congenital

 [kon-jen´ĭ-t'l]
existing at, and usually before, birth; referring to conditions that are present at birth, regardless of their causation. Cf. hereditary.
congenital heart defect a structural defect of the heart or great vessels or both, present at birth. Any number of defects may occur, singly or in combination. They result from improper development of the heart and blood vessels during the prenatal period. Congenital heart defects occur in about 8 to 10 of every 1000 live-born children in the United States. The most common types are tetralogy of fallot, patent ductus arteriosus, ventricular septal defect, atrial septal defect, transposition of great vessels, and coarctation of the aorta.

In many cases, depending on the severity of the defect and the physical condition of the patient, these congenital conditions can be treated by surgery. However, some are so minor that they do not significantly affect the action of the heart and do not require surgery. The cause of most of these conditions is unknown. Gene abnormalities account for about 5 per cent, and in a small number of other cases they may be seen in a child whose pregnant mother had rubella (German measles) during the first 2 or 3 months of pregnancy.

Patient discussion about Congenital

Q. What is the treatment for an arachnoid cyst? My 15 year old son has just been diagnosed with an arachnoid cyst. What is the treatment? Is an operation necessary?

A. An operation is not always necessary, it depends on the size and location of the cyst. I suggest you take your son to a neurologist or a neurosurgeon for further consult.
