TReatment of Pulmonary Hypertension Group II Study
- Conditions
- Pulmonary Hypertension (PH) Due to Left Heart Disease
- Registration Number
- NCT03611270
- Lead Sponsor
- SoniVie Inc.
- Brief Summary
The objective of this study is to assess the safety and initial effectiveness of the TIVUS™ System when used for pulmonary artery denervation in group II PH patients through change in clinical parameters including hemodynamics, exercise tolerance, and quality of life.
This is a prospective, multi-center, non-randomized, open-label clinical trail. The study will be conducted in up to 3 centers and will recruit up to 15 patients diagnosed with pulmonary hypertension due to left heart disease that demonstrate combined pre and post capillary involvement with PVR\>3 wood units.
