New scan could boost success of lung valve treatment for emphysema
NCT ID NCT07403617
First seen Feb 15, 2026 · Last updated Jun 20, 2026 · Updated 21 times
Summary
This study tests whether a special scan (VQDI) can help doctors pick the best lung area to place tiny valves for severe emphysema. About 285 participants will be randomly assigned to have valve placement guided by either the new scan or the usual CT scan. The goal is to see if the new method leads to better breathing and lung function after six months.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
endobronchial valve placement
What this could lead to
If successful, this could make a standard procedure more effective for people with severe emphysema, leading to better breathing and quality of life.
What could go wrong
This is a relatively small, early-stage trial. The new method may not prove better than the current approach, and valve placement carries risks like infection or lung collapse.
