    Core cooling successfully interrupted a cycle of low cardiac output, vasoconstriction, and hyperthermia in a patient with severe heart valve stenosis. This suggests low cardiac output may contribute to severe hyperthermia in critical illness.

    Area of Science:

    • Cardiology
    • Critical Care Medicine
    • Medical Physiology

    Background:

    • Severe aortic and mitral stenosis can lead to complex cardiovascular complications.
    • Understanding the interplay between cardiac output and core body temperature is crucial in managing critically ill patients.

    Observation:

    • A patient with end-stage valve stenosis presented with a cycle of low cardiac output, peripheral vasoconstriction, and rising core temperature.
    • This clinical deterioration progressed to cardiac decompensation.

    Findings:

    • Core cooling via iced gastric lavage effectively interrupted the patient's hyperthermia and associated symptoms.
    • The patient's severe hyperthermia was hypothesized to be caused or exacerbated by her compromised cardiac output.

    Implications:

    • Core cooling is a potential therapeutic intervention for managing hyperthermia in patients with low cardiac output.
    • Further research is warranted to elucidate the relationship between cardiac dysfunction and thermoregulation in critical care settings.
