    Summary

    Two-dimensional echocardiography accurately diagnoses type A aortic dissection, involving the ascending aorta. This imaging technique offers a safe, rapid alternative to angiography for surgical planning.

    Area of Science:

    • Cardiology
    • Diagnostic Imaging
    • Thoracic Surgery

    Background:

    • Type A aortic dissection requires prompt diagnosis for surgical intervention.
    • Conventional diagnosis often relies on angiography, which carries risks.
    • Two-dimensional echocardiography (2D-echo) is a non-invasive imaging modality.

    Purpose of the Study:

    • To evaluate the diagnostic accuracy and clinical utility of 2D-echo for type A aortic dissection.
    • To assess if 2D-echo can expedite surgical decision-making.

    Main Methods:

    • Retrospective review of 10 patients with type A aortic dissection.
    • Six patients underwent early 2D-echo evaluation.
    • Findings correlated with surgical or autopsy results.

    Main Results:

    • 2D-echo correctly identified intimal flaps or false lumens in 4 out of 6 patients.
    • Suggestive findings (aortic enlargement, pericardial effusion) were noted in 2 patients.
    • Surgical confirmation of all echocardiographic and angiographic findings.

    Conclusions:

    • 2D-echo provides a quick, accurate, and safe method for diagnosing ascending aortic dissection.
    • Visualization of specific features (intimal flap, false lumen) allows for immediate surgical intervention, avoiding aortography risks.
