Abstract: according to the children with congenital heart disease are cyanotic congenital heart disease symptoms can be divided into three types: latent cyanosis, non cyanotic, cyanosis.

Congenital heart disease, doctors often referred to as congenital heart disease. Congenital heart disease is not uncommon, the incidence rate is about 7 per thousand live births born -8%, is the mother in the early stages of pregnancy (embryo) due to the formation of a cardiovascular heart vascular dysplasia and malformations, is the most common heart disease in infants.

According to whether children with congenital heart disease symptoms appear cyanotic congenital heart disease can be divided into three types:

Latent cyanosis (right and left to shunt): this type is between the left and right sides of the heart blood circulation pathway channel. The left half of the body due to early cardiac cycle pressure is greater than the right side pulmonary circulation pressure, so usually flow from left to right shunt without bruising. When crying, breath or any pathology, resulting in pulmonary artery or right ventricular pressure, left ventricular pressure and over, can make blood from right to left shunt and temporary cyanosis. Such as atrial septal defect, ventricular septal defect, patent ductus arteriosus, etc..

Non cyanotic: low oxygen right heart does not enter the left heart, no cyanosis. Such as pulmonary stenosis, aortic stenosis, coarctation of the aorta, simple pulmonary artery dilatation, primary pulmonary hypertension, etc..

Cyanotic (right to left shunt): children with this type of congenital heart disease in infants with congenital heart disease typical symptoms of persistent cyanosis, abnormal passage between children with this type of congenital heart disease on both sides of blood circulation, blood flow from the left to right heart cavity, a lot of venous blood into the systemic circulation, so children with persistent cyanosis phenomenon. Such as tetralogy of Fallot, trilogy of Fallot, transposition of the great vessels etc..

If parents find their children with the symptoms of congenital heart disease in infants, should be early to the hospital, to be diagnosed with congenital heart disease, inspection methods are commonly used X-ray, ECG, echocardiography, heart to heart catheterization and angiography examination. Once diagnosed with congenital heart disease, cardiac surgical treatment as soon as possible to be determined by the doctor, timing of surgery, cardiac surgery is now developing very fast, the operation change rapidly most of congenital heart disease, has become completely cured of the disease.
