Clinical Trial Summary

Balloon pulmonary angioplasty (BPA) is a potential treatment for non-operable patients with chronic thromboembolic pulmonary hypertension (CTEPH).

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

Description:

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.
