About this trial

It's a phase III, prospective, multicenter, randomized controlled trial to evaluate the safety and efficacy of the pulmonary artery denervation (PADN) for heart failure (HF) patients diagnosed with pulmonary hypertension associate with left heart disease (PH-LHD) by right heart catheterization.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age ≥18, ≤75 years old;

Diagnosed with chronic heart failure for at least 3 months, and have received the GDMT pharmacological treatment based on the 2023 ESC Guidelines for Heart Failure for at least 1 month;

Clinically stable defined by

No intravenous diuretics, inotropes or vasodilators for at least 1 month, and

Disqualifiers

Hypertrophic cardiomyopathy with left ventricular outflow tract obstruction or systolic anterior motion; pericardial disease; infiltrative or inflammatory myocardial disease; valvular stenosis of any of the 4 valves, or severe regurgitation of aortic and pulmonary valves, or active endocarditis; or

Symptomatic carotid stenosis, or transient ischemic attack (TIA) or stroke within 30 days prior to randomization; or

Untreated congenital heart disease; or

Have received any revascularization, including coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) within 6 months prior to randomization; or anticipated to undergo coronary revascularization (CABG or PCI) within 6 months; or

Treatments tested in this trial

  • Pulmonary arterial denervation

    Procedure/Surgery

    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.

  • Guideline-directed medical therapy (GDMT) for heart failure

    Drug

    GDMT medication recommendation including: * Angiotensin-converting enzyme inhibitor (ACEI) or angiotensin-receptor blocker (ARB) or angiotensin receptor-neprilysin inhibitor (ARNI) * Beta-receptor blocker (BB) * Mineralocorticoid receptor antagonist (MRA) * Sodium-glucose co-transporter 2 (SGLT2) inhibitor * Diuretics The medication regimen (type and dosage) will be the investigator's discretion in accordance with the 2023 ESC Guidelines for Heart Failure. The type and dosage of all GDMT medications (except for diuretics) should remain unchanged through follow-up duration (at 12-month visit), unless the participant's conditions need adjust of GDMT regimens. Dosage and single or combination of diuretics are all left at physician's discretion.
