Background:
Primary pulmonary hypertension is a rare and dangerous entity in pregnancy. Previous studies have found a 35-50% maternal mortality rate in the peripartum period. To date, most reports have described treatment of these patients with diuretics, digoxin, and calcium-channel blockers.
Case:
We describe the successful treatment of a primigravida with severe primary pulmonary hypertension. We used elective intubation before labor, inhaled nitric oxide therapy, and assisted vaginal delivery with epidural anesthesia that resulted in a viable infant and survival of the mother.
Conclusion:
Nitric oxide can be used to successfully treat primary pulmonary hypertension in pregnancy.

Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
