[Congenital thyroid abnormality (subhyoid ectopy) associated with mitral valve prolapse]

A Paggi, L Coppotelli, C Astarita

    Minerva Medica
    |May 7, 1982
    PubMed
    Summary

    This study details a rare case of sub-hyoid thyroid ectopy, a congenital anomaly. Echocardiography revealed hypothyroidism and mitral valve prolapse, which improved with thyroid hormone therapy.

    Area of Science:

    • Cardiology
    • Endocrinology
    • Medical Imaging

    Background:

    • Congenital anomalies of the thyroid gland, such as ectopy, are rare and can present with diverse clinical manifestations.
    • Hypothyroidism, often associated with thyroid dysfunction, can lead to significant cardiovascular complications.
    • Echocardiography is a crucial non-invasive tool for assessing cardiac structure and function.

    Observation:

    • A 35-year-old woman presented with symptoms of hypothyroidism and was diagnosed with sub-hyoid thyroid ectopy.
    • Echocardiographic examination revealed a mesosystolic prolapse of the posterior mitral valve leaflet.
    • The patient also exhibited echocardiographic findings consistent with myxedematous cardiomyopathy.

    Findings:

    • Sub-hyoid thyroid ectopy was confirmed as the underlying cause of the patient's hypothyroidism.

    Related Experiment Videos

  • The echocardiogram demonstrated significant mitral valve prolapse and myxedematous cardiomyopathy.
  • Thyroid hormone replacement therapy (opotherapy) led to the resolution of the cardiac abnormalities.

    • Implications:

    • This case highlights the importance of considering rare congenital anomalies in the differential diagnosis of hypothyroidism.
    • Echocardiography plays a vital role in identifying and monitoring cardiovascular complications associated with thyroid dysfunction.
    • Successful thyroid opotherapy can reverse cardiac manifestations of myxedematous cardiomyopathy, underscoring the link between endocrine and cardiovascular health.
