Pregnancy and contraception in young women with congenital heart disease: General considerations.

Young women with heart disease are increasingly being seen in obstetrical referral centres owing, in large part, to the dramatic improvements in survival of young adults with congenital heart disease in recent years. Although pregnancies in most women with heart disease result in favourable outcomes, there are important exceptions that must be recognized. These exceptions pose significant mortality risk to the mother and/or the fetus. The present article outlines cardiovascular adaptations to pregnancy, general outcomes and management considerations for practitioners caring for pregnant young women with congenital heart disease. A lesion-specific review is published in a complementary article.
