A Hospital-Based Study on Congenital Heart Defects — Haidian District, Beijing Municipality, China, 2013–2022

WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Congenital heart defects (CHDs) represent the most prevalent birth defects in China, exhibiting significant mortality and morbidity rates. Recent years have witnessed a steady increase in the occurrence of CHDs, highlighting a crucial need for rigorous research focus. WHAT IS ADDED BY THIS REPORT? The cumulative birth prevalence of CHDs in Haidian District from 2013 to 2022 was 80.77 per 10,000 births, reflective of an upward trend primarily influenced by the diagnosis of minor, non-critical congenital defects (non-CCHDs). This increase can be attributed to advancements in diagnostic methodologies. Despite the progress in detection, the survival rate for CHDs did not correspondingly improve. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? Policies need to be formulated to promote the graded management of CHDs. There should be timely updates to the diagnostic criteria to align with advancements in diagnostic techniques. Moreover, in instances where therapeutic abortion is not required, the provision of appropriate medical consultation post-diagnosis should be enhanced.
