Identifying severe aortic valvular stenosis by bedside examination.

G Forssell, R Jonasson, E Orinius

    Acta Medica Scandinavica
    |January 1, 1985
    PubMed
    Summary

    Bedside examination by a cardiologist accurately predicts aortic stenosis (AS) severity. Effort syncope and murmur intensity are key indicators, reducing the need for invasive tests in many AS patients.

    Area of Science:

    • Cardiology
    • Diagnostic Medicine
    • Clinical Assessment

    Background:

    • Aortic stenosis (AS) diagnosis often requires invasive procedures.
    • Accurate non-invasive assessment is crucial for patient management.

    Purpose of the Study:

    • To evaluate the predictive value of bedside clinical examination for significant aortic stenosis (AS).
    • To assess the accuracy of specific symptoms and physical findings in diagnosing AS severity.

    Main Methods:

    • Prospective examination of 67 symptomatic AS patients by senior cardiologists.
    • Analysis of predictive values for effort syncope and murmur characteristics.
    • Validation of a combined clinical criteria set on 39 additional AS patients.

    Main Results:

    • Effort syncope had 100% positive predictive value for significant AS.
    • Combining effort syncope and mid-systolic murmur intensity yielded 90% positive and 94% negative predictive values.
    • Low inter-observer variation was observed for key clinical findings.

    Conclusions:

    • Bedside cardiac examination by experienced cardiologists is highly predictive of AS severity.
    • Clinical assessment can effectively guide management, potentially reducing reliance on invasive diagnostics.
    • Non-invasive tests serve a supplementary role; invasive procedures remain necessary for conditions like effort angina.
