[Functional aortic systolic murmurs in the elderly].

    Summary

    Functional systolic murmurs in elderly patients are often caused by aortic valve calcification or aortic dilatation, not aortic stenosis. These "innocent" murmurs can be distinguished from pathological murmurs by specific clinical and phonocardiographic features.

    Area of Science:

    • Cardiology
    • Geriatrics
    • Pathology

    Context:

    • Elderly patients often present with systolic murmurs.
    • Distinguishing functional murmurs from pathological aortic stenosis is clinically important.
    • Previous terminology like "mitro-aortic murmur" may be misleading.

    Purpose:

    • To clinically and phonocardiographically characterize functional aortic systolic murmurs in the elderly.
    • To differentiate these murmurs from true aortic stenosis.
    • To identify the underlying causes of these functional murmurs.

    Summary:

    • Functional aortic systolic murmurs in 26 elderly patients were studied.
    • Key differentiating features include absence of thrill, murmur characteristics, aortic sound changes, and normal arteriogram.

    Related Experiment Videos

  • Pathological confirmation in 19 patients revealed aortic valve calcification and/or ascending aorta dilatation without stenosis.

    • Impact:

    • Provides criteria to differentiate innocent systolic murmurs from aortic stenosis in the elderly.
    • Suggests that "innocent" murmurs result from age-related changes like calcification or dilatation.
    • Recommends discontinuing the term "mitro-aortic murmur".
