Left atrial appendage aneurysms are rare, often causing arrhythmias and thromboembolism. Surgical resection of the aneurysm, as in this case, provides a curative treatment option for patients.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Medical Case Reports

Background:

  • Left atrial appendage (LAA) aneurysms are rare cardiac anomalies.
  • Patients typically present with symptoms of atrial tachyarrhythmias and thromboembolic events.
  • Surgical intervention is often curative for LAA aneurysms.

Observation:

  • A 60-year-old female with a history of atrial arrhythmias presented with a large LAA aneurysm.
  • The patient also exhibited bi-atrial enlargement and had a family history of arrhythmias.
  • This case highlights a complex presentation of a rare condition.

Findings:

  • The patient was diagnosed with a large left atrial appendage aneurysm.
  • Co-existing bi-atrial enlargement and a family history of arrhythmias were noted.

  • Successful treatment involved surgical resection of the aneurysm.

    • Implications:

    • Surgical resection of LAA aneurysms can be curative.
    • The Cox-Maze III procedure can be combined with aneurysm resection for comprehensive treatment.
    • This case contributes to understanding the management of rare LAA pathologies.
