Canadian Cardiovascular Society: Clinical Practice Update on Cardiovascular Management of the Pregnant Patient

The number of women of childbearing age with cardiovascular disease (CVD) is growing because of increased survival of children with congenital heart disease. More women are also becoming pregnant at an older age, which is associated with increased rates of comorbidities including hypertension, diabetes, and acquired CVD. Over the past decade the field of cardio-obstetrics has significantly advanced with the development of multidisciplinary cardio-obstetric programs (COPs) to address the increasing burden of CVD in pregnancy. With the introduction of formal COPs, pregnancy outcomes in women with heart disease have improved. COPs provide preconception counselling, antenatal and postpartum cardiac surveillance, and labor and delivery planning. Prepregnancy counselling in a COP should be offered to women with suspected CVD who are of childbearing age. In women who present while pregnant, counselling should be performed in a COP as early as possible in pregnancy. The purpose of counselling is to reduce the risk of pregnancy to the mother and fetus whenever possible. This is done through accurate maternal and fetal risk stratification, optimizing cardiac lesions, reviewing safety of medications in pregnancy, and making a detailed plan for the pregnancy, labor, and delivery. This Clinical Practice Update highlights the COP approach to prepregnancy counselling, risk stratification, and management of commonly encountered cardiac conditions through pregnancy. We highlight "red flags" that should trigger a more timely assessment in a COP. We also describe the approach to some of the cardiac emergencies that the care provider might encounter in a pregnant woman.
