Gestational pulmonary arterial hypertension

PVRI Member Authors: Hap Farber

Abstract

Pulmonary arterial hypertension (PAH) is a progressive disease marked by the irreversible pulmonary vascular changes of vasoconstriction, thrombosis, and proliferation of smooth muscle and endothelial cells. The untreated clinical course is characterized by progressive dyspnea and a median survival of less than 3 years. Many of these patients are of child-bearing age; however, pregnancy leads to physiologic changes that are particularly poorly tolerated in PAH, conferring a 30%–56% mortality. We present a case of PAH that spontaneously resolved after termination of pregnancy and recurred during each of two subsequent pregnancies. To our knowledge, this case is unique, because no cases of spontaneous resolution of idiopathic PAH have been reported in adults, nor have there been any reports of pulmonary hypertension that is isolated to the gestational period.
