Summary

Prolonged pulmonary venous congestion culminates in pulmonary hypertension, defined as a mean pulmonary arterial pressure \> 20 mmHg and pulmonary artery wedge pressure \>15 mmHg at rest, as determined by right heart catheterization. Pulmonary hypertension secondary to heart failure (PH-HF) is further stratified into isolated post-capillary pulmonary hypertension (Ipc-PH, pulmonary vascular resistance (PVR) is ≤2 Woods Unit) and combined pre- and post-capillary pulmonary hypertension (Cpc-PH, PVR \> 2 Woods Unit), the later reflecting additional pulmonary vascular constriction or remodeling in addition to passive PH. While medications tailored for World Health Organization defined Group I pulmonary arterial hypertension are not endorsed for PH-HF according to current guidelines, the coexistence of pulmonary hypertension exacerbates the severity of heart failure. Given the presence of pulmonary arterial vasoconstrictor and heightened sympathetic nervous activity in patients with heart failure, the PADN-5 study has demonstrated the safety and efficacy of pulmonary artery denervation (PADN) for patients with CpcPH, characterized by the improvements in left ventricular ejection fraction, cardiac output, clinical outcome, and reductions in left atrial pressure, pulmonary arterial pressure, and PVR. Our objective is to assess the feasibility, safety, and efficacy of PADN for patients with heart failure independent of left ventricular ejection fraction (HFrEF or HFpEF) without pulmonary hypertension (N=30, 15 with HFrEF and another 15 with HFpEF).

DEVICE

Pulmonary artery denervation (PADN)

Combining invasive angiography with pulmonary artery CTA is frequently employed to determine the final size of the PADN catheter, aiming for an expected ratio of distal ring/vessel diameter between 1.1 and 1.2. The PADN system comprises a radiofrequency generator, connecting tubing and control handle, and the PADN catheter. The main interface of the radiofrequency generator offers multiple language options and displays parameters such as temperature, impedance, energy, and ablation time. The generator features three control modes: temperature control, power control, and a combination of both.
