title: Pulmonary hypertension due to fibrosing mediastinitis treated successfully with stenting of pulmonary vein stenoses.
abstract: We describe a patient with fibrosing mediastinitis after childhood histoplasmosis who presented with severe pulmonary hypertension secondary to pulmonary vein stenoses. Stenting of 2 stenosed pulmonary veins via a transseptal approach resulted in an immediate decrease in systolic pulmonary artery pressure from 90 to 68 mm Hg and improvement in dyspnea and cardiac index, which was sustained at 6 months. This case highlights the importance of routinely assessing the pulmonary veins during workup for pulmonary hypertension.
