•1\. Male or female participants \=1 to \<18 years of age at the time of providing documented informed consent/assent
•2\. Documented, historic diagnostic RHC any time before Screening confirming the diagnosis of PAH WHO Group 1 in any of the following subtypes (for participants with a history of cardiac intervention for shunt closure, the RHC confirmation must have been performed more than 6 months after the cardiac intervention):
•\- Heritable PAH
•\- Drug/toxin\-induced PAH
•\- PAH associated with CTD
•\- PAH\-CHD with shunt closure \>6 months before Screening and subsequently confirmed by RHC before Screening
•\- PAH with coincidental shunt
•3\. For the above\-mentioned historical RHC, diagnostic criteria will be mean pulmonary artery pressure \=20 mmHg at rest, pulmonary capillary wedge pressure or left ventricular end\-diastolic pressure \=15 mmHg, and PVR \>240 dynes•sec•cm\-5
•4\. PAH classified as WHO FC I or symptomatic PAH classified as WHO FC II to IV
•5\. Participants must be on a stable dose(s) of background PAH therapy:

•1\. History of left\-sided heart disease, including valvular disease (eg, moderate or greater mitral or aortic regurgitation or stenosis), left ventricular outflow tract obstruction, and/or left heart failure (eg, restrictive or dilated cardiomyopathy)
•2\. Severe (as based on the opinion of the investigator) congenital abnormalities of the lung, thorax, and/or diaphragm
•3\. History of Eisenmenger syndrome
•4\. Unrepaired or residual cardiac shunt with Qp/Qs \>1\.5
•5\. Diagnosis of pulmonary veno\-occlusive diseases, pulmonary capillary hemangiomatosis, or overt signs of capillary and/or venous involvement
•6\. PAH associated with portal hypertension
•7\. Known visceral (lung, liver, or brain) arteriovenous malformation(s)
•8\. History of full or partial pneumonectomy
•9\. Untreated more than mild obstructive sleep apnea
•10\. History of known pericardial constriction
