  • While "on-line" quantitative angiographic is somewhat cumbersome to use in the catheterization laboratory, "off-line" quantitative angiography has proven invaluable for research investigation in determining the effect of new drugs and devices on lumen dimensions early and late after percutaneous coronary interventions. (wikidoc.org)
  • Modern cardiology has seen enormous technological advances over the past few years, so much so that many of the more complicated procedures involving the coronary arteries can now be performed via access sites in the lower arm (radial access). (immanuel.de)

  • Your exam will measure the amount of calcium deposits surrounding your coronary arteries and assess the lumen of the coronary arteries for any narrowing. (ssdev.ca)
  • A CAG consists of videos acquired separately for the left coronary artery and the right coronary artery (LCA and RCA, respectively). (ku.dk)
  • The right coronary artery (RCA) supplies the posterior wall of the heart and originates in a separate section of the aorta. (immanuel.de)
  • With angiography test, a cardiologist can detect narrowed arteries and suggest necessary treatments as indicated. (ariamedtour.com)
  • Using a combination of X-rays and computer technology to produce comprehensive, detailed images, Coronary CTA can detect both calcified or hard plaques and noncalcified or soft plaques. (ssdev.ca)
  • Cardiac catheterisation and coronary angiography can provide important information about the heart and the blood vessels that surround and supply it. (nhsinform.scot)
  • Angiography is an effective test to diagnose conditions relating to heart and blood vessels. (ariamedtour.com)
  • Cerebral angiography is carried out to provide an image of the brain's blood vessels. (ariamedtour.com)
  • It will also assess the wall of the coronary vessels for any soft plaques. (ssdev.ca)

  • The catheter is then threaded through the major blood vessels and into the chambers of the heart and/or into the coronary arteries. (msdmanuals.com)
  • Usually an angiography by traditional method will be repeated if CT angio shows significant problem needing intervention. (ndtv.com)
  • The emerging field of coronary physiology allows operators to perform quantitative measurements of lesion severity and are evidence based to guide the need for coronary intervention. (rcpe.ac.uk)
