Coronary Ostial Stenosis

A Coronary Ostial Stenosis is a vascular stenosis that occurs at the coronary ostial origin where coronary ostial vessels branch from the coronary ostial aorta.

• AKA: Ostial Coronary Lesion, Coronary Ostium Stenosis, Aorto-Ostial Stenosis.
• Context:
  • It can typically impair Coronary Ostial Blood Flow through coronary ostial luminal narrowing.
  • It can typically require Coronary Ostial Specialized Intervention using coronary ostial technical approaches.
  • It can typically present Coronary Ostial Technical Challenges for coronary ostial percutaneous treatment.
  • It can typically affect Coronary Ostial Hemodynamic Function more than coronary ostial non-ostial lesions.
  • It can typically involve Coronary Ostial Plaque Morphology with coronary ostial unique characteristics.
  • ...
  • It can often necessitate Coronary Ostial Dedicated Stents for coronary ostial optimal outcomes.
  • It can often require Coronary Ostial Intravascular Imaging for coronary ostial precise assessment.
  • It can often benefit from Coronary Ostial Cutting Balloons during coronary ostial lesion preparation.
  • It can often need Coronary Ostial Guide Catheter Techniques for coronary ostial stable engagement.
  • ...
  • It can range from being a Mild Coronary Ostial Stenosis to being a Critical Coronary Ostial Stenosis, depending on its coronary ostial severity percentage.
  • It can range from being a Focal Coronary Ostial Stenosis to being a Diffuse Coronary Ostial Stenosis, depending on its coronary ostial lesion extent.
  • ...
  • It can require Coronary Ostial FFR Assessment for coronary ostial functional significance.
  • It can utilize Coronary Ostial IVUS Guidance for coronary ostial intervention optimization.
  • It can benefit from Coronary Ostial OCT Imaging for coronary ostial plaque characterization.
  • ...
• Example(s):
  • Coronary Ostial Stenosis Locations, such as:
    • Right Coronary Ostial Stenosis at the coronary ostial rca origin.
    • Left Main Coronary Ostial Stenosis at the coronary ostial lmca origin.
    • Saphenous Vein Graft Ostial Stenosis at the coronary ostial svg anastomosis.
  • Coronary Ostial Stenosis Etiologys, such as:
    • Atherosclerotic Coronary Ostial Stenosis from coronary ostial plaque accumulation.
    • Aortic Valve-Related Coronary Ostial Stenosis from coronary ostial aortic pathology.
    • Post-Surgical Coronary Ostial Stenosis following coronary ostial cardiac surgery.
  • Coronary Ostial Stenosis Treatments, such as:
    • Coronary Ostial Stenting Procedure with coronary ostial dedicated devices.
    • Coronary Ostial Surgical Bypass using coronary ostial arterial grafts.
    • Coronary Ostial Rotational Atherectomy for coronary ostial calcified lesions.
  • ...
• Counter-Example(s):
  • Coronary Mid-Vessel Stenosis, which occurs in coronary vessel body rather than coronary ostial location.
  • Coronary Bifurcation Stenosis, which affects coronary branch points rather than coronary ostial origin.
  • Coronary Distal Stenosis, which involves coronary terminal segments rather than coronary ostial beginning.
