An anatomical feature or defect is called congenital when it existed at birth. Many congenital defects (such as a hole between the two main chambers of the heart) are common and have symptoms that make the condition easy to diagnose. However, rare defects in the soft tissues (such as the third ostium in Human Error) are often impossible to find unless the doctor knows specifically where to look.
