About

This early feasibility study is intended to characterize the impact of pulmonary artery denervation on the quality of life in Heart Failure Patients with Group 2 Pulmonary Hypertension

Full description

Gradient has developed a novel system for pulmonary artery denervation (PADN) to treat patients with heart failure who also developed pulmonary hypertension (PH). Pulmonary hypertension is frequently associated with left heart failure and is a strong independent predictor of clinical worsening and higher mortality. No therapeutic options are available to treat PH in this selected group of patients with heart failure. The objective is to improve exercise capacity and quality of life by targeting PH in these patients.
