What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

    PADN: Contrast pulmonary artery (PA) angiography will be performed to localize the pulmonary artery bifurcation level and calculate the PA diameter. Once the anatomy deemed acceptable, the radiofrequency ablation catheter will be introduced into ostium of the left PA and the distal bifurcation area of the main PA. The catheter will be manoeuvred within the PA to allow energy delivery in a circumferential manner to ensure that the electrodes are tightly in contact with the endovascular surface. About three ablations at 45-55 # for 120 seconds each will be performed in ostium of the left PA and the distal bifurcation area of the main PA. For non-atrial fibrillation patients, dual antiplatelet therapy for 1 month after PADN is recommended. Patients with atrial fibrillation should continue new oral anticoagulants and patients who underwent metal valve replacement should continued oral warfarin anticoagulation according to guidelines, which could determined by the physician.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Clinical worsening

    Clinical worsening events defined as any of the following during the study period:

    1. PAH-related rehospitalization.
    2. Addition of PAH-targeted therapies (increased types/dose of PAH-targeted drugs or diuretics).
    3. ≥10% or ≥30-meter reduction in 6-Minute Walk Distance (6MWD) from baseline.
    4. Atrial septostomy.
    5. Need for lung transplantation.
    6. Cardiovascular death.

    Measured: 1 year

Secondary outcomes (11)
  1. WHO Functional Class changes from baseline

    Measured: 6 months, 1, 2, 3, and 5 years

  2. NT-proBNP/BNP levels from baseline

    Measured: 6 months, 1, 2, 3, and 5 years

  3. 6MWD changes from baseline

    Measured: 6 months, 1, 2, 3, and 5 years

  4. Incidence of pulmonary infections

    Measured: Through study completion, an average of 5 years

  5. All-cause death

    Measured: Through study completion, an average of 5 years

  6. Echocardiographic changes from baseline

    Right atrial diameter (RAD)

    Measured: 6 months, 1, 2, 3, and 5 years

  7. Echocardiographic changes from baseline

    Right ventricular end-diastolic diameter (RVDd)

    Measured: 6 months, 1, 2, 3, and 5 years

  8. Echocardiographic changes from baseline

    Tricuspid annular plane systolic excursion (TAPSE)

    Measured: 6 months, 1, 2, 3, and 5 years

  9. Echocardiographic changes from baseline

    Left ventricular ejection fraction (LVEF)

    Measured: 6 months, 1, 2, 3, and 5 years

  10. Echocardiographic changes from baseline

    Left atrial diameter (LAD)

    Measured: 6 months, 1, 2, 3, and 5 years

  11. Echocardiographic changes from baseline

    Left ventricular end-diastolic diameter (LVDd)

    Measured: 6 months, 1, 2, 3, and 5 years

Questions about this trial

What is this clinical trial studying?

An observational study of Pulmonary Hypertension and Hypertension, Pulmonary Arterial, run by Pulnovo Medical (Wuxi) Co., Ltd. at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 26 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical worsening (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jun 2025.
