Trend in delivery hospitalizations among women with congenital heart disease per 10,000. There was a significant linear increase in the delivery hospitalizations of women with congenital heart disease from 6.4 (95% confidence interval [CI] 6.2–6.7) per 10,000 delivery hospitalizations in 2000 to 9.0 (95% CI 8.7–9.3) per 10,000 delivery hospitalizations in 2010 (R2=0.91, P<.001). Error bars at each point estimate are 95% CIs.
