Survival Rates Study of Patients Treated with BLVR
In a first-of-its-kind study, researchers examined the survival rate of severe COPD/emphysema patients undergoing Bronchoscopic Lung Volume Reduction (BLVR) vs. patients who were evaluated for BLVR but not treated.
This single-center, non-randomized, retrospective analysis included 1,471 patients.
The study found that patients treated with BLVR1:
- Had a statically significant survival rate of 1.7 years longer than the non-treated group
- Were 41% less likely to die over the course of the study
The study authors concluded: “BLVR treatment was found to be an independent predictor of survival when adjusting for other survival-influencing factors such as age, gender, or severity of disease.”
In the study described above, the BLVR group comprised 483 patients and the non-BLVR group comprised 988 patients. Of the BLVR group, 73% of patients received BLVR with Zephyr® Valves and 27% received endobronchial coils [a technology that is not approved in the United States].
