Prospective validation and assessment of cardiovascular and offspring risk models for pregnant women with congenital heart disease.

Objectives: Adequate prepregnancy prediction of maternal cardiovascular and offspring risk is important for counselling and management of pregnancy in women with congenital heart disease (CHD). Therefore we performed a study to identify the optimal assessment strategy for estimating the risk of pregnancy in women with CHD.

Methods: In this prospective study, we determined the outcomes of 213 pregnancies in 203 women with CHD.
