The objectives of the RELIEVE-PAH study are to obtain first-in-human experience with the study device in patients with severe pulmonary arterial hypertension, including evidence of initial safety, device performance and possible signals of clinical effectiveness.


This is a multi-national, multi-center, prospective, non-randomized, open label trial of patients implanted with the study device. A total of up to 20 patients will be implanted with the study device and followed at regular intervals for 1 year and then annually for a total of 5 years post implant.

Inclusion Criteria

Group 1 PAH (idiopathic, connective tissue disease, HIV, corrected congenital heart disease)
WHO Functional Class III or IV symptoms. If WHO Class III, at least 1 High-Risk characteristic or 2 Intermediate-Risk characteristics from the 2015 ESC Guidelines
Receiving maximal available and tolerable pharmacological PAH therapy 3 months at a stable dose for 1 month

Exclusion Criteria

Resting oxygen saturation <90 % without supplemental oxygen corrected for altitude
Mean Right Atrial Pressure >20 mmHg
Severe restrictive or obstructive lung disease
Evidence of organ dysfunction other than right heart failure
Left ventricular ejection fraction <40 %
Anatomical anomaly on transesophageal echocardiography or intracardiac echocardiography that precludes implantation of Shunt across fossa ovalis (FO) of the interatrial septum
Inadequate vascular access for implantation of shunt, e.g. femoral venous access for transseptal catheterization and inferior vena cava (IVC) is not patent
Hemodynamic heart rhythm, or respiratory instability at time of Final Exclusion Criteria
Clear my responses
