    A left atrial myxoma adhered to the mitral valve, mimicking mitral valve motion on M-mode echocardiography. Cross-sectional echocardiography enabled accurate diagnosis, later confirmed by surgery.

    Area of Science:

    • Cardiology
    • Medical Imaging
    • Surgical Pathology

    Background:

    • Left atrial myxomas are the most common primary cardiac tumors.
    • Myxomas can cause significant embolic and obstructive complications.
    • Accurate preoperative diagnosis is crucial for effective surgical management.

    Observation:

    • A left atrial myxoma was found adhered to the anterior mitral valve leaflet.
    • The tumor's stalk movement mimicked mitral valve motion on M-mode echocardiography.
    • This presentation posed a diagnostic challenge using initial imaging modalities.

    Findings:

    • Cross-sectional echocardiography provided detailed visualization of the myxoma's attachment and mobility.
    • The diagnostic accuracy of cross-sectional echocardiography was confirmed during surgical intervention.

  • The study highlights a specific echocardiographic manifestation of a left atrial myxoma.

    • Implications:

    • Improved understanding of rare echocardiographic presentations of cardiac myxomas.
    • Enhanced diagnostic capabilities for intracardiac tumors.
    • Guidance for surgical planning and risk assessment in patients with cardiac masses.
