Clinical Trial Summary

The objective of this study is to research the relationship between maternal exposure to environmental factors and fetal congenital heart disease in a community-based case-control study.

Clinical Trial Description

This is a community-based case-control study in SHANGHAI,a municipality in CHINA. Cases will be identified from maternity centers.
