Bronchial Thermoplasty

National Jewish Health is one of the first institutions in the United States to offer a procedure for people with severe asthma to help them breathe more easily This procedure is known as bronchial thermoplasty (BT). 

BT is an FDA-approved procedure for the treatment of asthma; it was approved in 2010 for use in people 18 years or older with severe asthma whose symptoms are not well controlled with inhaled corticosteroids and long-acting beta agonists.

Benefits of Bronchial Thermoplasty

In clinical trials, BT has been shown to improve asthma-related quality of life in 79% of people who received treatment.

People treated with BT also had:

  • 84% fewer asthma-related emergency room visits
  • 66% fewer days lost from work, school, and other activities due to asthma symptoms
  • 32% fewer severe asthma attacks.


How Bronchial Thermoplasty Works

BT airway diagram

BT helps to reduce the smooth muscle mass in the airways through delivery of controlled thermal (heat) energy to the airway walls. The thermal energy is delivered to the airway walls over a series of 3 bronchoscopies.

Good Candidates for Bronchial Thermoplasty

You may be a good candidate for the BT procedure if:

  • you are 18 years of age or older,
  • you have severe asthma,
  • and your symptoms are not well controlled despite the use of inhaled corticosteroids and long-acting beta agonists.


Ineligible Candidates for Bronchial Thermoplasty

You are not a candidate for BT if:

  • You have a pacemaker, internal defibrillator, or some other type of implantable electronic device.
  • You have sensitivity to the medications used when performing a bronchoscopy, including benzodiazepines, atropine and lidocaine.
  • You have been previously treated with BT.


Side Effects of Bronchial Thermoplasty

There are few side effects from the BT procedure, but people may experience temporary worsening of respiratory symptoms within one to seven days following the procedure. There is a small risk (3.4%) of these symptoms requiring hospitalization.
