• great vessels
  • Transposition of the great vessels (TGV) is a group of congenital heart defects involving an abnormal spatial arrangement of any of the great vessels: superior and/or inferior venae cavae, pulmonary artery, pulmonary veins, and aorta. (wikipedia.org)
  • On chest X-ray, transposition of the great vessels typically shows a cardio-mediastinal silhouette appearing as an "egg on a string", wherein in which the enlarged heart represents an egg on its side and the narrowed, atrophic thymus of the superior mediastinum represents the string. (wikipedia.org)
  • Cardiac surgery, or cardiovascular surgery, is surgery on the heart or great vessels performed by cardiac surgeons. (wikipedia.org)
  • foramen ovale
  • In the fetus, there is an opening between the right and left atrium (the foramen ovale), and most of the blood flows through this hole directly into the left atrium from the right atrium, thus bypassing pulmonary circulation. (wikipedia.org)
  • As result of these changes, the blood pressure in the left atrium exceeds the pressure in the right atrium, and this pressure difference forces the foramen ovale to close separating the left and right sides of the heart. (wikipedia.org)
  • bypass
  • Therefore, during open heart surgery, the heart is temporarily stopped, and the patient is placed on cardiopulmonary bypass, meaning a machine pumps their blood and oxygen. (wikipedia.org)
  • Cardiopulmonary bypass was developed after surgeons realized the limitations of hypothermia in cardiac surgery: Complex intracardiac repairs take time, and the patient needs blood flow to the body (particularly to the brain), as well as heart and lung function. (wikipedia.org)
  • Cardiac
  • Microablation of the cardiac neural crest in developing chick embryos and genetic anomalies affecting this population of cells in rodents results in persistent truncus arteriosus. (wikipedia.org)
  • Numerous perturbations affecting the cardiac neural crest have been associated with persistent truncus arteriosus, some of which include growth factors (fibroblast growth factor 8 and bone morphogenetic protein), transcription factors (T-box, Pax, Nkx2-5, GATA-6, and Forkhead), and gap junction proteins (Connexin). (wikipedia.org)
  • Because cardiac output is related to the quantity of blood delivered to various parts of the body, it is an important indicator of how efficiently the heart can meet the body's demands for perfusion. (wikipedia.org)
  • Cardiac output is a global blood flow parameter of interest in hæmodynamics, the study of the flow of blood. (wikipedia.org)
  • umbilical
  • Cordocentesis - a procedure to sample some of the umbilical cord blood during pregnancy. (nyhq.org)
  • The term usually encompasses the entire fetoplacental circulation, which includes the umbilical cord and the blood vessels within the placenta that carry fetal blood. (wikipedia.org)
  • The blood flow through the umbilical cord is approximately 35 mL/min at 20 weeks, and 240 mL/min at 40 weeks of gestation. (wikipedia.org)
  • persists
  • The dorsal end of the second gives origin to the stapedial artery, a vessel which typically atrophies in humans but persists in some mammals. (wikipedia.org)
  • left
  • Aorta: the blood vessel through which oxygenated blood from the left ventricle enters the systemic circulation. (wikipedia.org)
  • The oxygen-rich ("red") blood then returns to the left heart, via the pulmonary veins, and is pumped through the aorta to the rest of the body, including the heart muscle itself. (wikipedia.org)
  • The continuation of this blood flow is into the left ventricle, and from there it is pumped through the aorta into the body. (wikipedia.org)
  • In a baby with hypoplastic left heart syndrome, if the natural connections between the heart's left and right sides (foramen oval and ductus arteriosus) are allowed to close, he or she may go into shock. (wikipedia.org)
  • Oxygen-rich blood returns to the left atrium, where it then travels into the left ventricle. (wikipedia.org)
  • The left ventricle pushes the oxygenated blood into the aorta to be circulated to the rest of the body. (wikipedia.org)
  • The surgeries rearrange the blood flow within the heart and allow the left ventricles to do the work for the underdeveloped right side of the heart. (wikipedia.org)
  • atrial
  • Atrial septostomy allows more of the oxygen-rich blood to circulate throughout the body. (wikipedia.org)
  • Atrial septostomy relieves some of this pressure, but at the cost of lower oxygen levels in the blood (hypoxia). (wikipedia.org)
  • carries
  • Hemoglobin - a type of protein in the red blood cells that carries oxygen to the tissues of the body. (nyhq.org)
  • newborn
  • In full-term or preterm infants, hemolytic disease of the newborn (incompatibility between the blood types of the mother and baby) can lead to anemia. (kidshealth.org)
  • abnormally
  • In acidosis, the pH of the blood is abnormally low. (blogspot.com)
  • For example, in the disorder hypertension, the prefix "hyper-" means "high" or "over", and the root word "tension" refers to pressure, so the word "hypertension" refers to abnormally high blood pressure. (wikipedia.org)
  • systemic
  • The systemic and the pulmonary circulation are connected. (wikipedia.org)
  • The aorta distributes oxygenated blood to all parts of the body through the systemic circulation. (wikipedia.org)
  • This is the systemic circulation part of blood flow, the other loop of an interconnected normal cardio-pulmonary system. (wikipedia.org)
  • He was the first known physician to describe completely and in detail the systemic circulation and properties of blood being pumped to the brain and body by the heart, though earlier writers, such as Realdo Colombo, Michael Servetus, and Jacques Dubois, had provided precursors of the theory. (wikipedia.org)
  • inferior
  • In about four people out of five, there is a connecting branch between the inferior laryngeal nerve, a branch of the RLN, and the internal laryngeal nerve, a branch of the superior laryngeal nerve. (wikipedia.org)
  • arterial
  • 1st Update: She's intibated, all the lines are in (Central and Arterial Line which will be used to check her blood pressure constantly), they are draping her and getting her already to make the incision and will be looking at the aorta shortly. (blogspot.com)
  • flows
  • Blood flows from the upper curvature to the upper regions of the body, located above the heart - namely the arms, neck, and head. (wikipedia.org)
  • normal
  • Treatment is with neonatal surgical repair, with the objective of restoring a normal pattern of blood flow. (wikipedia.org)
