A Trial to Evaluate the Safety and Efficacy of Pulmonary Artery Denervation for the Treatment of Pulmonary Hypertension Associated With Left Heart Failure

Inclusion Criteria: 1. Age ≥18, ≤75 years old; 2. 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; 3. Clinically stable defined by 1. No intravenous diuretics, inotropes or vasodilators for at least 1 month, and 2. Systolic blood pressure (SBP) ≥ 100 and \< 160 mmHg and resting heart rate (HR) ≥50 and \<100 bpm (\<110 bpm for atrial fibrillation) on the day of the procedure 4. New York Heart Association (NYHA) class II-IVa; 5. 6MWD ≥ 100 m and \< 450 m; 6. NT-proBNP \> 125 pg/mL (BNP \> 35 pg/mL); 7. Hemodynamic indicators (RHC) : 1. Mean pulmonary arterial pressure (mPAP) \> 20 mmHg 2. Pulmonary capillary wedge pressure (PCWP) \>15 mmHg 8. Understand and be willing to sign informed consent, and be willing to follow the follow-up plan required by the protocol. Exclusion Criteria: 1. Any of the following: 1. 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 2. Symptomatic carotid stenosis, or transient ischemic attack (TIA) or stroke within 30 days prior to randomization; or 3. Untreated congenital heart disease; or 4. 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 5. Artificial pacemakers, including single-chamber, dual-chamber and three-chamber pacemakers, have been implanted or are anticipated to be implanted within 6 months; or 6. Anticipated to undergo ablation of atrial fibrillation within 6 months; or 7. Anticipated to undergo heart valve surgery (valve replacement, valvuloplasty) within 6 months; or 8. Listing for heart/heart-lung transplantation or anticipated to implant a ventricular assist device (VAD) 2. Other types of pulmonary hypertension, including WHO Group1, Group3, Group4, Group5; 3. Received pulmonary arterial hypertension (PAH) targeted drugs within 1 month prior to randomization; 4. Anticipated to undergo any surgery within 6 months; 5.
