Maternal cardiovascular risk assessments for patients with pulmonary hypertension.

Modified WHO Classification	Class IV: Extremely High–Risk Maternal Mortality and Morbidity (cardiomyopathy with LVEF < 30%, pulmonary hypertension, native severe coarctation, severe mitral and aortic stenosis) = 40–100% risk of maternal cardiovascular complications
CARPREG II Risk Predictors (Weighted risk score based on lesion, imaging parameters, and patient factors)	Pulmonary Hypertension (2) = 10% maternal cardiac complications risk
