  • left main c
  • It is also contraindicated in people without demonstrated significant vascular obstruction, as well as in those with severe multivessel disease or more than 50% stenosis of the left main coronary artery. (thefreedictionary.com)
  • stents
  • Current implementations for Cardiology uses are sometimes limited by lengthy protocols, claustrophobia and contraindications based on some complex metallic implants (pacemakers, defibrillators, insulin pumps), while artificial valves and coronary stents are generally not problematic. (wikipedia.org)
  • Selective
  • Selective coronary arteriography. (springer.com)
  • These findings are in excellent agreement with the conventional selective coronary angiogram performed a few hours later in the hospital cardiology unit ( Figure 9b ). (esrf.eu)
  • intravenous
  • Rubenstein and his colleagues E. Barrie Hughes and Robert Hofstadter posited that there may be numerous applications of this intensely powerful, tuneable, and linearly polarized radiation to biomedical imaging, including intravenous coronary arteriography. (wikipedia.org)
  • contrast
  • The programme addresses the fundamental concerns associated with conventional angiography, which requires the injection of a contrast agent directly into the coronary arteries by means of arterial catheterisation. (esrf.eu)
  • The X-ray energies and intensity are those required for the dual-energy digital subtraction technique to enhance the image contrast of the coronary arteries following venous injection of the iodinated contrast agent. (esrf.eu)
  • To make it possible to do angiography and surgery on the same day and largely diminish the possibility of renal failure, Mayo physicians use other contrast agents. (eurekalert.org)
  • Visipaque is commonly used as a contrast agent during coronary angiography. (wikipedia.org)
  • CT angiography is a contrast CT where images taken with a certain delay after injection of radiocontrast to result in a high radiodensity within the blood vessels of interest. (wikipedia.org)
  • A typical coronary CT calcium scan is done without the use of radiocontrast, but it can possibly be done from contrast-enhanced images as well, such as in coronary CT angiography. (wikipedia.org)
  • atherosclerosis
  • On the other hand, the 6A allele has been found to be associated with diseases characterized by insufficient MMP-3 expression due to a lower promoter activity of the 6A allele, such as progressive coronary atherosclerosis. (wikipedia.org)
  • radiation exposure
  • Harms of overuse of CT angiography include radiation exposure and the possibility of finding then seeking treatment for a clinically insignificant pulmonary embolism which ought not be treated. (wikipedia.org)
  • Patient
  • When the patient experienced no ill effects from the dye and the X-ray films were so much better than previous angiography, a new standard was established. (encyclopedia.com)
  • Further treatment tactics for the patient are determined on the basis of expert analysis of the data provided by the coronary angiography. (emcmos.ru)
