Is the Zephyr valve the best treatment option for emphysema?
“This level of evidence is an important factor for providers and payers who are seeking to deliver the best treatment options for patients with severe emphysema, a severe form of COPD,” French added. According to Pulmonx, more than 15,000 patients have been treated with the Zephyr Valve worldwide since 2007.
What is the role of valves and coils in the treatment emphysema?
While valves and coils can be used for lung volume reduction in both upper- and lower-lobe emphysema, PLVR and BTVA are reserved for patients with upper-lobe predominant emphysema. Patients with homogeneous emphysema may also benefit from ELVR, but because of the low amount of evidence available, they should only be treated in clinical trials.
What are Zephyr valves and are they safe?
“As a physician who treats these patients, the Zephyr Valves are the first FDA-approved minimally-invasive option we have had to help patients breathe easier once optimal medical therapy is no longer effective in controlling their symptoms,” Criner said.
What is the best bronchoscopy for emphysema?
Endoscopic bronchial valve placement The most frequent and best-studied bronchoscopic technique for treating emphysema to date is endobronchial valve (EBV) therapy.
What is the success rate of the Zephyr valve?

Are Zephyr valves any good?
For patients with severe COPD or emphysema, a new treatment option known as the Zephyr® Endobrachial Valve System has proved successful in improving lung function, exercise capacity and quality of life.
Which invasive treatment is used in severe advanced emphysema?
Bronchoscopic lung volume reduction (BLVR) with one-way endobronchial valve (EBV) is a minimally invasive treatment that has been shown to improve clinical outcomes in patients with advanced emphysema and severe hyperinflation.

Can you stop emphysema from progressing?
Emphysema can't be cured. It's progressive, so over time it will get harder and harder for you to catch your breath. But you might not know you have the disease for the first few years unless your doctor tests your breathing.
What is the life expectancy of someone with emphysema?
Because most patients aren't diagnosed until stage 2 or 3, the prognosis for emphysema is often poor, and the average life expectancy is about five years.
What is a zephyr valve?
Zephyr valves are small, minimally invasive synthetic valves developed by Pulmonx Corporation to improve the breathing capacity of people with respiratory illnesses. Approved by the U.S. Food and Drug Administration (FDA) in July 2018, the valves block damaged lung airways, helping healthy lung tissue to work more efficiently.
What happens when a patient inhales?
Once the patient inhales, the Zephyr valve closes, preventing air from entering the damaged part of the lung. During exhalation, the valve opens again to let out the trapped air, which relieves pressure inside the lungs.
What is the gold valve?
The Global Initiative for Chronic Obstructive Disease (GOLD) recommends the use of endobronchial valves — such as the Zephyr Valve — for bronchoscopic lung volume reduction (BLVR) as a standard treatment for people with emphysema or less severe forms of chronic obstructive pulmonary disease (COPD). GOLD considers there is “A” rated evidence (the ...
What is the FDA's designation for the Zephyr valve?
The Zephyr Valve was granted Breakthrough Device designation, meaning the FDA provided intensive interaction and guidance to the company on efficient device development, to expedite evidence generation and the agency’s review of the device.
Who approved the Zephyr valve?
The FDA reviewed the Zephyr Valve device through the premarket approval review pathway, a regulatory pathway for the highest risk class of devices. The FDA granted approval of the Zephyr Valve device to Pulmonx Inc.
What is the Zephyr Endobronchial Valve?
The U.S. Food and Drug Administration today approved a new device, the Zephyr Endobronchial Valve (Zephyr Valve), intended to treat breathing difficulty associated with severe emphysema. “Treatment options are limited for people with emphysema who have severe symptoms that have not improved from taking medicines.
How many people have emphysema?
The Centers for Disease Control and Prevention estimates that 3.5 million American adults have been diagnosed with emphysema. Emphysema, including severe emphysema, is a type of chronic obstructive pulmonary disease (COPD) due to damage to the air sacs (alveoli) in the lungs. Lung damage from emphysema is irreversible.
Can a zephyr valve be used in a hospital?
As a result, the body may not get the oxygen it needs. Using a flexible bronchoscope, a doctor places Zephyr Valves, similar in size to pencil erasers, into the diseased areas of the lung airways during a procedure in a hospital setting.
Can emphysema cause lungs to get bigger?
The damaged alveoli can cause used air to become trapped in the lungs during exhalation. This can cause the diseased parts of the lung to get larger and put pressure on the healthy part of the lung, which makes it difficult to breathe.
Is Zephyr Valve contraindicated?
The Zephyr Valve device is contraindicated for patients with active lung infections; those who are allergic to nitinol, nickel, titanium or silicone; active smokers and those who are not able to tolerate the bronchoscopic procedure.
How many EBV events occurred in a 12-month period?
The major post-procedural complication was pneumothorax with 46 pneumothorax events occurring in 44 EBV subjects (34.4 %) during the 12-month period. Eight of these events did not require any intervention (observation only). A total of 38 of the 46 pneumothoraces (83%) were managed with a placement of a chest tube; 12 of these events also required the removal of at least one valve. None of the pneumothoraces occurring in the longer-term period required the removal of any valves for their management. A total of 43 of the 46 pneumothoraces occurred within 13 days of a recent bronchoscopy procedure, of which 35 (76%) occurred within the first 3 days as shown in Figure 7, for a median event onset time of 1.0 day from a recent bronchoscopy procedure.
What is BLVR in lung?
Bronchoscopic lung volume reduction (BLVR) with Zephyr EBV is a breakthrough approach for reducing hyperinflation in patients with severe emphysema. This multicenter randomized controlled trial demonstrates that Zephyr EBV treatment in patients with severe emphysema selected for little to no collateral ventilation between the treated and the ipsilateral lobe resulted in significant lobar volume reduction, with consequent reduction in hyperinflation, and clinically meaningful improvements in dyspnea, lung function, exercise-capacity, and quality of life. Similar results have been reported previously ( 14 – 17 ).
Is Zephyr EBV good for lung function?
Zephyr EBV treatment in carefully selected patients with little or no collateral ventilation in the target lobe provides clinically meaningful and statistically significant benefits in lung function, exercise tolerance, dyspnea, and quality of life over current SoC medical therapy out to at least 12 months. The benefits are comparable with those seen with LVRS but with a reduction in post-procedure morbidity. BLVR with the Zephyr EBV provides a viable treatment option for patients with severe emphysema and hyperinflation.
What is the cause of breathlessness?
Chronic obstructive pulmonary disease (COPD) causes severe breathlessness, poor quality of life and premature death in millions of people worldwide. The impact of medical therapies is modest at best. 1 Many patients (and indeed medical professionals) assume the lung disease causes reduced oxygen in the blood and therefore breathlessness. An understanding that this is not the main mechanism of breathlessness has been important in the development of non‐pharmacological treatment options. 2
What happens to the lung when you exercise?
3 Consequently, at rest, the lung sits at a high volume with the volume rising rapidly on exercise.
