Labor onset and delivery mode in women with congenital heart disease-A nationwide cohort study.

ABSTRACT:

Introduction

More women with congenital heart disease (CHD) are pursuing pregnancy. Their cardiac condition may impact the pregnancy and necessitate interventions during childbirth. We aimed to investigate labor onset and delivery mode in women with CHD relative to women without heart disease and explore the time trends of induced labor and cesarean deliveries.

Material and methods

In a nationwide cohort in Norway from 1994 to 2014, we compared childbirths of women with mild, moderate/severe, or other CHD to childbirths of women without heart disease. Associations between maternal CHD and labor onset and delivery mode were estimated using log-binomial regression. Time trends were assessed using Joinpoint regression.

Results

Among 1 218 452 childbirths, 2425 (20 per 10
