Catheter-based Endovascular Angioplasty for Fibrosing Mediastinitis-associated Pulmonary Vein Stenosis
Published on: August 26, 2025
Abstract:
Pulmonary arterial hypertension is an uncommon but disabling and often fatal condition, in which there is a sustained rise in pulmonary arterial pressure due to progressive obliteration of the pulmonary vascular bed. [symbol: see text] Bosentan (Tracleer-Actelion), which belongs to a new class of drugs called endothelin receptor antagonists, is now available for treating patients with pulmonary arterial hypertension. Here we assess whether bosentan offers worthwhile benefits in the management of patients with this condition.
