Vaginal delivery in a patient of Eisenmenger syndrome.

Eisenmenger syndrome consists of a congenital communication between the systemic and pulmonary circulation, with resultant pulmonary arterial hypertension and reversal of flow through the defect. Pregnancy in the setting of pulmonary hypertension and Eisenmenger physiology is associated with a substantial maternal and fetal risk. It is usually associated with high mortality rates (30-50%). Pregnancy in such patients is contraindicated. Patients with Eisenmenger's syndrome in pregnancy often deliver prematurely. Oxygen, anti-coagulants, and vasodilators are mainstay of treatment.
