Labor Onset and Delivery Mode in Women With Congenital Heart Disease—A Nationwide Cohort Study

( Acta Obstet Gynecol Scand . 2025;104:666–675. doi: 10.1111/aogs.15064.) Over the past few decades, more women with congenital heart disease (CHD) have reached child-bearing age and become pregnant, raising concerns about how their heart condition may influence labor and delivery. This study used statistical models to explore the differences in labor onset and delivery methods between women with and without CHD, as well as to analyze how these trends have changed over time. Using data from a nationwide Norwegian cohort spanning from January 1, 1994 to December 31, 2014, researchers examined childbirths categorized by the severity of maternal CHD (classified as mild, moderate/severe, or other CHD) compared with childbirths in women without any heart disease.
