Sécurité et efficacité de l'angioplastie pulmonaire par ballonnet en Chine
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.

Description détaillée
This study is a prospective, multi-center, long-term observational project to study the safety and efficacy of BPA. Clinical evaluation, including: functional capacity, 6-minutes walking test, biomarkers, cardiopulmonary exercise test, electrocardiography, echocardiography, haemodynamics, pulmonary angiography and lung scintigraphy was performed before the initiation therapy of BPA, and 3-12 months after last session of BPA.
we also aim to evaluate the value of FAPI in predicting the efficacy and the prognosis of patients with CTEPH who received BPA.
