View clinical trials related to Heterogeneous Emphysema.
Filter by:To compare the clinical outcomes of Endoscopic Lung Volume Reduction (ELVR) using Pulmonx Zephyr Valves vs. Standard of Care (SoC) in the treatment of heterogeneous emphysema subjects in a controlled trial design setting.
This clinical trial evaluates the impact of catheter-based measurement of interloabr collateral ventilation prior to endoscopic lung volume reduction in patients with hetereogeneous emphysema and complete interlobar fissures in high resolution computed tomography.
Hypothesis: Patients with advanced emphysema with predominance of the disease in areas other than the upper lobes, as determined by high resolution computed tomography (HRCT), could have a positive response to valve treatment.
The purpose of this study is to evaluate the safety and feasibility of the Chartis System in measuring air flow and pressures in isolated lung compartments in emphysema patients prior to endobronchial lung volume reduction (ELVR).
