BT reduces asthma attacks by reducing airway smooth muscle

Healthy Airway

Normal airway Airway smooth muscle

With Asthma

Excess airway smooth muscle

Asthma Attack

Constricted airway during an asthma attack Contracted airway smooth muscle

Post BT Treatment

BT reduces asthma attacks by reducing airway smooth muscle

With less smooth muscle, the airways constrict less, reducing asthma attacks and making breathing easier.

See how Bronchial Thermoplasty works to reduce asthma attacks

Fewer asthma attacks means less need for the associated oral steroid treatment—and its side effects.

Bronchial Thermoplasty is clinically proven to reduce asthma attacks for at least 5 years

At one-year (compared to sham), patients with severe asthma who were treated with BT experienced:

  • Fewer asthma attacks

    32%
    decrease in severe asthma attacks1
  • Fewer ER visits

    84%
    reduction in emergency room visits for respiratory-related symptoms1
  • Fewer absences

    66%
    fewer days lost from work, school and daily activities due to asthma1

Reductions in asthma attacks and ER visits were shown to extend through a 5-year follow-up period.2

BT complements your current treatment options to significantly improve your asthma-related quality of life

79%

79% of patients who were treated with BT reported a significant improvement in their asthma-related quality of life1

Bronchial Thermoplasty is delivered by the Alair System in 3 outpatient sessions performed by a BT-Certified pulmonologist

  • Each session treats a different part of the lung to ensure safety
  • During the procedure a carefully controlled device delivers mild heat to the smooth muscle of the airways in your lungs, reducing the amount of excessive smooth muscle
  • No incision is needed; BT is performed with a bronchoscope inserted through the nose or mouth
  • When your BT treatment is complete, you will return to your regular asthma-treating physician to continue managing your asthma

Side effects & things to know

As with any procedure, there are risks, and individual results may vary. The most common side effect of BT is temporary worsening of respiratory-related symptoms. This side effect typically occurs within a day of the procedure and resolves within 7 days on average with standard care. There is a small (3.4% per procedure) risk of these symptoms requiring hospitalization.1

Your BT treatment will be delayed if you currently have any of the following conditions:

  • An active respiratory infection
  • A bleeding disorder
  • An asthma attack in the past 14 days
  • An increased or decreased dose of the oral steroids for asthma in the past 14 days
  • Your doctor says you cannot stop taking the following medications prior to the BT procedure: anticoagulants, antiplatelet agents, aspirin, or non-steroidal anti-inflammatory medications (NSAIDS)

You are not a candidate for BT if you:

  • Are under 18 years old
  • Have a pacemaker, internal defibrillator, or other implantable electronic device
  • Have a known sensitivity to medications required to perform bronchoscopy, including lidocaine, atropine, and benzodiazepines
  • Have been treated previously with BT

Benefits of BT are long-lasting
