Subjects will have Optical coherence tomography (OCT) and Intravascular Ultrasound (IVUS) imaging during the right heart catheterization that diagnoses them as having PAH. Subjects will start their bosentan and will be followed by monthly clinic visits for 4 months. At 4 months they will have repeat OCT and IVUS imaging.
