    Severe hyperthyroidism can impair heart function during cesarean delivery, similar to exercise effects in nonpregnant patients. Monitoring left ventricular performance is crucial in these high-risk pregnancies.

    Area of Science:

    • Cardiology
    • Anesthesiology
    • Maternal-Fetal Medicine

    Background:

    • Severely hyperthyroid patients undergoing cesarean delivery present unique anesthetic challenges.
    • Pulmonary artery catheterization is a tool for hemodynamic monitoring in high-risk surgical patients.

    Observation:

    • Hemodynamic monitoring via pulmonary artery catheterization was conducted before cesarean section in a severely hyperthyroid patient.
    • A notable, temporary decrease in left ventricular performance occurred during the operative stress.

    Findings:

    • Surgical stress in hyperthyroid patients undergoing cesarean delivery can transiently impair left ventricular function.
    • The observed cardiac response mirrors findings in nonpregnant hyperthyroid individuals during exercise.

    Implications:

    • This suggests a potential vulnerability of the hyperthyroid heart to surgical stress, even in the context of pregnancy.
    • Careful perioperative cardiac monitoring is essential for managing hyperthyroid patients during cesarean sections.
