Pregnancy outcome in patients with pulmonary arterial hypertension receiving prostacyclin therapy.

Background: Pregnancy is contraindicated in cases of pulmonary hypertension, a highly morbid disease affecting young women of childbearing age.

Cases: We describe the pregnancies of 3 patients with pulmonary arterial hypertension (idiopathic, Eisenmenger syndrome, and related to systemic lupus erythematosus). They received epoprostenol and low-molecular-weight heparin throughout pregnancy. The patient with Eisenmenger syndrome started epoprostenol in gestational week 16. Cesarean delivery under general anesthesia was performed at 28-33 weeks of gestation; early delivery was necessary in the patient with Eisenmenger syndrome because of fetal growth restriction. All deliveries were uneventful, and birth weights were 1,700, 1,500, and 795 g. There were no postpartum complications.

Conclusion: Pregnancy in women with pulmonary hypertension should still be considered high risk for both mother and child, but stable patients on epoprostenol may successfully complete pregnancy.
