Echocardiographic features of mitral annulus calcification

N Dashkoff, M Karacuschansky, P C Come

    American Heart Journal
    |November 1, 1977
    PubMed
    Summary

    Echocardiography reveals distinct patterns for mitral annulus calcification (MAC), aiding diagnosis. Recognizing these echocardiographic findings helps differentiate MAC from other cardiac conditions.

    Area of Science:

    • Cardiology
    • Medical Imaging
    • Echocardiography

    Background:

    • Mitral annulus calcification (MAC) is a common finding.
    • Distinct echocardiographic patterns associated with MAC are not widely recognized.
    • Differentiating MAC from other cardiac abnormalities can be challenging.

    Purpose of the Study:

    • To describe the characteristic echocardiographic patterns of mitral annulus calcification (MAC).
    • To highlight how echocardiography can aid in the diagnosis and differentiation of MAC.
    • To emphasize the clinical significance of recognizing MAC on echocardiograms.

    Main Methods:

    • Retrospective analysis of echocardiograms from ten patients with roentgenographically confirmed mitral annulus calcification (MAC).
    • Correlation of echocardiographic findings with cardiac catheterization, intraoperative findings, and pathological data.
    • Detailed description of M-mode echocardiographic features, including echo density and mitral valve leaflet motion.

    Main Results:

    • Distinctive echocardiographic patterns were observed in all ten patients with MAC.
    • A dense band of echoes in the mitral annulus region was a consistent finding.
    • Echocardiography identified coexisting aortic valve or papillary muscle calcification in some patients.
    • Specific echocardiographic findings could mimic other conditions like pericardial effusion or mitral stenosis.

    Conclusions:

    • Echocardiography is a valuable tool for identifying and characterizing mitral annulus calcification (MAC).
    • Recognition of MAC's echocardiographic patterns can prevent misdiagnosis of other cardiac abnormalities.
    • Understanding these patterns improves diagnostic accuracy in patients with suspected or confirmed MAC.
