Isolated coronary ostial stenosis.

G A Miller, M Honey, H el-Sayed

    Catheterization and Cardiovascular Diagnosis
    |January 1, 1986
    PubMed
    Summary

    This study identifies a distinct syndrome in five female patients with angina pectoris caused by left coronary ostial stenosis. This condition differs significantly from typical atherosclerotic coronary artery disease.

    Area of Science:

    • Cardiology
    • Vascular Medicine
    • Diagnostic Imaging

    Background:

    • Coronary artery disease (CAD) typically affects males, with a 7:1 male:female ratio.
    • Atherosclerotic CAD commonly involves multiple coronary arteries.
    • Left main coronary artery ostial stenosis is a rare condition.

    Observation:

    • Five female patients aged 38-53 presented with typical angina pectoris.
    • All patients had isolated left coronary ostial stenosis.
    • No evidence of other coronary or aortic diseases (e.g., Takayasu aortitis) was found.

    Findings:

    • The observed patient group exhibited a unique demographic profile, contrasting with typical CAD populations.
    • Angiographic diagnosis of ostial stenosis can be challenging.
    • Key diagnostic indicators include a pressure gradient across the ostium and absent contrast spill into the sinus of Valsalva.

    Implications:

    • These findings suggest a potentially rare, distinct clinical syndrome of isolated left coronary ostial stenosis.
    • Recognition of specific angiographic signs is crucial for accurate diagnosis.
    • Further research is warranted to understand the etiology and optimal management of this condition.
