Congenital heart defects are the most common birth defects, affecting about 1 in 100 babies. These can range from simple issues that may resolve on their own to more complex defects that require ongoing care or surgery.
Early detection is key. Many CHDs are spotted before birth on a prenatal ultrasound, but some aren’t obvious until after delivery. That’s why newborns receive a CHD screening in the nursery, which uses a painless pulse oximetry test to check oxygen levels in the blood. This simple test can help catch serious heart problems early, when treatment is most effective.
Parents know the signs: rapid breathing, blue-tinted lips or skin, poor feeding, or excessive tiredness may warrant prompt evaluation.
