    Intracoronary scintigraphy (IS) complements coronary angiography by evaluating myocardial perfusion. IS is crucial for assessing bypass surgery candidates, bypassed patients, and those with angina despite normal coronary angiography.

    Area of Science:

    • Cardiology
    • Nuclear Medicine
    • Diagnostic Imaging

    Background:

    • Coronary angiography provides morphological information but may not fully assess myocardial perfusion.
    • Evaluating myocardial perfusion is essential for diagnosing and managing coronary artery disease.

    Purpose of the Study:

    • To compare intracoronary scintigraphy (IS) with coronary angiography in patients undergoing evaluation for coronary artery disease.
    • To determine the added value of IS in assessing myocardial perfusion.

    Main Methods:

    • 30 patients undergoing coronary angiography were also studied using intracoronary scintigraphy (IS).
    • Scintigraphic and angiographic data were compared to assess concordance and discordance.

    Main Results:

    Related Experiment Videos

    • 21 cases showed concordant results (normal or pathological).
    • 6 cases had pathological angiography with normal IS, indicating normal myocardial perfusion.
    • 3 cases had normal angiography with pathological IS, revealing arteriolar-capillary system damage.

    Conclusions:

    • Intracoronary scintigraphy (IS) accurately evaluates myocardial perfusion, complementing coronary angiography.
    • IS is valuable for bypass surgery candidates, assessing bypassed patients, and diagnosing arteriolar-capillary system damage in patients with typical angina and normal coronary angiography.
