Acquired heart disease in pregnancy

The incidence of rheumatic heart disease in most industrialized countries is decreasing. Those women who have regurgitant lesions will commonly experience an improvement in symptoms, and therapy is required only in the most severe cases. Women with mild to moderate stenotic lesions can usually expect a good outcome to pregnancy, but women with severe stenotic lesions require close monitoring by both their obstetricians and their cardiologists, especially during the third trimester, labour and delivery, and the early postpartum period. This is the third in a series of five articles reviewing in detail the assessment and management of specific cardiac disorders in pregnancy.
