Objective:To analyze global disparities in research on the neurodevelopment and neuropsychology of congenital heart disease (CHD) in the past 20 years (2000-2019) and explore the association with its disability burden.Method: A bibliometric analysis of articles published between 2000 and 2019 in SCOPUS.Country-level data on disability-adjusted life years (DALYs per 100,000 persons) for CHD was obtained from the Global Burden of Disease Study-2019, and income group was obtained from the World Bank database.Results: The research output rate was 1.81 articles per million in high-income countries (HICs) and 0.07 in low-and middle-income countries (LMICs).Research output was 27 times higher in HICs than in LMICs (p < 0.001).In LMICs, the DALY rate was 5.2 (95% CI: 4.9-5.5)times higher than in HICs.We found a negative association between research productivity and the DALY rate (RR = 0.9; 95% CI: 0.8-0.9).Conclusion: We found similar disparity patterns
