  • A 30 year old male with native coarctation of the aorta was referred for breathlessness and uncontrolled hypertension. (scmr.org)
  • Coarctation of the aorta is a relatively common defect that occurs in approximately 6-8 % of patients with congenital heart disease and is commonly associated with a bicuspid aortic valve. (scmr.org)
  • Intravascular stents are finding increased applications in the treatment of patients with native coarctation of the aorta and percutaneous intervention is a reasonable alternative to surgical correction. (scmr.org)
  • Late magnetic resonance surveillance of repaired coarctation of the aorta. (scmr.org)
  • 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)
  • left
  • 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)
  • adherent
  • In a double immunofluorescence experiment, the adherent monolayer culture of rat thoracic aorta cells illustrated above was fixed, permeabilized, blocked with 10 percent normal goat serum, and treated with a cocktail of mouse anti-histones (pan) and rabbit anti-PMP 70 (peroxisomal membrane protein) primary antibodies, followed by goat anti-mouse and anti-rabbit secondary antibodies (IgG) conjugated to Texas Red and Alexa Fluor 488, respectively. (fsu.edu)
  • The technique of double immunofluorescence was employed to simultaneously label an adherent culture of rat thoracic aorta (A-10 line) cells (illustrated above) with mouse anti-histone and rabbit anti- beta -catenin primary antibodies, followed by goat anti-mouse and anti-rabbit secondary antibodies conjugated to Marina Blue (histones) and Rhodamine Red-X ( beta -catenin), respectively. (fsu.edu)
  • The adherent culture of rat thoracic aorta cells featured in the digital image above was stained with Alexa Fluor 488 conjugated to the lectin concanavalin A. Alexa Fluor 568 conjugated to phalloidin and DAPI were also used to label the culture, targeting filamentous actin and nuclear DNA, respectively. (fsu.edu)
  • chest
  • Injury of the thoracic aorta refers to any injury which affects the portion of the aorta which lies within the chest cavity. (wikipedia.org)
  • The use of chest tubes in postoperative thoracic care was reported in 1922, and they were regularly used post-thoracotomy in World War II, though they were not routinely used for emergency tube thoracostomy following acute trauma until the Korean War. (wikipedia.org)
  • inferior
  • Throughout human evolution, the first thoracic and inferior cervical ganglia merged - and this resulting ganglion is called the stellate ganglion (so called because of its radiating pattern similar in appearance to a star). (wikipedia.org)
  • compliance
  • Theoretically, the systemic pulse pressure can be conceptualized as being proportional to stroke volume, or the amount of blood ejected from the left ventricle during systole and inversely proportional to the compliance of the aorta. (wikipedia.org)
  • deceleration
  • It may be due to different rates of deceleration of the heart and the aorta, which is in a fixed position. (wikipedia.org)
  • The tethering of the aorta by the ligamentum arteriosum makes the site prone to shearing forces during sudden deceleration. (wikipedia.org)
  • cells
  • View a smaller image of the rat thoracic aorta (A-10) cells. (fsu.edu)
  • The rat thoracic aorta cells presented in the digital image above were immunofluorescently labeled with mouse anti- alpha -tubulin primary antibodies followed by goat anti-mouse secondary antibodies conjugated to Alexa Fluor 568. (fsu.edu)
  • The culture of rat thoracic aorta cells illustrated above was fixed, permeabilized, and blocked with 10-percent normal goat serum in phosphate-buffered saline prior to immunofluorescent labeling with rabbit primary antibodies to giantin, a protein resident in the Golgi complex of mammalian cells. (fsu.edu)
  • Found primarily lining the hollow organs of the body, such as the thoracic aorta from which A-10 cells were derived, smooth muscle cells are usually arranged in dense sheets. (fsu.edu)
  • tear
  • For all intents and purposes, the latter is used when a tear occurs across all or nearly all of the circumference of the aorta. (wikipedia.org)
  • Since the aorta branches directly from the heart to supply blood to the rest of the body, the pressure within it is very great, and blood may be pumped out of a tear in the blood vessel very rapidly. (wikipedia.org)
  • Since high blood pressure could exacerbate an incomplete tear in the aorta or even separate it completely from the heart, which would almost inevitably kill the patient, hospital staff take measures to keep the blood pressure low. (wikipedia.org)
  • Mechanism
  • A more recently proposed mechanism is that the aorta can be compressed between bony structures (such as the manubrium, clavicle, and first rib) and the spine. (wikipedia.org)
  • In the ascending aorta (the portion of the aorta which is almost vertical), one mechanism of injury is torsion (a two-way twisting). (wikipedia.org)
  • atherosclerosis
  • 4-6 Fatty 'dots' and streaks, which may represent the early stages of atherosclerosis, have been found in the aortas of babies and infants. (scielo.org.za)
  • If the aorta becomes rigid in conditions such as arteriosclerosis or atherosclerosis, the pulse pressure would be very high. (wikipedia.org)
  • relaxation
  • Arginine restores cholinergic relaxation of hypercholesterolemic rabbit thoracic aorta. (ahajournals.org)
  • CONCLUSIONS We conclude that the endothelium-dependent relaxation is normalized in hypercholesterolemic rabbit thoracic aorta by in vivo exposure to L-arginine, the precursor for EDRF. (ahajournals.org)
  • The NO-cGMP pathway may be involved in the relaxation of DL0805 in endothelium-intact aorta. (mdpi.com)
  • usually
  • There are usually 22-23 pairs of these ganglia: 3 in the cervical region (cervical ganglia), 11 in the thoracic region (note the presence of the stellate cervicothoracic ganglia), 4 in the lumbar region and 4-5 in the sacral region. (wikipedia.org)
  • type
  • Fellows are trained to manage all type of thoracic surgeries which include video-assisted thoracoscopic surgery (VATS), open thoracotomy, and advanced airway procedures involving the trachea. (wikipedia.org)
  • Effect
  • The beneficial effect of hypothermia on ischaemic intact kidneys was demonstrated by Owens in 1955 when he showed that, if dogs were cooled to 23-26 °C, and their thoracic aortas were occluded for 2 hours, their kidneys showed no apparent damage when the dogs were rewarmed. (wikipedia.org)
  • repair
  • However, morbidity and mortality rates for surgical repair of the aorta for this condition are among the highest of any cardiovascular surgery. (wikipedia.org)

  • lung
  • Lung CT is now considered as the gold standard not only for the diagnosis of pneumothorax, pleural effusion, lung consolidation, atelectasis and alveolar-interstitial syndrome but also for guiding therapeutic procedures in critically ill patients, such as trans-thoracic drainage of localized pneumo-thorax, empyema or lung abscess. (biomedcentral.com)
  • A thoracotomy is a major surgical procedure-it is the first step in many thoracic surgeries including lobectomy or pneumonectomy for lung cancer-and as such requires general anesthesia with endotracheal tube insertion and mechanical ventilation. (wikipedia.org)
