    Area of Science:

    • Cardiology
    • Genetics
    • Valvular Heart Disease

    Background:

    • Mitral valve prolapse (MVP) is the most frequent cardiac valve anomaly in humans.
    • Affecting approximately 4% of the population, MVP is diagnosed via auscultation or echocardiography.
    • Clinical manifestations include palpitations and risks of infective endocarditis or mitral regurgitation.

    Purpose of the Study:

    • To summarize the prevalence, clinical features, and underlying etiology of mitral valve prolapse.
    • To highlight the association between MVP and inherited connective tissue disorders.

    Main Methods:

    • Review of existing clinical and research evidence on mitral valve prolapse.
    • Diagnostic criteria including auscultation (midsystolic clicks, late systolic murmurs) and echocardiography were considered.

    Main Results:

    • Mitral valve prolapse is the most common heart valve abnormality.
    • Associated conditions include thoracic bony abnormalities, reduced body weight, and low blood pressure.
    • MVP carries risks for infective endocarditis and significant mitral regurgitation later in life.

    Conclusions:

    • Mitral valve prolapse is strongly associated with inherited abnormalities in connective tissue.
    • These genetic factors contribute to a spectrum of physical characteristics beyond the mitral valve itself.
