Continuous fetal hemodynamic monitoring during in-utero surgery is desirable, but it is often not feasible without intermittent interruption. We report the use of a fetal spiral electrode for continuous heart rate monitoring during fetal myelomeningocele repair. Fetal echocardiography and a fetal spiral electrode were used to monitor fetal heart rate during in-utero repair at 25 weeks' gestation. We observed good agreement between echocardiographic and spiral electrode heart rate measurements. Using the Bland-Altman approach, the mean (SD) difference between measurements was 1.8 (3.5) beats per minute with limits of agreement of -5.3 to 8.8 beats per minute. This case illuminates a potential role for a fetal spiral electrode as a real-time adjunct in fetal interventions.
