Can congenital funnel chest be detected during prenatal examinations?

Congenital funnel chest can generally be detected during prenatal examinations. A four-dimensional color ultrasound is required during routine antenatal checkups, which can determine whether the fetus has congenital funnel chest. Congenital funnel chest may be associated with calcium deficiency; therefore, pregnant women should consume more calcium-rich foods. If necessary, calcium supplements should be taken as directed by a physician to promote fetal skeletal growth and development.
