A routine pre-natal ultrasound detects a life-threatening heart defect in a fetus prior to delivery. Standard care, allowing the fetus to come to deliver and then repairing the defect, is associated with significant fetal and neonatal morbidity and mortality. There is an experimental in utero surgical procedure that may have less morbidity and mortality. Which of the following is true?
1) The experimental in utero surgical procedure is associated with increased fetal and neonatal morbidity and mortality compared to standard care.
2) Standard care involves repairing the heart defect after delivery, which is less invasive and safer for both the fetus and the mother.
3) The experimental in utero surgical procedure offers potential benefits of reducing fetal and neonatal morbidity and mortality compared to standard care.
4) Prenatal ultrasound is not reliable for detecting life-threatening heart defects in fetuses.
