简要总结
The objective of this study is to assess the safety, performance and initial effectiveness of the TIVUS™ System when used for pulmonary artery denervation through subjective and objective change in clinical parameters and haemodynamic evaluation. This is a prospective, multi-center, non-randomized, open-label clinical trail. The study will be conducted in up to 5 centers and will recruit up to 15 patients diagnosed with PAH, functional class III who have stable PAH on a stable drug regimen of two pulmonary arterial hypertension specific medications.

入选标准
- •Patient with known pulmonary arterial hypertension (PAH), which has been diagnosed as idiopathic PAH, connective tissue disease PAH, anorexigen induced or familial PAH
- •PAH diagnosis confirmed by hemodynamic evaluation performed prior to screening and showing all of the following: Mean pulmonary artery pressure (mPAP) ≥25 mmHg at rest; Pulmonary capillary wedge pressure (PCWP) or left ventricular end diastolic pressure (LVEDP) ≤15 mmHg; Pulmonary vascular resistance (PVR) at rest >3 Wood units; Not meeting the criteria for a positive vasodilator response (fall in mPAP ≥ 10 mmHg to ≤ 40 mmHg).
- •Patient with a current diagnosis of WHO functional class III
- •Patient should be on two pulmonary arterial hypertension specific medications other than parenteral prostanoids
- •Patient is adhering to a stable drug regimen (i.e., with no changes of dose or medication for a minimum of 3 months prior to enrollment)
- •Patient with eGFR levels of ≥ 30 ml/min/1.73m2or serum creatinine levels of ˂ 150µmol/l
排除标准
- •Patient who are treated with parenteral prostanoids
- •Pregnant women or women planning a pregnancy within 12 months of study enrolment
- •Patient with significant co-morbid conditions which, at the discretion of the PI, are deemed to prohibit study entry
- •Patient with life expectancy of less than a year
- •Concurrent enrollment in another device or drug trial except for observational studies (unless specifically approved by the sponsor)
- •Patient with pulmonary artery anatomy that precludes treatment
- •Patient with moderate to severe pulmonary artery stenosis
- •Patient with any pulmonary artery aneurysm
- •Patient who has experienced a myocardial infarction, unstable angina pectoris, or a cerebrovascular accident in the previous 6 months
