  • angiography
  • Adults with SCAD will be identified both retrospectively and prospectively.Confirmation of the diagnosis by review of coronary angiography will be required before proceeding with the informed consent process and blood or saliva sample procurement. (clinicaltrials.gov)
  • Stenosis
  • A significant stenosis in the proximal first obtuse marginal branch of the left circumflex coronary artery was also noted. (massgeneral.org)
  • Curved multiplanar reconstruction of a patent left circumflex coronary artery (white arrows) demonstrates a proximal stenosis/occlusion at the origin of the first obtuse marginal branch (black arrows). (massgeneral.org)
  • Single view from the patient's catheter coronary angiogram demonstrates similar findings, with long segment occlusion of the LAD (white arrows), large tortuous first diagonal branch collaterals (dotted arrow), and high grade stenosis in the proximal first obtuse marginal branch (black arrow). (massgeneral.org)
  • intervention
  • The major component of HDL consists of apolipoprotein A-I (ApoA I). Recent intervention studies with synthetic HDL particles and recombinant ApoA-I have shown that HDL has the capacity to reverse coronary atherosclerosis. (bioportfolio.com)
  • epicardial
  • 13 In this study, we describe abnormalities in the formation of the coronary vasculature in Lp , resulting from non-cell-autonomous effects on migration and/or differentiation of transformed epicardial cells. (ahajournals.org)
  • blood vessel
  • Some mutations may be inherited (passed on) from a parent without an apparent blood vessel problem while others may develop for the first time in the affected person. (clinicaltrials.gov)
  • Arrhythmias
  • 7-9 Since data acquired over several heartbeats are necessary to acquire a complete data set, coronary CTA is not reliably possible in patients with arrhythmias (scanner design concepts with ≥256 slices may help overcome this limitation). (appliedradiology.com)
  • indications
  • In a consensus document, a group of experts from various professional societies have listed "appropriate" clinical indications for coronary CTA, based mostly on the considerations outlined above (Table 2). (appliedradiology.com)
  • In the following section, potential clinical indications for the use of coronary CTA are outlined as a "Top Ten" list, from the clearest to the least robust and frequent indications. (appliedradiology.com)
  • demonstrates
  • The available literature convincingly demonstrates that coronary CTA, if expertly performed, has a high negative predictive value and thus allows one to rather reliably rule out the presence of CAS. (appliedradiology.com)
  • Curved multiplanar reconstruction of the left anterior descending (LAD) coronary artery demonstrates an occluded segment in the mid LAD segment (arrows). (massgeneral.org)
