What this study is about

In the sponsor’s own words, from the registry.

Balloon pulmonary angioplasty (BPA) is a potential treatment for patients with pulmonary artery stenosis, including non-operable patients with chronic thromboembolic pulmonary hypertension (CTEPH), takayasu arteritis and fibrosis mediastinitis.

The aim of this study was to evaluate the safety and efficacy of BPA in CTEPH and patients not amenable to pulmonary endarterectomy(PEA) or suffered from persistent CTEPH after PEA, , takayasu arteritis and fibrosis mediastinitis.
