Eligibility Criteria

Age22 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Heart Failure with EF ≥ 40% (by TTE within last 3 months)
  • Mean Pulmonary Artery Pressure (mPAP) \>20 mmHg at rest
  • Pulmonary Vascular Resistance (PVR) ≥ 3WU at rest
  • Pulmonary Capillary Wedge Pressure \> 15 mmHg (at rest) or \> 18 with passive leg raise
  • Cardiac index (CI) ≥ 1.7 L/min/m2
  • NYHA Class II or III
  • Glomerular Filtration Rate (GFR) ≥ 25 ml/min
  • Stable, guideline directed medical treatment, including controlled volume status for a minimum of 3 months prior treatment

You may not qualify if:

  • Ambulatory with a Life expectancy of \< 1 years
  • Inability to take dual antiplatelet or anticoagulants, hypersensitivity or allergy to aspirin or clopidogrel
  • Unable to tolerate right heart catheterization
  • Pulmonary artery aneurysm, moderate or greater PA stenosis or other PA anatomy that would prevent safe or proper use of the study device
  • Severe aortic, mitral or pulmonary valve regurgitation
  • Tricuspid regurgitation in conjunction with the presence of cirrhosis or congestive hepatopathy
  • Clot or Thrombus in any potential target ablation zone (right, left or main pulmonary artery)
