This systematic review and meta-analysis evaluated the impact of endobronchial valve (EBV) treatment on mortality in patients with severe emphysema, analyzing data from six randomized controlled trials involving 819 patients. The study found that peri-procedural mortality was significantly higher with EBV (Peto OR 3.70), while post-procedural mortality and overall mortality did not differ significantly between EBV and standard care groups.
Key findings
- Peri-procedural mortality was significantly higher with EBV treatment (Peto OR 3.70, 95% CI 1.07-12.84; p = 0.03).
- Post-procedural mortality did not show a significant increase (Peto OR 0.50, 95% CI 0.12-2.09; p = 0.33).
- Overall mortality rates were not significantly different between EBV and standard care (Peto OR 1.57, 95% CI 0.61-4.04; p = 0.35).
Why it matters
Understanding the mortality risks associated with endobronchial valve treatment is crucial for clinicians in making informed decisions about patient management and counseling, particularly regarding the timing of potential complications.
