    A 73-year-old woman presented with chest pain and elevated D-dimers, initially suspected as pulmonary embolism. Transthoracic echocardiography revealed acute type A aortic dissection, emphasizing its diagnostic value and the link between dissection and D-dimer levels.

    Area of Science:

    • Cardiology
    • Diagnostic Imaging
    • Thoracic Surgery

    Background:

    • Chest pain is a common presentation with a broad differential diagnosis.
    • Elevated D-dimers often suggest thromboembolic events like pulmonary embolism.
    • Acute aortic dissection is a life-threatening condition requiring prompt diagnosis.

    Observation:

    • A 73-year-old female with prior coronary artery bypass grafting presented with acute chest pain, hypoxia, and high D-dimer levels.
    • Initial suspicion was acute pulmonary embolism, prompting an urgent transthoracic echocardiogram due to hypotension.
    • Echocardiography unexpectedly revealed an acute type A aortic dissection.

    Findings:

    • Transthoracic echocardiography is a crucial noninvasive tool for evaluating chest pain and suspected pulmonary hypertension.

  • Acute type A aortic dissection can present with elevated D-dimer levels, mimicking pulmonary embolism.
  • The diagnostic utility of echocardiography in identifying aortic dissection in this context is highlighted.

    • Implications:

    • Clinicians should consider aortic dissection in the differential diagnosis of chest pain, especially with elevated D-dimers and hemodynamic instability.
    • Prompt echocardiographic evaluation can expedite diagnosis and management of acute aortic dissection.
    • Understanding the association between aortic dissection and elevated D-dimers is critical for patient care and safety.
