<unk>  (EIF) is a small bright spot seen in the baby’s heart on an ultrasound exam.  This is thought to represent mineralization, or small deposits of calcium, in the muscle of the heart. EIFs are a found in about 3-5% of normal pregnancies and cause no health problems.
EIFs themselves have no impact on health or heart function. Often the EIF is gone by the third trimester. If there are no problems or chromosome abnormalities, EIFs are considered normal changes, or variants.
