    In mitral stenosis patients, echocardiography revealed abnormal left ventricular function in 19%. Dilated ventricles strongly correlate with impaired cardiac performance, suggesting myocardial damage.

    Area of Science:

    • Cardiology
    • Echocardiography
    • Cardiac Physiology

    Context:

    • Mitral stenosis is a significant valvular heart disease.
    • Left ventricular (LV) function assessment is crucial for patient management.
    • M-mode echocardiography offers insights into cardiac mechanics.

    Purpose:

    • To evaluate left ventricular performance in patients with pure mitral stenosis.
    • To identify echocardiographic subsets based on LV dimensions.
    • To correlate LV dimensions with ventricular function in mitral stenosis.

    Summary:

    • This M-mode echocardiographic study analyzed 40 pure mitral stenosis patients.
    • Abnormal LV function was observed in 19%, categorized into small, normal, and dilated LV dimensions.
    • The dilated LV subset showed significantly impaired end-systolic dimensions (71.4%) and poor ventricular performance, indicative of myocardial damage from rheumatic carditis.

    Impact:

    • Highlights the association between dilated LV and poor ventricular performance in mitral stenosis.
    • Emphasizes the importance of identifying dilated LV subset for risk stratification.
    • Suggests that detecting impaired LV function may influence surgical treatment decisions.
