Persistent fetal circulation. Two cases with myocardial dysfunction and severe acidosis

D J Radford

    The Medical Journal of Australia
    |January 13, 1979
    PubMed
    Summary

    Severe persistent fetal circulation in neonates can mimic congenital heart disease. Medical management led to survival and resolution of cardiac and pulmonary abnormalities.

    Area of Science:

    • Neonatal cardiology
    • Pediatric critical care

    Background:

    • Persistent fetal circulation (PFC) is a critical neonatal condition.
    • Severe PFC can present with complex cardiopulmonary dysfunction.

    Observation:

    • Two neonates exhibited severe PFC, mimicking congenital heart disease.
    • Key features included pulmonary hypertension, right-to-left shunting via ductus arteriosus, poor myocardial contractility, and atrioventricular valve regurgitation.
    • Extreme acidaemia was also noted.

    Findings:

    • Neonates with severe PFC and cardiac dysfunction survived.
    • Functional abnormalities, including pulmonary hypertension and shunting, resolved with medical management.

    Implications:

    • This case series highlights the potential for medical management in severe PFC.
    • Early recognition and intervention are crucial for improving outcomes in neonates with PFC.
    • Further research into the pathophysiology and treatment of severe PFC is warranted.
