Coronary arteriography (CAG) is a gold standard for diagnosing ischemic heart disease (IHD). This review discusses lesion classification, progression/regression, and pitfalls, incorporating newer modalities like IVUS for plaque characterization.

Area of Science:

  • Cardiology
  • Diagnostic Imaging
  • Medical Research

Background:

  • Coronary arteriography (CAG) is a gold standard for diagnosing ischemic heart disease (IHD).
  • Understanding coronary lesion characteristics is crucial for IHD management.
  • Serial CAG allows assessment of lesion progression and regression.

Purpose of the Study:

  • To review the characterization of focal coronary lesions using CAG.
  • To discuss classifications (Rosch's, AHA) and pitfalls in evaluating coronary stenosis.
  • To highlight recent advancements in plaque assessment using IVUS and angioscopy.

Main Methods:

  • Review of existing literature on coronary arteriography and lesion classification.
  • Discussion of serial CAG for assessing lesion changes.

  • Inclusion of information on intravascular ultrasound (IVUS) and angioscopy for plaque characterization.
  • Main Results:

    • CAG provides a gold standard for IHD diagnosis and lesion severity assessment.
    • Rosch's and AHA classifications aid in characterizing coronary lesions.
    • Serial CAG can reveal progression or regression of atherosclerotic lesions.
    • IVUS and angioscopy offer detailed insights into plaque composition (soft, hard, calcification) and intimal thickening.

    Conclusions:

    • CAG remains a cornerstone for IHD diagnosis, with established classification systems.
    • Serial CAG is valuable for monitoring atherosclerotic lesion dynamics.
    • Advanced imaging modalities like IVUS and angioscopy enhance the understanding of coronary plaque characteristics, aiding in risk stratification and treatment decisions.
