Safety and Efficacy of Balloon Pulmonary Angioplasty in China

December 14, 2023 updated by: Chinese Pulmonary Vascular Disease Research Group

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.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed 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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Accepts Healthy Volunteers

No
