Abstract

Background: To determine the prevalence and pattern of congenital heart disease (CHD) among elementary school children in Dongguan, China.

Methods: Between November 2011 and November 2012, 540,574 school children from 449 elementary schools were screened for CHD by trained doctors in Dongguan. The school children who were suspected to have CHD were referred to a pediatric cardiologist and/or an echocardiographer for a complete evaluation.

Results: The total prevalence of CHD was 2.14 per 1,000 school children (1,157/540,574). The most common form of CHD was isolated ventricular septal defect (37.77%; 437/1,157), followed by isolated atrial septal defect (20.22%; 234/1,157) and patent ductus arteriosus (9.94%; 115/1,157). With respect to sex, CHD was equally distributed between males and females.

Conclusion: Our data show that the prevalence of CHD in Dongguan is not as high as expected and that isolated ventricular septal defect is the predominant pathology. Echocardiography plays a crucial role in the diagnosis of CHD.

中国东莞学龄儿童先天性心脏病的患病率和模式。

背景：目的：了解中国东莞市小学生先天性心脏病（CHD）的患病率和发病模式：调查中国东莞市小学生先天性心脏病（CHD）的患病率和模式：方法：2011 年 11 月至 2012 年 11 月期间，东莞市经过培训的医生对 449 所小学的 540,574 名学龄儿童进行了先天性心脏病筛查。疑似患有先天性心脏病的学龄儿童将被转诊至儿科心脏病专家和/或超声心动图专家处进行全面评估：结果：每 1,000 名学龄儿童中有 2.14 人患有先天性心脏病（1,157/540,574）。最常见的先天性心脏病是孤立性室间隔缺损（37.77%；437/1,157），其次是孤立性房间隔缺损（20.22%；234/1,157）和动脉导管未闭（9.94%；115/1,157）。在性别方面，CHD 在男性和女性之间的分布相当：我们的数据显示，东莞的先天性心脏病发病率并不像预期的那么高，孤立性室间隔缺损是主要的病因。超声心动图在诊断先天性心脏病中起着至关重要的作用。
