This study is a prospective, non-randomized, two arm, single-center acute feasibility study assessing safety and performance of the Aria CV Acute PH System in WHO Group 2 and 3 PH patients.
This study is a prospective, non-randomized, two arm, single-center acute feasibility study assessing safety and performance of the Aria CV Acute PH System in WHO Group 2 and 3 PH patients.
The planned enrollment is a maximum enrollment of 40 patients to ensure up to 10 "Device Deployed" subjects in each arm at one site.
The duration of study participation for each subject is expected to be approximately 60 days.
The Aria CV Acute PH System is indicated for evaluation of hemodynamic responses (e.g. pulmonary arterial compliance, cardiac output, and effective arterial elastance) to an intravascular Balloon catheter temporarily placed in the pulmonary artery in symptomatic adult patients with WHO Group 2 or WHO Group 3 pulmonary hypertension and right ventricular dysfunction.
