What Is Cardio-Obstetrics?
Cardio-obstetrics is a specialized field at the intersection of cardiovascular medicine and obstetric care. A cardio-obstetrics specialist provides comprehensive cardiac evaluation and management for women with heart disease who are pregnant, planning pregnancy, or in the postpartum period. The field has grown substantially over the past decade as cardiovascular disease has become the leading cause of maternal mortality in the United States, surpassing hemorrhage and infection. Both acquired conditions (cardiomyopathy, valvular disease, arrhythmias) and congenital heart defects contribute to this burden, and both require expert cardio-obstetric management to reduce maternal and fetal risk.
WHO Cardiac Risk Classification in Pregnancy
The modified World Health Organization (mWHO) classification system is the standard framework used to stratify cardiac risk in pregnancy. It assigns pregnant women with heart disease to one of five risk categories (I through IV) based on their underlying diagnosis, current cardiac function, and clinical status. Women in mWHO class I or II generally tolerate pregnancy well with appropriate monitoring. Those in class III face significant maternal risk and require multidisciplinary care in a specialized center. Class IV conditions — including severe pulmonary hypertension, Eisenmenger syndrome, advanced systolic dysfunction, and severe symptomatic obstructive lesions — carry a very high risk of maternal mortality and are considered contraindications to pregnancy. mWHO risk stratification is a core component of our preconception counseling for every woman with heart disease.

Preconception Counseling and Pregnancy Co-Management
The most effective cardio-obstetric intervention happens before conception. Preconception counseling allows your cardiologist to optimize your cardiac status, review medication safety in pregnancy, discuss genetic risk of passing a congenital defect to your baby, plan fetal echocardiographic surveillance, identify conditions that should be treated before pregnancy, and develop a collaborative care plan with your OB and maternal-fetal medicine team. During pregnancy, regular cardiology co-management visits by secure telemedicine ensure that your cardiac status is monitored appropriately and that new symptoms are evaluated without delay.
