A silent giant left atrial enlargement, likely from rheumatic heart disease, caused syncope in a patient. Advanced imaging like echocardiography was crucial for diagnosis when chest X-rays were insufficient.

Area of Science:

  • Cardiology
  • Medical Imaging
  • Rheumatology

Background:

  • Rheumatic heart disease can lead to significant cardiac chamber abnormalities.
  • Silent giant left atrial enlargement presents a diagnostic challenge.
  • Atrial fibrillation is a common complication of left atrial enlargement.

Observation:

  • A 62-year-old woman presented with syncope due to slow atrial fibrillation.
  • She had a history of mild shortness of breath but was otherwise asymptomatic.
  • A 14.5 cm giant left atrial enlargement was identified.

Findings:

  • The cause of the enlargement was likely rheumatic heart disease.
  • Routine chest roentgenogram failed to diagnose the enlarged chamber.
  • Echocardiogram, nuclear angiogram, and computed tomography were essential for diagnosis.

Implications:

  • This case highlights the importance of advanced imaging in diagnosing subtle cardiac conditions.
  • Prompt diagnosis and management of atrial fibrillation are critical in patients with left atrial enlargement.
  • Understanding the link between rheumatic heart disease and giant atrial enlargement aids in patient care.
