Is the newborn heart abnormal serious?

Newborn heart defects are

caused by abnormal development of the heart and great vessels in the fetal period. If it is ventricular septal defect, and the defect area is relatively small, most babies can naturally close within 6 months after birth, generally not serious. However, if the defect area is relatively large, and the child has obvious symptoms, it is relatively serious and needs active treatment.

It is recommended that the child be actively examined after birth and treated according to the severity of the disease.
