4 Fetal monitoring prior to surgery shows a baseline of 140 and moderate variability; continuous fetal monitoring during bypass and baseline of 130 with moderate variability. During aortic clamp the fetal heart rate ranged between 180 and 60 beats/min; a non-stress test NST monitoring was made at the end of the surgery, it was reactive.
