According to statistics, about 6 of every 1000 newborns suffering from congenital heart disease. According to the birth rate and incidence of CHD, estimated each year in China 150 thousand in the birth. Congenital heart disease is a killer of children and adults' health and life".
Our CHD prevalence has decreased with age trend of birth was 6.87 per thousand live births (Shanghai), 3.1 preschool children in 1000 (Chengdu), 2.39 school-age children% ~ 2.8 per thousand (Hefei, Fuzhou), 3.1 middle school students and primary school (Harbin)%, 1.08 per thousand adults (Guangdong). However, in the plateau area of primary and middle school students in Qinghai, the prevalence rate of up to 8.8 per thousand to 13.7 per thousand. American born infant survival prevalence rate of about 8 per thousand, stillbirth prevalence rate of 80 per thousand, the prevalence rate of adults was 2.4 per thousand to 2.8 per thousand (Flemming John, Chicago).
The optimal time of treatment depends on many factors, including the complexity of congenital malformation, the age and weight of the children, the development of the whole body and the nutritional status. A simple congenital heart, 1--5 years old, because the age is too small, low weight, body development and nutrition status of the poor, will increase the risk of surgery; age is too large, the heart will be compensatory increase, some even higher the pulmonary arterial pressure, will also increase the difficulty of the operation, postoperative recovery time is longer. For patients with pulmonary hypertension, congenital malformations and serious impact on the growth and development of children with congenital deformity of life, complex deformity surgery need to be phased as early as possible, not limited by age.
Complex congenital heart disease, should be as early as possible to do the surgery, but in general, the risk of surgery under 10 kilograms is relatively larger, if able to do after 10 kilograms, will reduce a lot of risk.
