Dextrocardia (from Latin dextro 'right hand side' and Greek kardia 'heart') is a rare congenital condition in which the apex of the heart is located on the right side of the body, rather than the more typical placement towards the left. [1]
The right coronary artery supplies oxygenated blood to the right atrium, the right ventricle, and the posterior third and inferior end of the interventricular septum. [2] [5] It may also supply 25% to 35% of the left ventricle (LV). [10] There is significant overlap of supply of the coronary arteries. [2]
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
The moderator band is important because it carries part of the right bundle branch of the atrioventricular bundle of the conduction system of the heart to the anterior papillary muscle. [1] This shortcut across the chamber of the ventricle ensures equal conduction time in the left and right ventricles, allowing for coordinated contraction of ...
The largest part of the heart is usually slightly offset to the left side of the chest . In a rare congenital disorder (dextrocardia) the heart is offset to the right side and is felt to be on the left because the left heart is stronger and larger, since it pumps to all body parts.
The right marginal arteries perfuse the right ventricle and the posterior descending artery perfuses the left ventricular posterior and inferior walls. There is also the conus artery , which is only present in about 45 percent of the human population, and which provides collateral blood flow to the heart when the left anterior descending artery ...
The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...
A left-to-right shunt is when blood from the left side of the heart goes to the right side of the heart. This can occur either through a hole in the ventricular or atrial septum that divides the left and the right heart or through a hole in the walls of the arteries leaving the heart, called great vessels.
