Beschreibung
Inclusion Criteria:
- Age ≥18 years and ≤80 years;
- Diagnosed with pulmonary hypertension (defined as mPAP >20 mmHg measured by right heart catheterization) at least 3 months after successful M-TEER, having received guideline-directed medical therapy (GDMT) for at least 2 months;
- No contraindications for PADN (e.g., anatomical abnormalities of the main pulmonary artery precluding catheter placement, known pulmonary artery stenosis, uncontrolled severe arrhythmias);
- Understands and is willing to sign the informed consent form and authorizes the use of health and study-related information;
- Willing to comply with the treatment and follow-up schedule required by the protocol
Exclusion Criteria:

- Severe renal insufficiency (creatinine clearance rate (CrCL) < 30 mL/min);
- Left ventricular ejection fraction (EF) <30% on echocardiography;
- Severe hematological disease or severe bleeding tendency (platelet count <10×10⁹/L; severe and extensive bleeding; suspected or confirmed intracranial hemorrhage);
- Systemic inflammatory disease, malignancy, tricuspid valve stenosis, pulmonary artery stenosis, and other cardiac diseases requiring surgical or interventional treatment;
- Acute systemic infectious disease;
- Poor general condition due to various systemic diseases;
- Pulmonary veno-occlusive disease;
- Cachexia;
- Diagnosed with WHO Group 1, 3, 4, or 5 pulmonary hypertension;
- Anticipated to undergo other surgical or interventional procedures within 6 months;
- Life expectancy <12 months;
- Allergy to the drugs or metal materials used in the study;
- Women who are breastfeeding, pregnant, or planning to become pregnant within one year;
- Participation in another drug or medical device clinical trial within 3 months prior to screening;
