Bronchial Thermoplasty

Ascension Providence is excited to announce a breakthrough procedure in the treatment of asthma. Bronchial thermoplasty (BT) is a non-drug procedure for severe, persistent asthma in patients 18 years and older whose asthma is not well-controlled with inhaled corticosteroids and long-acting beta agonists such as Advair®, Symbicort® and Dulera®.

How Bronchial Thermoplasty Works

The Alair® Bronchial Thermoplasty System (the “Alair System”) delivers thermal energy to the airway wall in a precisely controlled manner in order to reduce excessive airway smooth muscle (ASM). Reducing airway smooth muscle decreases the ability of the airways to constrict, thereby reducing the frequency of asthma attacks.

The BT Procedure

BT is a minimally invasive bronchoscopic procedure performed in three outpatient procedure visits, each treating a different area of the lungs and scheduled approximately three weeks apart. After all three procedures are performed, the bronchial thermoplasty treatment is complete. The procedures are performed at Ascension Providence by Dr. Maydee A. Rosario and Dr. Boris A. Murillo, both of Waco Lung Associates.

BT Complements Asthma Medications

BT is expected to complement current asthma maintenance medications by providing long-lasting asthma control and improving asthma-related quality of life of patients with severe asthma.

BT Benefits and Risks

Benefits of BT

One year follow-up indicates…

  • 32 percent reduction in asthma attacks
  • 84 percent reduction in emergency room visits for respiratory symptoms
  • 73 percent reduction in hospitalizations for respiratory symptoms
  • 66 percent reduction in days lost from work/school/ other daily activities due to asthma
  •  Improved asthma quality of life

Two year follow-up indicates…

  • Reductions in asthma attacks, ER visits and hospitalizations for respiratory symptoms are maintained

Stable safety profile observed out to five years

Risks of BT

  • In the period immediately following BT, there is an expected increase and worsening of asthma-related respiratory symptoms
  • These events typically occur within a day of the procedure and resolve on average within seven days with standard care
  • There is a small possibility (3.4 percent per procedure) that the temporary worsening of asthma symptoms after a procedure may result in the patient being admitted to the hospital for management of asthma symptoms
