Two chambered left ventricle. Three new varieties

L M Gerlis, J B Partridge, G I Fiddler

    British Heart Journal
    |September 1, 1981
    PubMed
    Summary

    This review explores the rare two-chambered left ventricle, comparing it to the more common right ventricular variant. Three unique cases highlight diverse subdivisions and potential causes, including congenital heart defects and myocardial sinusoids.

    Area of Science:

    • Cardiology
    • Congenital Heart Disease
    • Cardiac Morphology

    Background:

    • The two-chambered left ventricle is a rare congenital anomaly.
    • It is infrequently compared to the more prevalent two-chambered right ventricle.
    • Understanding its variations is crucial for diagnosis and management.

    Observation:

    • Three distinct cases of left ventricular subdivision are presented.
    • Angiocardiography was instrumental in diagnosing two cases.
    • Associated anomalies included valve dysplasia, endocardial fibroelastosis, and lung malformation.

    Findings:

    • Case 1: Left heart hypoplasia with severe valve stenosis and endocardial fibroelastosis.
    • Case 2: Valve dysplasia, endocardial fibroelastosis, and congenital left lung malformation.

  • Case 3: Unique ventricular subdivision without other congenital defects, possibly an intramyocardial aneurysm.

    • Implications:

    • Highlights the diverse presentations of two-chambered left ventricle.
    • Suggests a role for intertrabecular myocardial sinusoids in pathogenesis.
    • Emphasizes the importance of advanced imaging in diagnosing rare cardiac conditions.
