A subnormal birth weight distribution was noted in a population of infants seen during the first year of life for major congenital heart disease (CHD). When arranged according to cardiac diagnostic categories, 17 of the 21 major cardiac lesions were associated with subnormal birth weight distribution. Major extracardiac anomalies present in 19.9% of all infants appeared not to influence the birth weight distributions of either the total population of 19 of 21 cardiac lesion categories. An increased incidence (6.1%) of small-for-dates infants was observed in the study population. Extra-cardiac anomalies occurred in 28% of the small-for-dates infants. Survival to 1 year of age was 42.8% for the total population with CHD and 49.2% in the small-for-dates group.
在第一年因患重大先天性心脏病（CHD）接受检查的婴儿群体中，发现出生体重分布低于正常水平。按照心脏诊断类别进行排列时，21种主要心脏病变中有17种与出生体重分布低于正常水平相关。所有婴儿中19.9%存在的主要心脏外异常似乎并未影响21种心脏病变类别中19种的总体出生体重分布。在研究人群中观察到小样儿的发病率有所增加（6.1%）。28%的小样儿出现了心脏外异常。CHD总体人群1岁时的生存率为42.8%，小样儿组为49.2%。
