What is bronchoscopic lung volume reduction for emphysema (blvr)?

Bronchoscopic Lung Volume Reduction (BLVR) for Emphysema BLVR, which uses small endobronchial valves, is a new, minimally invasive treatment option that has shown to greatly improve quality of life for patients with severe emphysema. Patients who have undergone this procedure experience benefits, including: Ability to walk longer distances

What is blvr for COPD?

BLVR provides another therapeutic option for patients with COPD. It is an innovative procedure that is improving the quality of patient’s lives daily when properly prescribed and utilized.

How effective is the LVRS procedure for emphysema?

While effective, the LVRS procedure helps only a select patient population with severe emphysema and is associated with a high cost, the potential for postoperative surgical complications and related lengthy hospital stays, and other surgical risks.

How does blvr treat dyspnea?

BLVR treatments generally affect dyspnea by reducing hyperinflation and residual volume (RV). Benefits of treatment are associated with improvement in lung function parameters (forced expiration volume in the first second, total lung capacity, RV, and 6-minute walking test) and quality of life.

What is BLVR procedure?

The bronchoscopic lung volume reduction (BLVR) procedure is an innovative way to treat patients with emphysema using bronchoscopic technology.

How long does it take to get a BLVR?

This procedure is called a bronchoscopy. It is performed under either moderate sedation or general anesthesia. It takes around an hour to complete.

What is the term for a lung that is stretched beyond its normal capacity?

Some patients with advanced emphysema suffer from lung hyperinflation. This means the lungs are stretched beyond their normal capacity. Signs and symptoms include:

Can you take an X-ray of your lungs while asleep?

Once the valves are placed, they can be removed if needed. An initial X-ray of the lungs is taken while you are still asleep to assess for any complications from the procedure.

Can you be admitted to hospital after a BLVR?

Yes. You will be admitted for a minimum of three nights’ stay in the hospital after BLVR procedure for safe monitoring as the valves work to deflate your lung.

What is BLVR in lung?

Bronchoscopic Lung Volume Reduction (BLVR) is a new option for treating emphysema, a form of COPD .

How long does a lung tube procedure last?

This allows the healthy part of the lung to work better. The procedure lasts about an hour, and since there is no incision there is less risk of complications and your recovery time is limited. Patients generally only feel discomfort when the tubes are inserted through the mouth or nose to access the lungs.

What tests are done for a pulmonologist?

Additional studies will be ordered by the treating pulmonologist and may include ventilation/perfusion scan, 6-minute walk test, or ABG.

Is a bronchoscopic procedure considered surgery?

Bronchoscopic procedures require no incision, so it is not considered surgery.

What is BLVR treatment?

BLVR can help people with severe emphysema that doesn’t improve with other standard treatments, such as medications, pulmonary rehabilitation, and oxygen treatment. BLVR improves patients’ lung function and quality of life with benefits such as: Reduced lung volume without removing sections of lung tissue.

What is BLVR for pulmonary rehabilitation?

BLVR is best for patients who are taking the maximum medical therapy and doing pulmonary rehabilitation, which is specialized physical therapy for lung conditions. Our specialists thoroughly evaluate patients with severe emphysema to ensure that BLVR is right for them.

What is BLVR surgery?

BLVR is a minimally invasive alternative to traditional lung volume reduction surgery to treat severe emphysema. In BLVR, our interventional pulmonologists place tiny, one-way valves in the airways in the hyperinflated emphysematous sections of the lungs. The valves prevent air from entering the diseased areas but allow trapped air ...

Why do doctors use bronchoscopes?

The doctor uses the bronchoscope to study lung ventilation and place tiny valves into the airways leading to the hyperexpanded sections of the lungs.

How does a BLVR valve work?

With BLVR, the valves direct air to healthier sections of the lung, allowing those sections to function more normally.

What is a noninvasive lung function test?

Pulmonary function tests: Noninvasive tests to measure airflow in and out of the lungs, how well the lungs move oxygen into the bloodstream, and lung size

How does emphysema affect the lungs?

With emphysema, damaged lung tissue prevents patients from completely exhaling, trapping a significant volume of air in the lungs. As the person continues breathing, the lungs expand, becoming overinflated as they try to take in fresh air to supply the body with oxygen.

What is BLVR treatment?

BLVR, which uses small endobronchial valves, is a new, minimally invasive treatment option that has shown to greatly improve quality of life for patients with severe emphysema.

How does BLVR work?

During this minimally invasive procedure, a physician places tiny valves in the airways to block diseased parts of the lungs to reduce hyperinflation. This helps the healthier parts of the lungs to expand and lifts pressure off the diaphragm, decreasing shortness of breath and making breathing easier.

What is the phone number for BLVR?

If you would like to talk with our care team to determine if you may be a candidate for BLVR, call 41 4-805-3666. If you are a physician with a patient who may be a candidate for BLVR or you would like more information, please call 414-805-4700.

How many people have emphysema?

Emphysema is an advanced form of chronic obstructive pulmonary disease (COPD). Doctors estimate that more than 24 million people in the United States have emphysema or another form of COPD.

What is the treatment for pulmonary fibrosis?

As the disease progresses, oxygen therapy and pulmonary rehabilitation may be prescribed. Once medical therapy has achieved maximum benefit, the remaining options for treatment have been limited to surgical lung volume reduction or lung transplantation, until recently.

Can smoking cause emphysema?

The most common cause of emphysema is cigarette smoking. Quitting smoking can help prevent you from getting the disease. If you already have emphysema, not smoking might keep it from getting worse.

Is emphysema curable?

While COPD and emphysema are not curable, there are treatments that can help you manage the disease. Treatment for emphysema varies based on your symptoms, but often begins with medication management including inhalers and medications to manage symptoms.

What is BLVR for emphysema?

Until recently, treatment options for emphysema were limited to pharmacological treatment, or for patients that qualified, invasive procedures, such as lung volume reduction surgery (LVRS) or lung transplant. Bronchoscopic lung volume reduction (BLVR) with endobronchial valves is a relatively new, minimally invasive treatment option available for a subgroup of patients suffering from the debilitating symptoms of severe emphysema. This procedure has shown significant clinical benefits including improvements in lung function, shortness of breath, and quality of life. Specifically, for some patients with emphysema with hyperinflation, these benefits were achieved by ultimately improving gas exchange and allowing healthier parts of the lung to re-expand.

What is BLVR for COPD?

BLVR provides another therapeutic option for patients with COPD. It is an innovative procedure that is improving the quality of patient’s lives daily when properly prescribed and utilized. “As a respiratory therapist, having treated and been an advocate for COPD patients for many years, it gives me joy to help bring this procedure to patients and their caregivers. This procedure gives patients and their caregivers the opportunity to improve the quality of their lives.” Jen Gerenraich, Respiratory Territory Manager, Respiratory Therapist.

How long does it take to get a BLVR?

Once the patient has met eligibility criteria, they can be scheduled for the BLVR procedure. It is recommended that that the procedure occur within 6 months of testing and patient assessment. Each individual patient may respond somewhat differently, but most patients respond favorably. Response time varies from very rapid (within days) to a few weeks, or up to 3-4 months. Physicians typically recommend a pulmonary rehabilitation program following the procedure to maximize the benefits of this procedure; some treating physicians recommend rehab prior to the procedure as well.

How long should you stay in the hospital for a pneumothorax?

The general recommendation is to keep the patients at the hospital until the initial risk of post-procedural pneumothorax have passed, which is approximately 72 hours.

What is respiratory therapy?

The respiratory therapy community is committed to providing optimal patient care to those with cardiopulmonary health issues. These dedicated healthcare professionals provide critical respiratory services and often follow the patient throughout their entire treatment plan. Chronic obstructive pulmonary disease (COPD) is a common diagnosis among a respiratory therapist’s patient base; COPD is one of the leading causes of death worldwide and in the United States, with nearly 16 million people diagnosed. 1 Of those 16 million, at least 5 million people suffer from emphysema, one of COPD’s main presentations, involving progressive damage of lung tissue and distal airway (alveoli). This condition often results in hyperinflation of the lung, causing significant breathing challenges for patients. 1

Is endobronchial valve permanent?

As published in recent clinical trials, 2 endobronchial valves provide a strong risk-benefit profile on the selected patient population with statistically significant and clinically meaningful improvements in FEV1, target lobe volume reduction, dyspnea score, and quality of life parameters. Treatment with endobronchial valves is intended to be permanent, although removal of the valves is possible, if required. The procedure is typically performed under general anesthesia or deep sedation.

Is BLVR a good treatment for emphysema?

Like any surgical intervention, patient selection is very important in ensuring success of the BLVR procedure. This treatment option is not suitable for all emphysema patients. To determine which patients are likely to benefit the most, an expert clinical evaluation, pulmonary function tests (PFTs), examination of comorbidities, as well as a medical workup and radiographic assessment of a patient’s CT scan are necessary. In accordance with the GOLD Guidelines, 3 patients with Stage III or Stage IV emphysema will be most likely to benefit from this procedure. Common characteristics of a potential candidate can include severe dyspnea, and those with heterogenous emphysema and significant hyperinflation.

When was the National Emphysema Treatment Trial published?

Results of the National Emphysema Treatment Trial (NETT), published in New England Journal of Medicine in 2003, convincingly demonstrated improvement in lung function and symptomatic relief of patients with severe emphysema with lung volume reduction surgery (LVRS).

How many patients were treated in LIBERATE?

LIBERATE included 160 patients and randomized 128 to treatment with endobronchial valves and compared them with 62 patients treated by standard of care (optimized bronchodilator therapy and pulmonary rehabilitation).

Who makes Zephyr valves?

In June 2018, the FDA approved Zephyr endobronchial valves, manufactured by Pulmonx, as the first bronchoscopic treatment for emphysema in the United States for patients with hyperinflation and minimal collateral ventilation. The role of these endobronchial valves in the management of emphysema was evaluated in the LIBERATE study published in American Journal of Respiratory and Critical Care Medicine in 2018.

Is bronchioscopy a less invasive procedure?

Bronchoscopic lung volume reduction has emerged as a potential alternative to LVRS, and a less invasive method by which to achieve lung volume reduction in patients with emphysema and hyperinflation.

Is LVRS effective for emphysema?

While effective, the LVRS procedure helps only a select patient population with severe emphysema and is associated with a high cost, the potential for postoperative surgical complications and related lengthy hospital stays, and other surgical risks.

What is BLVR in lung?

Among these is bronchoscopic lung volume reduction (BLVR), a relatively new nonsurgical procedure available at the Penn Lung Center for patients with COPD who meet certain criteria.

What is BLVR valve?

BLVR uses implantable implantable, endobronchial, one-way valves to prevent reinflation once air has escaped a targeted lobe. In a fully occluded lobe, this will precipitate intentional deflation, leading to a reduction in air trapping and hyperinflation.

What are the factors that determine the benefit of Penn Lung Center?

A: To predict who may experience a substantial benefit, Penn Lung Center specialists consider the degree of hyperinflation/air trapping, the degree of heterogeneity of lung destruction, and fissure completeness. Our patient experience parallels that seen in the clinical trials where patients with more air trapping and more heterogenous disease tend to have the best results.From the clinical trials, using those trial criteria, patients with heterogeneous disease typically experience improvements in 6MWD of close to 100 yards with improvements in FEV1 of 100-200cc. The results in patients with homogenous disease are typically more modest.

Which lobes are not collateral ventilation?

At bronchoscopy, the absence of collateral ventilation to the right middle lobe and right upper lobe was confirmed. A total of 7 endobronchial valves were deployed in these targeted lobes.

Does LVRS improve quality of life?

Among the important findings of NETT was that LVRS affords a substantial improvement in quality of life by comparison to optimal medical therapy in persons with predominantly upper-lobe emphysema and low baseline exercise capacity.

What is BLVR treatment?

Bronchoscopic lung volume reduction (BLVR) procedure has expanded the treatment spectrum of patients with end-stage emphysema. These treatments include valve, coil, thermal vapor ablation, bio-lung volume reduction, targeted lung denervation, and airway bypass stent. This short review provides an up-to-date information on BLVR treatments, their clinical benefits, and an overview of complications. BLVR treatments generally affect dyspnea by reducing hyperinflation and residual volume (RV). Benefits of treatment are associated with improvement in lung function parameters (forced expiration volume in the first second, total lung capacity, RV, and 6-minute walking test) and quality of life. Serious potential pulmonary complications, such as pneumothorax, pneumonia, respiratory failure, and chronic obstructive pulmonary disease exacerbation, may also occur after BLVR treatment. In addition to these, low-cost BLVR methods, such as autologous blood and fibrin glue, are in the developmental stage. Bronchoscopic lung volume reduction treatments are a promising method with positive results for patients with severe emphysema. The widespread use of these techniques, inadequate selection of patients, and non-critical and, therefore, unsuccessful use of BLVR in non-specialist centers lead to a false negative impression of the effectiveness of these techniques. In addition to these considerations, it is obvious that these treatments, which are quite expensive, are burdening social health systems. The reduction of costs or the development of lower-cost treatment methods is important for the future and for the availability of treatments.

How does BLVR affect dyspnea?

BLVR treatments generally affect dyspnea by reducing hyperinflation and RV. Individually, they have different mechanisms of action and are not suitable for every patient. Endobronchial valves (EBVs) reduce air trapping, coils improve the elastic recoil of the lungs, BioLVR and TVA create a local inflammatory reaction, ABS blocks the airway, and TLD reduces bronchoconstriction through innervation (Table 2) [6].

What is biolvr in bronchioles?

BioLVR or polymeric LVR is a method of bronchoscopic instillation of hydrogel into the target lobe that is intended to block lung tissue in patients with advanced emphysema. AeriSeal (Aeris Therapeutics, Inc., Woburn, MA, USA) is a foam-like liquid medium used in bronchioles and alveoli with 10 mL (low dose) or 20 mL (high dose) for each part. The application of the polymer foam is an irreversible BLVR procedure. Bronchoscopically applied polymer resin causes fibrosis in the targeted pulmonary parenchyma. A subsequent inflammatory reaction functions to decrease the tissue in the target regions and reduce volume. In the first study, which included 14 patients and was published in 2011, a positive therapeutic effect was apparent but so were complications, mainly due to inflammatory processes [40]. The results reported included an FEV1increase of +15.9% predicted, a 6MWT increase of 28.7 m, RV/TLC change of −7.4% predicted, forced vital capacity (FVC) increase of 24.1% predicted, DLCO change of +9.3%, and SGRQ score change of −9.9 points [40].

How are endobronchial valves inserted?

Endobronchial valves (Spiration, Inc., Redmond, WA, USA) are inserted bronchoscopically into the targeted segmental or subsegmental bronchi. With regard to blocking, they only allow a unidirectional flow of air during expiration, so that the treated lung section is vented, and the following atelectasis formation achieves the desired volume-reducing effect. The procedure can be performed under mild sedation as a standard bronchoscopic intervention. Patients with collateral ventilation or parenchymal connections in the relevant lung lobe are not suitable for this procedure. If collateral ventilation (short-circuit connection) is present, the desired atelectasis does not occur in the targeted lobe after valve insertion. With planned valve therapy, the likelihood of a good response to therapy by computed tomographic analysis may indicate completeness of interlobar fissures, and/or the direct determination of collateral ventilation with the Chartis system can be estimated during bronchoscopy [11,12].

What is lung volume reduction surgery?

Lung volume reduction surgeries is based on the principle of resecting damaged lung parenchyma and reducing hyperinflation in selected patients with heterogeneous emphysema with upper lobe predominance. Patients are often selected for surgery in accordance with the National Emphysema Treatment Trial (NETT) criteria [5]. Patients with hypercapnic respiratory failure, which is defined as an arterial partial pressure of carbon dioxide (PaCO2) >60 mmHg, and oxygen therapy requirement during rest are not recommended for surgery. LVRS can reportedly improve exercise capacity, lung function, and quality of life, especially in patients with upper lobe emphysema [5]. However, patient selection is limited due to high postoperative non-fatal pulmonary complications and short-term mortality of 6.9% [5]. In addition to medical treatment and surgery, BLVR treatments, especially in specific types of patients, have reportedly yielded promising short- to medium-term results [6–10]. After these results, the BLVR treatment methods (valve and coil) were introduced into the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 guideline [4]. The guideline states that LVRS or BLVR treatments can be considered only in a refractory situation to optimal medical treatment. However, it has been reported that patients who are not eligible for both treatment methods may be candidates for lung transplantation if their forced expiration volume in the first second (FEV1) values are <25% [4].

What are the treatments for emphysema?

At present, standard treatment options include smoking cessation, bronchodilation, mucolytic agents, phosphodiesterase 4 inhibitors, respiratory rehabilitation, and nutritional support, vaccination against influenza and pneumococcus, and long-term oxygen therapy [4]. These treatments help to increase the exercise capacity of patients and decrease symptom exacerbation. However, they do not cure the pathophysiology of the disease or prevent disease progression. In the last decade, in addition to lung volume reduction surgeries (LVRSs), bronchoscopic lung volume reduction (BLVR) has expanded the treatment spectrum of patients with end-stage emphysema [5,6]. These treatments include valve, coil, thermal vapor ablation (TVA), bio-lung volume reduction (BioLVR), targeted lung denervation (TLD), and airway bypass stent (ABS).

How effective is EBV?

George’s Respiratory Questionnaire (SGRQ) [20], and significant improvements have been reported. Studies conducted from 2010 to 2017 collectively indicate that the mean FEV1increases to 77.5 mL (34.5–140 mL) and 13.7% (4.3%–20.7%), the mean RV decreases to 440 mL (200–680 mL), and the mean 6MWT increases to 40.8 m (9.3–91.0 m) (Table 3) [13–20].

What is the FDA approved valve for emphysema?

Endobronchial valves are the first FDA-approved, minimally invasive devices available in the United States to treat patients with severe emphysema. These groundbreaking valves allow one lobe of the lung to deflate and release the trapped air. This lets healthier parts of the lung expand and take in more air.

How long does it take to get a BLVR?

The procedure takes about an hour and requires no cutting or incisions.

What is the number to call for BLVR?

If you or your doctor have any questions about BLVR, please call the Inova Lung Services patient navigator at 703-776-4712.

Who is Eligible for Endobronchial Valves?

Using specialized tests, our interventional pulmonology team determines in advance whether a patient is a good candidate for BLVR treatment with endobronchial valves. We conduct a diagnostic workup that may include pulmonary function testing, a CT scan, cardiac function tests and other tests to ensure the patient is a good candidate for treatment.
