    Summary

    This study assessed myocardial perfusion in Vineberg implants using radioactive tracers. Patent implants showed even tracer distribution, indicating good blood flow to the heart muscle.

    Area of Science:

    • Cardiology
    • Nuclear Medicine
    • Surgical Innovation

    Background:

    • Vineberg implants are a surgical technique to improve myocardial perfusion.
    • Assessing the long-term efficacy of these implants is crucial for patient outcomes.

    Purpose of the Study:

    • To evaluate myocardial perfusion in patients with Vineberg implants using nuclear imaging.
    • To correlate scintigraphic findings with internal mammary arteriography.

    Main Methods:

    • Seven patients, 6 years post-Vineberg procedure, underwent selective contrast arteriography.
    • Radioactive tracers (99mTc and 131I-MAA) were injected into internal mammary implants.
    • Myocardial scintigraphy was performed and correlated with arteriographic results.

    Main Results:

    • Patent Vineberg implants with good communication demonstrated even distribution of radioactive tracers.
    • This even distribution on myocardial scintigrams reflects effective perfusion at the capillary or precapillary level.

    Conclusions:

    • Vineberg implants can achieve effective myocardial perfusion.
    • Nuclear imaging combined with arteriography is a valuable method for assessing implant patency and perfusion.
