Management of pregnancy in women with palliated and unpalliated congenital heart defects.

Medical advancements have made it possible for more women with congenital heart defects (CHDs) to carry successful pregnancies. Most CHD surgeries or interventions are palliative with persistent residua and sequelae exacerbated by the physiologic stresses of pregnancy. Preconception assessment, a tailored multidisciplinary approach during pregnancy, and a planned, elective delivery followed by careful postpartum monitoring may improve outcomes. Teratogenic medications should be stopped and changed to safer alternatives. Major hemodynamic changes in pregnancy, labor, and delivery may aggravate the underlying cardiovascular defects. Interventions or surgeries, when anticipated, should be performed before pregnancy. Antibiotic prophylaxis is indicated for nearly all palliated and unpalliated defects.
