Congenital...: ...Means present at birth, and an abnormality is anything that isn't right. Can be something as minor as a skin tag, or as devastating as the vary rare ectopia cordis (heart outside the chest).

Please see below.: Congenital abnormalities are physical differences in the body that are present at birth;each body part has the potential to have an anomaly.Some are genetic, some are due to things that happen in the womb, & some happen for unknown reasons.These differences can vary from minor anomalies (like an extra finger or an ear tag) that don't affect function, to major defects that can be fatal.
