[Hemodynamic study of postinfarct left ventricular aneurysm]

A Savova

    Vutreshni Bolesti
    |January 1, 1980
    PubMed
    Summary

    Cardiac aneurysm size impacts left-ventricular function and surgical risk. Aneurysms over 25% of ventricular surface show pathological changes, with high surgical risk above 60%.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Medical Imaging

    Context:

    • Cardiac aneurysms significantly affect left-ventricular function.
    • Assessing aneurysm size and location is crucial for surgical decision-making.
    • Traditional left-ventricular function parameters may be limited in aneurysm patients.

    Purpose:

    • To determine the effect of cardiac aneurysm size and localization on left-ventricular function.
    • To establish indications for surgical treatment based on aneurysm characteristics.
    • To evaluate the significance of local myocardial kinetics in cardiac aneurysm.

    Summary:

    • Thirty-five patients with anterior and posterior cardiac aneurysms underwent comprehensive hemodynamic, angiocardiographic, and coronarographic examination.
    • Cardiac function is pathologically altered in aneurysms exceeding 25% of ventricular surface area, with high surgical risk above 60%.
    • Local kinetics, particularly percentage contraction of cardiac axes, are highly significant for assessing residual myocardium and aneurysm status.

    Impact:

    • Identifies critical aneurysm size thresholds impacting left-ventricular function and surgical risk.
    • Highlights limitations of standard left-ventricular function parameters in cardiac aneurysm.
    • Proposes critical parameter values to guide surgical contraindications and high-risk cases.
