    An abnormal mitral leaflet caused severe subaortic stenosis in a child, mimicking a tumor. Surgical resection of the leaflet successfully treated the condition.

    Area of Science:

    • Cardiology
    • Pediatric Cardiology
    • Cardiac Surgery

    Background:

    • Subaortic stenosis (SAS) is a common cause of left ventricular outflow tract obstruction in children.
    • Diagnosis often involves echocardiography, cardiac catheterization, and angiography.
    • Differential diagnosis for left ventricular outflow tract masses includes tumors and congenital anomalies.

    Observation:

    • A 5-year-old boy presented with a systolic heart murmur.
    • Cardiac catheterization revealed significant subaortic stenosis with a 90 mmHg peak systolic pressure gradient.
    • Left ventricular angiography demonstrated a tumor-like structure within the outflow tract.

    Findings:

    • Intraoperative findings identified the mass as an abnormal, bulky accessory mitral leaflet.

  • Histopathological examination confirmed the leaflet's abnormal morphology.
  • Successful surgical resection of the accessory mitral leaflet was performed.

    • Implications:

    • This case highlights an uncommon etiology of subaortic stenosis.
    • Accurate diagnosis is crucial for appropriate surgical management.
    • Early detection and intervention can lead to favorable outcomes in pediatric SAS.
