What does a calification means on a unborn fetus heart?

Usually: nothing bad: On the anatomic survey sonogram of the baby's organs, there is a fairly common finding called an echogenic intracardiac focus that looks like a bright spot on the baby's heart, sometimes described as looking like a calcification (calcium deposit in the muscle of the heart). It is considered a 'soft' marker for down syndrome, and very rarely can indicate the baby has down's. More often, baby: fine.
