    Summary

    Selective coronary perfusion scintigraphy assesses the heart's terminal vessels, offering crucial insights beyond standard coronarography. This non-invasive imaging technique aids in diagnosing various heart conditions and guiding treatment decisions.

    Area of Science:

    • Cardiology
    • Nuclear Medicine
    • Diagnostic Imaging

    Background:

    • Coronarography visualizes coronary arteries but has limitations in assessing smaller vessels.
    • A need exists for methods evaluating the terminal vascular system of the myocardium.

    Purpose of the Study:

    • To introduce and evaluate selective coronary perfusion scintigraphy.
    • To demonstrate its utility in diagnosing ischemic heart disease and cardiomyopathies.
    • To highlight its role in pre- and post-operative assessment of vascularization surgery.

    Main Methods:

    • Utilizes radioactively labeled microspheres to temporarily occlude arterioles and capillaries.
    • Involves selective coronary perfusion scintigraphy, a minimally invasive procedure.
    • Can be employed as a dual-nuclide method for enhanced information during stress and pharmacological tests.

    Main Results:

    • Selective coronary perfusion scintigraphy provides functional assessment of the terminal vascular system.
    • Identifies perfusion disturbances even in patients with normal coronarograms.
    • Demonstrates effectiveness in diagnosing atypical ischemic heart disease and cardiomyopathies.

    Conclusions:

    • Selective coronary perfusion scintigraphy is a valuable, non-stressful diagnostic tool for myocardial perfusion.
    • It complements coronarography, ventriculography, and bypass surgery assessment.
    • This method expands diagnostic capabilities for complex cardiac conditions.
