Abstract

BACKGROUND: Congenital heart anomalies (CHAs) remain a significant global health burden despite advances in diagnosis and management. Data on CHA burden in North Africa and the Middle East region are scarce. This study aimed to estimate CHA trends from 1990 to 2021. METHODS AND RESULTS: Using the Global Burden of Disease Research 2021 database, we assessed CHA incidence, prevalence, mortality, and disability-adjusted life years (DALYs), stratified by age, sex, and sociodemographic index (SDI) at regional and national levels. Decomposition analysis was used to evaluate the impact of population growth on CHA incidence. In 2021, CHAs caused 35 272 deaths (95% uncertainty interval [UI], 28 067-43 670) and 3 181 543 DALYs (95% UI, 2 544 864-3 899 408) in the North Africa and the Middle East region. Incidence and prevalence increased by 13% (95% CI, 10-17) and 70% (95% CI, 67-74), respectively, whereas CHA-related deaths and DALYs declined by 63% (95% CI, 28-73). Infants <12 months of age accounted for 74.9% of deaths and DALYs, with half occurring within the first month. High-SDI countries had the lowest CHA-related DALYs, whereas middle-SDI countries showed the most substantial decline in mortality. Decomposition analysis highlighted that the actual CHA incidence is lower than expected despite population growth. CONCLUSIONS: Although CHA incidence and prevalence increased, mortality and DALYs decreased, particularly in middle-SDI countries. The highest burden was among infants, with better outcomes in higher-SDI nations. More effective strategies are needed to reduce the preventable childhood deaths related to CHAs in the North Africa and the Middle East region.
