At birth, there is an abnormality of the heart structure known as congenital heart disease, such as atrial septal defect between the right and left atrial septal defect, right ventricular septal defect with the left ventricular septal defect.

All valves can be narrowed or blocked, such as pulmonary stenosis, aortic stenosis. Also one side of ventricular dysplasia or absent, such as left ventricular dysplasia, single ventricle.

The cardiac cavity and the connection between the arteries and veins can also be abnormal, such as complete transposition of the great arteries, complete or partial anomalous pulmonary venous drainage. A variety of abnormalities may also exist at the same time, such as tetralogy of Fallot.

Congenital heart disease is the most common cardiovascular disease in children, generally under the age of 3 can be confirmed. Congenital heart disease in children is mainly due to the early development of the fetus, the fetus is generally the first 3 months, due to some reasons for the development of fetal cardiovascular standstill or abnormal.

The reason is recognized as pregnant women suffering from rubella, influenza virus infection; pregnant women taking hormone drugs or other fetal damage; pregnant women's abdominal or pelvic by X-ray, ultrasonic, radionuclide exposure; or lack of nutrition, pregnant women with severe hypoxia.

Some children in congenital heart disease, accompanied by systemic multiple malformations, which often indicate that children due to genetic defects and germ cells in congenital heart disease.

Mild congenital heart disease can have no special symptoms, normal growth and development, only in the physical examination found in the left chest loud noise.

Heavy heart patients with obvious symptoms that occur early in the neonatal period or infancy.
