Bronchial Thermoplasty for Asthma

Asthma is a chronic disease of the lungs, affecting nearly 25 million Americans. If you suffer from severe asthma, an innovative procedure called Bronchial Thermoplasty (BT) reduces the severity and frequency of your symptoms and is now available at Memorial Hermann Memorial City.

Bronchial Thermoplasty Risks

BT is a safe minimally invasive outpatient procedure for the treatment of asthma in adults whose symptoms are not well controlled with inhalers. The treatment uses mild heat to reduce excess smooth muscle in the lungs. Less muscle tissue means less airway constriction during an asthma attack, and fewer asthma attacks overall. Nearly 80% of patients treated with BT see a significant improvement in their asthma related quality of life.

Bronchial Thermoplasty Procedure

Bronchial Thermoplasty is performed by a specially trained pulmonologist over the course of 3 sessions, scheduled about 3 weeks apart. Each session focuses on a different part of the lungs and usually lasts about an hour.

During the procedure, a small catheter is delivered to the lungs through a bronchoscope that is inserted into your mouth or nose. The device then applies mild heat inside the airways to reduce excessive smooth muscle. Each session is performed under moderate sedation and the patient may go home the same day.


Following completion of the 3 BT treatment sessions, the patient will continue visits with their regular asthma-treatment doctor for ongoing asthma management.

Are you a candidate for Bronchial Thermoplasty for Asthma?

  • Are you 18 years of age or older?
  • Do you have X or more severe asthma attacks each month?
  • Are you on maximum-tolerated doses of asthma medications but still experience asthma symptoms or risk of future exacerbations?
  • Do you have two or more exacerbations a year while taking chronic oral corticosteroids?
  • Is your quality of life impaired?
  • Have you visited the ER for asthma-related reasons in the past six months?
  • Have you lost days from work, school or daily activities due to asthma?

If so, Bronchial Thermoplasty could be an effective treatment for you. Bronchial Thermoplasty is approved by the FDA for the treatment of severe asthma in patients 18 years and older whose asthma is not well controlled with inhaled corticosteroids and long-acting beta-agonists. Speak with your physician to help determine if you are a candidate.
