Overview
Approximately 1-4% of pregnancies in the United States occur in women with maternal cardiovascular disease. In fact, pregnancy can "unmask" underlying cardiovascular disease, due to the hemodynamic changes associated with pregnancy. [1] With a careful pre-pregnancy evaluation, most women with cardiovascular disease can carry a pregnancy to term with proper care.
Epidemiology and Demographics
Increasing numbers of women with congenital heart disease are now reaching childbearing age, making congenital heart disease the most common form of heart disease complicating pregnancy in the United States. Rheumatic heart disease is still prevalent in the developing world and in immigrant populations. Overall, maternal death during pregnancy in women with heart disease is rare, but certain conditions are associated with an increased mortality.[2]
Disorders Associated with Cardiovascular Disease in Pregnancy
Maternal cardiovascular disease includes (most commonly) congenital heart disease. Other cardiovascular disorders encountered during pregnancy include cardiomyopathies, both dilated and hypertrophic, and valvular heart disease, such as bicuspid aortic valve and mitral valve prolapse. Less common cardiovascular disorders include pulmonary hypertension and, rarely, coronary artery disease. The above cardiovascular disorders require a strategy regarding the frequency of follow-up by the cardiologist and a plan for labor and delivery.[3]
Risk Factors
The following clinical characteristics are independent predictors in a risk score for maternal cardiac complications[4]:
- Prior cardiac events or arrhythmia
- Poor functional class or cyanosis
- Left ventricular outflow obstruction
- Left ventricular systolic dysfunction
