An endobronchial valve (EBV) is a small, one-way device placed in the airways of the lungs through a minimally invasive bronchoscopic procedure. Engineered to allow air and secretions to exit but not enter, EBVs are primarily designed to treat patients suffering from certain forms of Chronic Obstructive Pulmonary Disease (COPD), emphysema and persistent air leaks within the lungs.

By strategically placing EBVs, physicians can redirect airflow, promote collapse of diseased lung regions (a process known as "lung volume reduction"), and improve breathing efficiency in targeted areas.

EBVs are crafted from biocompatible materials and shaped to snugly fit the bronchial passages. Valve placement does not require open surgery, making the procedure less risky and often associated with faster recovery times compared to traditional surgical interventions.

Why Might a Patient Need an EBV?

Endobronchial valves are most commonly considered for patients with severe Chronic Obstructive Pulmonary Disease (COPD) and symptomatic emphysema—especially those who have hyperinflated lungs and whose symptoms are not sufficiently managed with medication alone.

The primary goals of EBV placement are to:

• Improve lung function and oxygenation
• Reduce breathlessness (dyspnea) and fatigue
• Minimize the need for invasive surgery
• Enhance overall quality of life

Candidates for EBV therapy typically have exhausted conventional treatment options and are seeking alternatives to surgical lung volume reduction. A multidisciplinary team carefully evaluates each patient’s medical history, imaging studies, and pulmonary function tests to determine eligibility.  

Patients who may benefit from EBV therapy often experience a constellation of symptoms associated with advanced emphysema or unresolved air leaks. Common symptoms include:

• Persistent shortness of breath, even at rest or with minimal exertion
• Frequent coughing episodes
• Reduced exercise tolerance
• Chronic fatigue and weakness
• Wheezing or difficulty breathing
• Recurrent lung infections
• Failure of traditional medical therapies to control symptoms
• Ongoing chest discomfort or pain due to air leaks or collapsed lung regions  

Referral for EBV placement is often considered when these symptoms significantly impair daily living or when imaging reveals regions of the lung that remain over-inflated despite standard treatments.  

Our center offers a full spectrum of care surrounding endobronchial valve therapy, from initial evaluation to post-procedural support. Services include:

• Detailed Diagnostic Assessment: Comprehensive pulmonary function testing, high-resolution CT imaging, and bronchoscopic evaluation to identify candidate lung regions for valve placement.
• Multidisciplinary Consultation: Collaborative treatment planning involving pulmonologists, thoracic surgeons, radiologists, and respiratory therapists to ensure the best possible outcomes.
• EBV Placement Procedure: Minimally invasive bronchoscopic insertion of one or more valves under sedation in a hospital setting, tailored to each patient’s anatomy and disease pattern.
• Post-Placement Monitoring: Regular follow-up visits to assess valve function, monitor for complications, and evaluate symptom improvement through physical exams and repeat imaging.
• Symptom Management: Ongoing assessment and adjustment of supplemental oxygen, inhaled therapies, and other medication regimens to maximize breathing comfort.
• Pulmonary Rehabilitation: Customized exercise and education programs designed to build endurance, strengthen respiratory muscles, and enhance overall mobility following EBV placement.
• Complication Management: Prompt intervention for any valve-related complications, such as migration, infection, or airway blockage, with access to emergency bronchoscopic care if needed.
• Patient Education: Clear guidance on living with EBVs, recognizing warning signs, and making necessary lifestyle changes to support respiratory health.
• Support and Counseling: Emotional support and access to community resources for patients and families coping with chronic lung conditions.
• Transition to Home Care: Coordination with home health services to ensure safe recovery and continuity of care after discharge.

Initial Consultation:

Patients begin with a thorough clinical assessment to confirm diagnosis and rule out contraindications. This may include spirometry, imaging studies, and discussions of prior treatment success and failure.

Procedure Day:

The bronchoscopic EBV placement is performed in an outpatient or inpatient setting. Patients receive sedation and the procedure typically lasts 30-60 minutes. Most return home within 24 hours.

Long-Term Care:

Valves may remain in place for months or years depending on individual response. Following EBV placement, ongoing care and management can be provided by monitored by your referring pulmonologist.
