    Chronic aortic dissections, a rare condition, often present subtly with cardiac failure rather than pain. These dissections can mimic atherosclerotic aneurysms on imaging, leading to incidental discovery during angiography.

    Area of Science:

    • Cardiovascular Medicine
    • Vascular Surgery
    • Diagnostic Imaging

    Background:

    • Chronic aortic dissections represent 10% of all aortic dissection cases.
    • These dissections typically originate distal to the left subclavian artery.
    • They are characterized by reentry points into the true lumen.

    Observation:

    • Patients with chronic dissections may experience minimal or absent pain.
    • Cardiac failure is a common presenting symptom.
    • Radiographically, chronic dissections can resemble atherosclerotic aneurysms on chest films.

    Findings:

    • Four cases of chronic aortic dissections were incidentally discovered during angiography.
    • The study highlights the varied presentation of chronic aortic dissections.

  • Diagnostic imaging plays a crucial role in identifying these subtle conditions.

    • Implications:

    • Increased awareness of chronic aortic dissections is needed among clinicians.
    • Angiography can reveal these conditions when they present atypically.
    • Further research into the long-term management of chronic aortic dissections is warranted.
