About this trial

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.

This trial does not accept healthy volunteers

Qualifiers

diagnosed with CTEPH according to ESC Guidelines (1) Mean PAP ≥ 25mmHg at rest; or if mean PAP < 25mmHg at rest, have exercise limitations from chronic thromboembolic disease (2)Abnormal ventilation perfusion lung scanning (VQ) scan, pulmonary angiogram, computer tomographic pulmonary angiogram, or magnetic resonance pulmonary angiogram confirming chronic thromboembolic disease as recommended by standard guidelines

Treatment with anticoagulation for ≥ 3 months before diagnosis of CTEPH

Not amenable to pulmonary endarterectomy

Willing to provide informed consent

Disqualifiers

Patients unwilling or unable to provide written consent for participation in the study.

Impossible to follow up.

Trial population

Treatments tested in this trial

  • Balloon pulmonary angioplasty

    Procedure/Surgery

    Balloon pulmonary angioplasty is an interventional technique where a balloon catheter is used to recanalize affected segments of pulmonary arteries identified during angiography.

Trial outcomes

Primary outcomes

1

Incidence of Treatment-Emergent Adverse Events of BPA procedure.

Surveillance of complications including: vessel injury, desaturation, cough, mild hemoptysis (\<50ml), severe hemoptysis (\>50ml), reperfusion pulmonary injury, death.

Time frame
From initiation of BPA to 3-12 months after last session
2

Change of Pulmonary artery pressure in mmHg caused by series of BPA.

Pulmonary artery pressure in mmHg is obtained by right cardiac catheterization.

Time frame
From initiation of BPA to 3-12 months after last session
3

Change of Pulmonary vascular resistance (PVR) in Wood U caused by series of BPA.

Pulmonary vascular resistance (PVR) in Wood U is obtained by right cardiac catheterization.

Time frame
From initiation of BPA to 3-12 months after last session
4

Change of cardiac index (CI) in L/m^2 caused by series of BPA.

Cardiac index (CI) in L/m\^2 is obtained by right cardiac catheterization.

Time frame
From initiation of BPA to 3-12 months after last session
