  • Coarctation of the aorta (CoA or CoAo), also called aortic narrowing, is a congenital condition whereby the aorta is narrow, usually in the area where the ductus arteriosus (ligamentum arteriosum after regression) inserts. (wikipedia.org)
  • Some children born with coarctation of the aorta have other heart defects too, such as aortic stenosis, ventricular septal defect, patent ductus arteriosus or mitral valve abnormalities. (wikipedia.org)
  • aortic
  • Postductal coarctation is most likely the result of the extension of a muscular artery (ductus arteriosus) into an elastic artery (aorta) during fetal life, where the contraction and fibrosis of the ductus arteriosus upon birth subsequently narrows the aortic lumen. (wikipedia.org)
  • An aortic aneurysm is a bulging, weakened area in the wall of the aorta. (rochester.edu)
  • Aneurysms occur most often in the portion of the aorta that runs through the abdomen (abdominal aortic aneurysm). (rochester.edu)
  • An abdominal aortic aneurysm is also called AAA or triple A. A thoracic aortic aneurysm refers to the part of the aorta that runs through the chest. (rochester.edu)
  • blood
  • Since the aorta is narrowed, the left ventricle must generate a much higher pressure than normal in order to force enough blood through the aorta to deliver blood to the lower part of the body. (wikipedia.org)
  • Preductal coarctation results when an intracardiac anomaly during fetal life decreases blood flow through the left side of the heart, leading to hypoplastic development of the aorta. (wikipedia.org)
  • In more severe cases, where severe coarctations, babies may develop serious problems soon after birth because not enough blood can get through the aorta to the rest of their body. (wikipedia.org)
  • The aorta is the largest blood vessel in the body. (rochester.edu)
