Condition(s) studied

Pulmonary Hypertension

Investigational drug(s) / intervention(s)

Gradient Denervation System

Gradient Denervation System: The Gradient Denervation System delivers ultrasound ablation to planned locations in the pulmonary artery to down-regulate the sympathetic nervous drive. The system includes a sterile, single-use catheter that is designed to centrally position the transducer within the arterial target zone for consistency of ablation.

Study summary

Characterize the impact of pulmonary artery denervation on the quality of life in Heart Failure Patients with Group 2 Pulmonary Hypertension
