Detailed 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.

Notice

Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
