Comparing balloon pulmonary angioplasty and pulmonary endarterectomy for chronic thromboembolic pulmonary hypertension

Balloon Pulmonary anGiOplasty Versus Pulmonary Endarterectomy in Patients With Chronic ThromboEmbolic Pulmonary Hypertension: a Non-inferiority Randomized Trial

Not applicable Interventional University of Aarhus · NCT05110066

This study is testing whether a new procedure called balloon pulmonary angioplasty works better than the traditional surgery for people with chronic thromboembolic pulmonary hypertension.

What this trial studies

This study evaluates the effectiveness of balloon pulmonary angioplasty (BPA) compared to pulmonary endarterectomy (PEA) in patients with chronic thromboembolic pulmonary hypertension (CTEPH) who are eligible for both treatments. It is a multicenter, prospective, randomized, controlled, open-label trial involving 152 patients. Participants will be randomly assigned to receive either BPA or PEA, with follow-up assessments including right heart catheterization at 4 and 12 months post-treatment. The primary endpoint is the change in pulmonary vascular resistance from baseline to these follow-up points.

Who should consider this trial

Good fit: Ideal candidates are patients aged 17 to 80 diagnosed with CTEPH who are eligible for both BPA and PEA.

Not a fit: Patients with a life expectancy of less than 12 months or significant comorbidities affecting their pulmonary hypertension may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a less invasive treatment option for patients with CTEPH who are eligible for both BPA and PEA.

How similar studies have performed: While BPA has shown promise in treating CTEPH, this study represents a novel head-to-head comparison with PEA, which has not been previously conducted.
