分析影响小儿先心病室缺纠治术的因素，以提高手术成功率。回顾性分析２０８５例小儿先心室缺纠治术，手术死亡４８例，病死率２．３％。手术死亡与患儿的年龄、体重有关。年龄小于６个月，体重低于６ｋｇ者手术病死率为３５．７％和３０．０％，而年龄大于３岁，体重超过１６ｋｇ者手术病死率低于１．０％。先心室缺的手术时间取决于室缺的位置、大小和心内分流量。室缺伴肺动脉高压患儿必须在２岁前手术，对肺动脉瓣下型室缺患儿应早期手术，防止主动脉瓣脱垂导致主动脉瓣关闭不全．术中避免右室切口，保护术后右心室功能和术后肺动脉高压的处理是手术成功的关键。
Analysis of factors affecting children with congenital heart disease in order to improve the success rate of surgery. A retrospective analysis of 2,085 cases of pediatric premature ventricular septal defect surgery, surgical death in 48 cases, the mortality rate of 2.3%. Surgical death and children’s age, weight related. Surgical mortality rates were 35.7% and 30.0% for patients less than 6 months and less than 6 kg, respectively, and less than 1.0% for those older than 3 years and those weighing more than 16 kg. The absence of preeclampsia depends on the location of the ventricular vacillate, the size and the amount of intracardiac shunting. Atrial and pulmonary hypertension in children with surgery must be before the age of 2, the infants with pulmonary valve infantile malnutrition should be early surgery to prevent aortic valve prolapse resulting in aortic regurgitation. Intraoperative avoidance of right ventricular incision, protection of right ventricular function and postoperative pulmonary hypertension treatment is the key to successful operation.
