Eligibility Criteria
Inclusion Criteria: Written informed consent obtained from subject > 18 years of age Diagnosis of NYHA Class III Heart Failure with preserved ejection fraction defined as LVEF≥45% At least 1 heart failure related hospitalization or urgent outpatient visit within 12 months of baseline visit Presence of pulmonary hypertension defined as mPAP>25 mmHg at rest or mPAP/CO slope >3 mmHg/L/min during exercise during right heart catheterization or tricuspid regurgitation velocity of > 2.8 m/s assessed by transthoracic echocardiography (data must be taken within the last 6 months prior to implantation) Subjects with a BMI ≤ 35. Subjects with BMI >35 will require their chest circumference to be measured at the axillary level, if > 65 inches the patient will not be eligible for the study. Subjects with pulmonary artery branch diameter ≥ 7mm - (implant target artery - assessed during the RHC) Subjects willing and able to comply with the follow-up requirements of the study All participants need to be able to perform at least 40 watts on an upright bicycle stress test. Exclusion Criteria: Subjects with an active infection Subjects with history of recurrent (> 1) pulmonary embolism or deep vein thrombosis Subjects who, in the Investigator's opinion, are unable to tolerate a right heart catheterization Subjects who have had a major cardiovascular event (e.g., myocardial infarction, open heart surgery, stroke, etc.) within 2 months of Baseline Visit Subjects with Cardiac Resynchronization Device (CRT) , pacemaker or Implantable Cardioverter Defibrillator (ICD) Subjects with a Glomerular Filtration Rate (GFR) < 25 ml/min (obtained within 2 weeks of the baseline visit) who are non-responsive to diuretic therapy or who are on chronic renal dialysis Subjects with congenital heart disease or mechanical heart valve(s) Subjects likely to undergo heart transplantation or VAD within 6 months of baseline visit Subjects with known coagulation disorders Subjects with a hypersensitivity or allergy to aspirin, and/or clopidogrel (not applicable for subjects taking anti-coagulation therapy or other approved anti-platelets therapy).
