionally be categorized based on the area of the heart for which they provide ...

    Distribución de predominio derecho

    La arteria coronaria derecha cruza horizontalmente el surco auriculoventricular y se distribuye en la mayor parte de la cara posterior del ventrículo izquierdo. En el surco emite una rama interventricular posterior (descendente y de menor calibre que el de la arteria que cruza el surco). La rama circunfleja desciende por la cara lateral del ventrículo izquierdo. Toda o casi toda la cara posterior del ventrículo izquierdo queda irrigada por la coronaria derecha. Es el tipo más frecuente: alred...

    Distribución de predominio intermedio

    La arteria coronaria derecha desciende por el surco interventricular (posterior), una rama corta cruza al ventrículo izquierdo. A lo largo del surco, la arteria emite ramas finas a las partes yuxtaseptales de ambos ventrículos. La rama circunfleja cruza la cara lateral del ventrículo izquierdo y se distribuye en la mayor parte de la cara posterior del ventrículo izquierdo. La mayor parte de la cara posterior del ventrículo izquierdo queda irrigada por la rama circunfleja; sólo su porción yuxt...

    Distribución de predominio izquierdo

    Cuando la arteria coronaria izquierda irriga en mayor proporción a los ventrículos y es así como se logra una irrigacion miocardica eficiente y anatómicamente funcional.

    Existen diferentes tipos de patologías coronarias aunque, sin duda, lo más frecuente y de mayor relevancia clínica, debido a prevalencia mundial, es la aterosclerosis coronaria que da lugar a la cardiopatía isquémica. La cardiopatía isquémica es una de las principales causas de mortalidad a nivel mundial y más del 90% de los casos son secundarios a...

  2. The coronary arteries are the arterial blood vessels of coronary circulation. It moves oxygenated blood to the heart muscle. The heart needs constant supply of oxygen to work and survive, much like any other tissue or organ of the body. The coronary arteries wrap around the entire heart.

  3. Coronary artery disease (CAD), also called coronary heart disease (CHD), ischemic heart disease (IHD), myocardial ischemia, or simply heart disease, involves the reduction of blood flow to the heart muscle due to build-up of atherosclerotic plaque in the arteries of the heart. It is the most common of the cardiovascular diseases.

    Coronary circulation is the circulation of blood in the blood vessels that supply the heart muscle. Coronary arteries supply oxygenated blood to the heart muscle. Cardiac veins then drain away the blood after it has been deoxygenated. Because the rest of the body, and most especially the brain, needs a steady supply of oxygenated blood that is free...

    Coronary arteries supply blood to the myocardium and other components of the heart. Two coronary arteries originate from the left side of the heart at the beginning left ventricle. There are three aortic sinuses in the wall of the aorta just superior to the aortic semilunar valve. Two of these, the left posterior aortic sinus and anterior aortic si...

    The papillary muscles attach the mitral valve and the tricuspid valve to the wall of the heart. If the papillary muscles are not functioning properly, the mitral valve may leak during contraction of the left ventricle. This causes some of the blood to travel "in reverse", from th

    During contraction of the ventricular myocardium, the subendocardial coronary vessels are compressed due to the high ventricular pressures. This compression results in momentary retrograde blood flow which further inhibits perfusion of myocardium during systole. However, the epic

    The heart regulates the amount of vasodilation or vasoconstriction of the coronary arteries based upon the oxygen requirements of the heart. This contributes to the filling difficulties of the coronary arteries. Compression remains the same. Failure of oxygen delivery caused by a

    The following are the named branches of the coronary circulation in a right-dominant heart: 1. Aorta Left coronary artery / Left main coronary artery Left circumflex artery Obtuse marginal artery #1 Obtuse marginal artery #2 Left anterior descending artery Diagonal artery #1 Diagonal artery #2 Right coronary artery Atrioventricular nodal branch Rig...

    The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins. These include the great cardiac vein, the middle cardiac vein, the small cardiac vein, the smallest cardiac veins, and the anterior cardiac veins. Cardiac veins carry blood with a poo

    The vessels that deliver oxygen-rich blood to the myocardium are the coronary arteries. When the arteries are healthy, they are capable of autoregulating themselves to maintain the coronary blood flow at levels appropriate to the needs of the heart muscle. These relatively narrow

  4. 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. It travels down the right coronary sulcus, towards the crux of the heart. It supplies the right side of the heart, and the interventricular septum. Contents 1 Structure

  5. The left coronary artery (abbreviated LCA) is a coronary artery that arises from the aorta above the left cusp of the aortic valve, and feeds blood to the left side of the heart muscle. It is also known as the left main coronary artery (abbreviated LMCA) and the left main stem coronary artery (abbreviated LMS ). Contents 1 Branching
