[Ventricular pseudoaneurysm after acute myocardial infarction].

C Christensen

    Ugeskrift for Laeger
    |February 27, 1989
    PubMed
    Summary

    Left ventricular aneurysm, a complication of myocardial infarction, can be true or false. False aneurysms (pseudoaneurysms) are rare but prone to rupture, requiring early diagnosis via echocardiography.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Medical Imaging

    Background:

    • Left ventricular aneurysm is a frequent complication following myocardial infarction.
    • True aneurysms involve all ventricular wall layers, forming a large sac.
    • False aneurysms (pseudoaneurysms) arise from myocardial rupture, creating a sac without myocardial elements.

    Observation:

    • Pseudoaneurysms present as a narrow-necked channel connecting the ventricle to a sac of clot and pericardial tissue.
    • These rare aneurysms have a significant tendency to rupture.
    • Early diagnosis is crucial due to the potential for successful surgical repair.

    Findings:

    • Two-dimensional echocardiography combined with Doppler-flow imaging is the primary diagnostic method.
    • Distinguishing pseudoaneurysms from true aneurysms is vital for patient management.

    Implications:

    • Prompt diagnosis of left ventricular pseudoaneurysms can lead to timely surgical intervention.
    • Improved diagnostic accuracy through echocardiography enhances patient outcomes after myocardial infarction.
