Bronchial Thermoplasty

Proven to reduce severe asthma attacks out to at least 5 years1

See How Bronchial Thermoplasty (BT) Reduces Severe Asthma Attacks

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

BT Reduces Severe Asthma Attacks By Reducing Airway Smooth Muscle

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

BT Is The First Non-Drug Treatment For Severe Asthma

  • The outpatient procedure is performed in three sessions using a bronchoscope.
  • Each session takes less than an hour under moderate sedation, and most patients go home the same day.
  • After treatment is complete, you will continue to see your current asthma doctor.

"Since BT, I am back to living the active life I've always loved."

79% of BT patients reported a significant improvement in their asthma-related quality of life.

Risks, Side-Effects, and Other Important Information

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.2

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

These events typically occur within one day of the BT procedure and usually resolve within a week with standard care. There is a small risk (3.4% per procedure) that symptoms may require hospitalization.1
