Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Pathology

Background:

  • Annular subvalvular left ventricular aneurysm, first described in 1962, typically originates from the subaortic or submitral regions.
  • Differentiating these aneurysms from false aneurysms caused by myocardial necrosis is crucial.
  • The exact cause of subvalvular aneurysms remains largely unknown.

Observation:

  • A case of annular submitral left ventricular aneurysm is presented.
  • The patient had no prior history of coronary artery disease.
  • Diagnostic imaging, including two-dimensional echocardiography and magnetic resonance imaging (MRI), revealed a large left ventricular aneurysm.

Findings:

  • The diagnosis of annular submitral left ventricular aneurysm was definitively established through open-heart surgery.

  • Pathological examination further confirmed the presence and nature of the aneurysm.

    • Implications:

    • This case contributes to the understanding of annular submitral left ventricular aneurysms.
    • It underscores the importance of advanced imaging techniques in diagnosis.
    • Further research into the etiology of subvalvular aneurysms is warranted.
