A fetus with a right aortic arch that has a normal cardiac structure and a simple vascular alignment abnormality usually has no effect on the fetus and is born essentially the same as a normal fetus. If there is a cardiac abnormality or a chromosomal disorder, the fetus will have a higher postnatal mortality rate. The specific condition of a fetus born with a right aortic arch varies from person to person. Right aortic arch is a congenital malformation, but it is also a congenital heart disease with a high survival rate. Generally, if there is no obvious abnormality in the heart, it will not affect the life of the fetus after birth. Therefore, for fetuses with right-sided aortic arch, it is recommended to follow the doctor’s instructions to carry out the relevant programs to determine whether the pregnancy can continue according to the results of the examination.
