    A rare case of left ventricular diverticulum near the aortic valve was treated with valve replacement and surgical closure. This non-atherosclerotic diverticulum featured unusual location and calcification.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Pathology

    Background:

    • Left ventricular diverticulum (LVD) is a rare congenital or acquired cardiac anomaly.
    • It can lead to heart failure, arrhythmias, and thromboembolic events.
    • Aortic valve ring proximity is an uncommon LVD location.

    Observation:

    • A patient presented with symptoms of aortic insufficiency and stenosis.
    • Imaging revealed a left ventricular diverticulum situated directly beneath the aortic valve ring.
    • The diverticulum wall exhibited calcification, and its etiology was non-atherosclerotic.

    Findings:

    • Surgical intervention included aortic valve replacement and diverticulum closure.
    • Histopathological examination confirmed the non-atherosclerotic nature and calcification of the diverticulum.

  • Successful management of this complex cardiac anomaly was achieved.

    • Implications:

    • This case highlights the importance of considering rare cardiac pathologies in patients with valvular disease.
    • Surgical repair of LVDs, even in unusual locations with calcification, is feasible.
    • Understanding non-atherosclerotic etiologies of LVD is crucial for diagnosis and treatment.
