先天性心脏病是一种常见的先天性畸形,发病率为6‰～8‰。由于先天性心脏病种类繁多,复杂性又不一,且每一种又轻重不同,因而也就决定了治疗时间的不同。原则上讲,疾病比较轻,对生长、发育影响不大,病情短时间内无明显进展的患儿,可不必急于手术。如小的室间隔缺损有自然闭合的倾向。据国内外研究证明,小的室间隔缺损患儿中约有20%患儿可望自然关闭(即自己长好)。若患儿到5～6岁仍未闭合,再考虑手术也为时不晚。对一些病变较重、表现的症状很显著,如经常患呼吸道感染,甚至肺炎,出现心力衰竭,
Congenital heart disease is a common congenital malformations, the incidence of 6 ‰ ~ 8 ‰. Because of the wide range of congenital heart disease, complexity is different, and each one is different in severity, which also determines the difference in treatment time. In principle, the disease is relatively light, little effect on growth and development, and there is no urgent need for urgent operation in children with no obvious progress in a short period of time. Small ventricular septal defects have a natural tendency to close. According to research at home and abroad, about 20% of children with small ventricular septal defect are expected to close naturally (that is, they grow well). If the child is still not closed to 5 to 6 years old, then consider the surgery is not too late. For some lesions heavier, the performance of the symptoms are significant, such as frequent respiratory infections, and even pneumonia, heart failure,
