Congenital heart disease (CHD) is present in 0.8-0.9% of live births. Prevalence of CHD is constantly increasing during the last decades in line with the treatment options for patients ranging from the surgical as well to the interventional spectrum. Most of the women with underlying CHD reach adulthood due to excellent surgical and interventional treatment options and most of them desire pregnancy. In Western countries, maternal heart disease is the major cause of mortality during pregnancy, thus risk estimation should be therefore individualized depending on the underlying CHD, functional class and treatment options. Pre-pregnancy counselling is mandatory in all women, especially in patients with high risk but even in patients with low risk, a plan for labor and delivery should be outlined in a heart pregnancy team. This review addresses the key element of pre-counselling, planning and successful disease management in patients with CHD during pregnancy.
