Brief Summary:
The International Balloon Pulmonary Angioplasty (BPA) Registry is a prospective, multi-center, long-term observational project. Scheduled to start data collection in Q4 2017, the registry will run for approximately four years with a follow-up time for each patient of at least two years. Its primary objective is to investigate the efficacy and safety of BPA intervention in patients with chronic thromboembolic pulmonary hypertension (CTEPH) not amenable to pulmonary endarterectomy (PEA).

Condition or disease Intervention/treatment
Chronic Thromboembolic Pulmonary Hypertension CTEPH Procedure: Balloon pulmonary angioplasty

Intervention Details:
  • Procedure: Balloon pulmonary angioplasty
    BPA is an interventional technique where a balloon catheter is used to recanalize affected segments of pulmonary arteries identified during angiography.
    Other Name: BPA

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Safety as assessed by BPA-associated complications [ Time Frame: Min. 2 years ]
  2. Efficacy as assessed by change in PVR [ Time Frame: Min. 2 years ]
    Change in pulmonary vascular resistance (PVR) from baseline to latest post-interventional follow-up hemodynamics

  3. Efficacy as assessed by change in mPAP [ Time Frame: Min. 2 years ]
    Change in mean pulmonary arterial pressure (mPAP) from baseline to latest post-interventional follow-up hemodynamics


Secondary Outcome Measures :
  1. Compare volume of BPA cases across regions and case load at the end of recruitment [ Time Frame: Min. 2 years ]
  2. Analyze patient selection criteria for BPA across sites at the end of recruitment [ Time Frame: Min. 2 years ]
  3. At the end of follow-up, compare technical aspects of BPA as asssed by imaging modalities as used by the sites [ Time Frame: Min. 2 years ]
    Imaging modalities encompass VQ scan, selective pulmonary angiogram, CT pulmonary angiogram, dual-energy CT, cone-beam CT, MRI, OCT and IVUS

  4. At the end of follow-up, compare technical aspects of BPA as assessed by investigator-reported session goals [ Time Frame: Min. 2 years ]
  5. At the end of follow-up, compare technical aspects of BPA as assessed by number of sessions per patient and follow-up [ Time Frame: Min. 2 years ]
  6. At the end of follow-up, compare technical aspects of BPA as assessed by number of interventions per patient and follow-up [ Time Frame: Min. 2 years ]
  7. At the end of follow-up, compare technical aspects of BPA as assessed by technical limits [ Time Frame: Min. 2 years ]
  8. Analyze the use of PH targeted medical therapy before BPA [ Time Frame: Min. 2 years ]
    PH targeted therapy will be categorised as prostacyclin, IP agonist, PDE5 inhibitor, ERA, guanylate cyclase stimulator and other

  9. Analyze the use of PH targeted medical therapy after BPA [ Time Frame: Min. 2 years ]
    PH targeted therapy will be categorised as prostacyclin, IP agonist, PDE5 inhibitor, ERA, guanylate cyclase stimulator and other

  10. Analyze the impact of PH targeted medical treatment on key patient outcomes [ Time Frame: Min. 2 years ]
    PH targeted therapy will be categorised as prostacyclin, IP agonist, PDE5 inhibitor, ERA, guanylate cyclase stimulator and other Key patient outcomes encompass WHO functional class, 6-minute-walk-distance, Borg dyspnoe score, haemodynamics and mortality

  11. Health care resource use required to complete BPA [ Time Frame: Min. 2 years ]
    As assessed by total hospital days in/out
