Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
