Asthma Treatment – Bronchial Thermoplasty


An estimated 25 million people in the U.S. suffer from asthma – a respiratory disease that causes the airways in the lungs to narrow and makes it difficult to breathe. For some, this condition can significantly impact their quality of life and, in some cases, can be life threatening. According to the Asthma and Allergy Foundation of America (AAFA), asthma accounts for approximately 44,000 asthma attacks, 4,700 emergency room visits, 1,200 hospitalizations and 9 deaths every day in the U.S.

Bronchial Thermoplasty (BT) delivered by the Alair™ System is not a medication – it is a safe outpatient procedure that uses mild heat to actually reduce the amount of excess airway smooth muscle tissue in the airways. Less muscle tissue means less airway constriction during an asthma attack. Patients can breathe more easily—and are less likely to have an asthma attack.
Unlike daily asthma medications, BT continues to work for years. BT is an add-on therapy to a patient’s current asthma medications, providing long-lasting benefits for patients, including a decrease in asthma attacks, fewer emergency room visits and improved asthma-related quality of life.

In a clinical study of patients with severe asthma, 79% of patients treated with Bronchial Thermoplasty (BT) saw a significant improvement in their asthma-related quality of life.2 In addition, patients treated with BT experienced:
• 32% fewer severe asthma attacks2
• 84% fewer asthma-related emergency room visits2
• 66% fewer days lost from work, school, and daily activities due to asthma symptoms

Lasting benefits: Improvements in quality of life and days lost due to asthma symptoms were followed for one year. 2 Reductions in asthma attacks and emergency room visits were shown to extend through a 2-year follow-up period.

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.

The Alair™ Bronchial Thermoplasty System is approved by the FDA for the treatment of severe persistent asthma in patients 18 years and older whose asthma is not well controlled with inhaled corticosteroids and long-acting beta-agonists.
