Mitral-annulus calcification and cerebral or retinal ischaemia

D P de Bono, C P Warlow

    Lancet (London, England)
    |August 25, 1979
    PubMed
    Summary

    Extensive mitral-annulus calcification is linked to cerebral emboli in elderly patients with ischemic symptoms. Echocardiography aids in diagnosing this condition and differentiating it from others.

    Area of Science:

    • Cardiology
    • Neurology
    • Geriatrics

    Background:

    • Cerebral ischemia presents a significant health concern, particularly in the elderly population.
    • Understanding the underlying causes of cerebral ischemia is crucial for effective diagnosis and treatment.

    Observation:

    • A study examined 151 patients with retinal or cerebral ischemia symptoms.
    • Radiological and echocardiographic imaging identified extensive mitral-annulus calcification in 8 patients (aged 64-78).
    • No cases of mitral-annulus calcification were found in 188 matched control subjects.

    Findings:

    • A significant association exists between mitral-annulus calcification syndrome and cerebral emboli.
    • This association is particularly notable in elderly individuals.
    • Echocardiography is an effective noninvasive tool for diagnosing mitral-annulus calcification.

    Implications:

    • Mitral-annulus calcification should be considered in the differential diagnosis of elderly patients presenting with ischemic events.
    • Echocardiography can help identify patients at risk for embolic events due to mitral-annulus calcification.
    • Further research may elucidate the specific mechanisms linking mitral-annulus calcification to cerebral emboli.
