Intermittent mitral regurgitation: an indicator of severe Beall valve dysfunction.

R J Coralli, E R Dorney, P F Walter

    Clinical Cardiology
    |July 1, 1987
    PubMed
    Summary

    Teflon discs in Beall valves experience significant wear. Intermittent mitral regurgitation in patients with these valves indicates severe dysfunction, requiring prompt cardiac catheterization and valve replacement.

    Area of Science:

    • Cardiovascular Surgery
    • Biomaterials Science

    Background:

    • Beall valves, utilizing Teflon discs, are prone to wear and tear.
    • Monitoring patients with Beall valves for dysfunction is clinically essential.

    Purpose of the Study:

    • To highlight the clinical significance of intermittent mitral regurgitation in patients with Beall valves.
    • To correlate this auscultatory finding with severe Teflon disc wear and abnormal valve function.

    Main Methods:

    • Case series describing 4 patients with Beall valves.
    • Clinical auscultation for mitral regurgitation.
    • Cardiac catheterization to assess valve disc function.

    Main Results:

    • All 4 patients presented with intermittent mitral regurgitation.

    Related Experiment Videos

  • Severe wear of the Teflon disc was observed in all cases.
  • Abnormal, intermittent disc tilting was confirmed via cardiac catheterization.

    • Conclusions:

    • Intermittent mitral regurgitation is a critical sign of severe Beall valve dysfunction.
    • Urgent cardiac catheterization and valve replacement are indicated upon detecting this finding.
