Annular sub-mitral aneurysms are rare cardiac defects. This case report details a calcified variant, emphasizing pre-operative imaging and surgical considerations for successful management.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Medical Imaging

Background:

  • Annular sub-mitral aneurysms are uncommon cardiac lesions with diverse causes.
  • A sub-mitral membrane may predispose individuals to aneurysm formation.
  • These aneurysms originate from the atrioventricular groove, near the mitral valve's mural leaflet.

Observation:

  • The case involves a calcified, bi-lobed sub-mitral aneurysm with a left atrial connection.
  • Lesions can cause mass effects, mitral regurgitation, and impaired left ventricular function.
  • Surgical repair is complex due to proximity to the circumflex artery, atrioventricular junction, and mitral valve.

Findings:

  • Computed tomogram angiography is crucial for detailed pre-operative anatomical assessment.

  • Understanding the anatomical basis is key to managing these rare aneurysms.
  • The report highlights the surgical approach for this specific calcified variant.

    • Implications:

    • Accurate pre-operative imaging aids in planning complex cardiac surgeries.
    • Improved understanding of sub-mitral aneurysm anatomy can refine surgical techniques.
    • This case contributes to the literature on rare cardiac pathologies and their management.
